+# Gleam Anchor Framework
+
+A framework for building Solana programs with Gleam, inspired by Rust's Anchor framework.
+
+## Overview
+
+The Gleam Anchor framework provides a structured, type-safe way to build Solana programs in Gleam. It offers:
+
+- **Account validation** - Automatic validation of account constraints (signer, writable, owner)
+- **Instruction dispatch** - Clean pattern for handling different instruction types
+- **Error handling** - Comprehensive error codes matching Solana program errors
+- **PDA support** - Program Derived Address generation
+- **State management** - Structured account state with type safety
+
+## Installation
+
+The Anchor framework is included in the gleam-sbpf compiler. Simply import it:
+
+```gleam
+import anchor.{type AccountInfo, type Context, type ProgramResult}
+```
+
+## Core Concepts
+
+### AccountInfo
+
+Represents a Solana account with all necessary metadata:
+
+```gleam
+pub type AccountInfo {
+  AccountInfo(
+    key: Int,           // Public key
+    lamports: Int,      // Account balance
+    data: List(Int),    // Account data
+    owner: Int,         // Program that owns this account
+    is_signer: Bool,    // Whether the account signed the transaction
+    is_writable: Bool,  // Whether the account is writable
+  )
+}
+```
+
+### Context
+
+The execution context for your program:
+
+```gleam
+pub type Context {
+  Context(
+    program_id: Int,
+    accounts: List(AccountInfo),
+    instruction_data: List(Int),
+  )
+}
+```
+
+### Account Constraints
+
+Validate accounts with built-in constraints:
+
+```gleam
+pub type AccountConstraint {
+  Signer              // Account must be a signer
+  Writable            // Account must be writable
+  Owner(program: Int) // Account must be owned by program
+  Rent                // Account must be rent exempt
+}
+```
+
+### Error Codes
+
+Comprehensive error handling:
+
+```gleam
+pub type ErrorCode {
+  InvalidInstruction
+  InvalidAccountData
+  InvalidAccountOwner
+  AccountNotSigner
+  AccountNotWritable
+  InsufficientFunds
+  IncorrectProgramId
+  MissingRequiredSignature
+  AccountAlreadyInitialized
+  UninitializedAccount
+  Custom(code: Int)
+}
+```
+
+## Example: Counter Program
+
+Here's a complete counter program using the Gleam Anchor framework:
+
+```gleam
+import anchor.{
+  type AccountInfo, type Context, type ProgramResult, Error, Success, Signer,
+  Writable,
+}
+
+/// Counter instruction types
+pub type CounterInstruction {
+  Initialize
+  Increment
+  Decrement
+  Reset
+}
+
+/// Counter account state
+pub type CounterState {
+  CounterState(
+    authority: Int,
+    count: Int,
+    bump: Int,
+  )
+}
+
+/// Initialize counter account
+pub fn process_initialize(ctx: Context) -> ProgramResult(CounterState) {
+  case anchor.get_account(ctx, 0) {
+    Success(counter_account) -> {
+      case anchor.get_account(ctx, 1) {
+        Success(authority) -> {
+          // Validate authority is signer
+          case anchor.validate_account(authority, [Signer]) {
+            Success(_) -> {
+              // Validate counter account is writable
+              case anchor.validate_account(counter_account, [Writable]) {
+                Success(_) -> {
+                  // Initialize counter state
+                  let state = CounterState(
+                    authority: authority.key,
+                    count: 0,
+                    bump: 255,
+                  )
+                  Success(state)
+                }
+                Error(code, msg) -> Error(code, msg)
+              }
+            }
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+
+/// Increment counter
+pub fn process_increment(ctx: Context, current_count: Int) -> ProgramResult(Int) {
+  case anchor.get_account(ctx, 0) {
+    Success(counter_account) -> {
+      case anchor.get_account(ctx, 1) {
+        Success(authority) -> {
+          // Validate authority is signer and counter is writable
+          case anchor.validate_account(authority, [Signer]) {
+            Success(_) -> {
+              case anchor.validate_account(counter_account, [Writable]) {
+                Success(_) -> {
+                  let new_count = current_count + 1
+                  Success(new_count)
+                }
+                Error(code, msg) -> Error(code, msg)
+              }
+            }
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+
+/// Main instruction processor
+pub fn process_instruction(
+  program_id: Int,
+  accounts: List(AccountInfo),
+  instruction_data: List(Int),
+) -> ProgramResult(Int) {
+  let ctx = anchor.create_context(program_id, accounts, instruction_data)
+  
+  case anchor.deserialize_instruction(instruction_data) {
+    Success(discriminator) -> {
+      case discriminator {
+        0 -> process_initialize(ctx) |> map_result(fn(state) { state.count })
+        1 -> process_increment(ctx, 0)
+        _ -> Error(anchor.InvalidInstruction, "Unknown instruction")
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+```
+
+## API Reference
+
+### Account Validation
+
+```gleam
+/// Validate account against a list of constraints
+pub fn validate_account(
+  account: AccountInfo,
+  constraints: List(AccountConstraint),
+) -> ProgramResult(Nil)
+```
+
+Example:
+```gleam
+// Validate account is both a signer and writable
+anchor.validate_account(account, [Signer, Writable])
+```
+
+### PDA Generation
+
+```gleam
+/// Create a Program Derived Address
+pub fn find_program_address(seeds: List(List(Int)), program_id: Int) -> PDA
+```
+
+Example:
+```gleam
+let pda = anchor.find_program_address([[1, 2, 3], [4, 5, 6]], program_id)
+```
+
+### Instruction Deserialization
+
+```gleam
+/// Deserialize instruction data to get discriminator
+pub fn deserialize_instruction(data: List(Int)) -> ProgramResult(Int)
+```
+
+Example:
+```gleam
+case anchor.deserialize_instruction(instruction_data) {
+  Success(0) -> process_initialize(ctx)
+  Success(1) -> process_increment(ctx)
+  _ -> Error(InvalidInstruction, "Unknown instruction")
+}
+```
+
+### Account Initialization
+
+```gleam
+/// Initialize an account with data
+pub fn initialize_account(
+  account: AccountInfo,
+  data: List(Int),
+) -> ProgramResult(AccountInfo)
+```
+
+Example:
+```gleam
+let result = anchor.initialize_account(account, [1, 2, 3, 4])
+```
+
+### Lamport Transfers
+
+```gleam
+/// Transfer lamports between accounts
+pub fn transfer(
+  from: AccountInfo,
+  to: AccountInfo,
+  amount: Int,
+) -> ProgramResult(#(AccountInfo, AccountInfo))
+```
+
+Example:
+```gleam
+case anchor.transfer(from_account, to_account, 1_000_000) {
+  Success(#(new_from, new_to)) -> // Handle successful transfer
+  Error(code, msg) -> // Handle error
+}
+```
+
+### Context Management
+
+```gleam
+/// Create execution context
+pub fn create_context(
+  program_id: Int,
+  accounts: List(AccountInfo),
+  instruction_data: List(Int),
+) -> Context
+
+/// Get account by index from context
+pub fn get_account(ctx: Context, index: Int) -> ProgramResult(AccountInfo)
+```
+
+Example:
+```gleam
+let ctx = anchor.create_context(program_id, accounts, instruction_data)
+case anchor.get_account(ctx, 0) {
+  Success(account) -> // Use account
+  Error(code, msg) -> // Handle error
+}
+```
+
+### Error Handling
+
+```gleam
+/// Convert error code to integer
+pub fn error_code_to_int(code: ErrorCode) -> Int
+
+/// Convert ProgramResult to exit code
+pub fn to_exit_code(result: ProgramResult(a)) -> Int
+```
+
+Example:
+```gleam
+let exit_code = anchor.to_exit_code(result)
+```
+
+## Testing
+
+The framework includes comprehensive unit tests and LiteSVM integration tests.
+
+### Unit Tests
+
+Run the unit tests:
+
+```bash
+gleam test
+```
+
+This runs 29 unit tests covering:
+- Account validation (signer, writable, owner)
+- Multiple constraint validation
+- PDA generation
+- Instruction deserialization
+- Account initialization
+- Lamport transfers
+- Context management
+- Counter program operations
+- Error code conversion
+
+### LiteSVM Integration Tests

+
+## Comparison with Rust Anchor
+
+| Feature | Rust Anchor | Gleam Anchor |
+|---------|-------------|--------------|
+| Account validation | Macros (#[account]) | Function-based |
+| Type safety | Compile-time | Compile-time |
+| Error handling | Result<T, E> | ProgramResult(T) |
+| PDA generation | Macro + seeds | Function-based |
+| Instruction dispatch | Macro-based | Pattern matching |
+| Account constraints | Attribute macros | Explicit validation |
+| State management | Borsh serialization | List-based |
+
+## Advantages
+
+1. **Type Safety** - Full Gleam type system ensures correctness
+2. **Simplicity** - No macro magic, explicit validation
+3. **Testing** - Easy to unit test with pure functions
+4. **Fast Development** - Clean syntax and fast compiler
+5. **Reliable** - No null, no exceptions, comprehensive error handling
+
+## Limitations
+
+Current limitations (potential future improvements):
+
+1. **Serialization** - Currently uses simple list-based data (could add Borsh)
+2. **Account Macros** - Uses explicit validation instead of derive macros
+3. **IDL Generation** - No automatic IDL generation yet
+4. **Client Libraries** - No TypeScript/Rust client generation yet
+5. **Cross-Program Invocation** - Basic support, could be enhanced
+
+## Best Practices
+
+1. **Always validate accounts** - Use account constraints to ensure safety
+2. **Handle all errors** - Never ignore ProgramResult errors
+3. **Use descriptive types** - Define clear state and instruction types
+4. **Test thoroughly** - Write unit tests and integration tests
+5. **Keep state minimal** - Only store necessary data on-chain

+# Gleam Anchor - Quick Start Guide
+
+Get started with the Gleam Anchor framework in 5 minutes!
+
+## Prerequisites
+
+- Gleam 1.13.0+ ([installation guide](https://gleam.run/getting-started/installing/))
+- Erlang/OTP 25+ 
+- Basic familiarity with Solana concepts
+
+## Step 1: Create Your First Program
+
+Create a new file `src/my_program.gleam`:
+
+```gleam
+import anchor.{
+  type AccountInfo, type Context, type ProgramResult, Success, Error, Signer,
+  Writable,
+}
+
+/// Simple program that stores a number
+pub type MyState {
+  MyState(
+    owner: Int,
+    value: Int,
+  )
+}
+
+/// Initialize the program
+pub fn initialize(ctx: Context, initial_value: Int) -> ProgramResult(MyState) {
+  // Get the state account (first account)
+  case anchor.get_account(ctx, 0) {
+    Success(state_account) -> {
+      // Get the owner account (second account)
+      case anchor.get_account(ctx, 1) {
+        Success(owner) -> {
+          // Validate owner must be a signer
+          case anchor.validate_account(owner, [Signer]) {
+            Success(_) -> {
+              // Validate state account is writable
+              case anchor.validate_account(state_account, [Writable]) {
+                Success(_) -> {
+                  // Create initial state
+                  Success(MyState(owner: owner.key, value: initial_value))
+                }
+                Error(code, msg) -> Error(code, msg)
+              }
+            }
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+
+/// Update the value
+pub fn update(ctx: Context, new_value: Int) -> ProgramResult(Int) {
+  case anchor.get_account(ctx, 0) {
+    Success(state_account) -> {
+      case anchor.get_account(ctx, 1) {
+        Success(owner) -> {
+          // Validate permissions
+          case anchor.validate_account(owner, [Signer]) {
+            Success(_) -> {
+              case anchor.validate_account(state_account, [Writable]) {
+                Success(_) -> Success(new_value)
+                Error(code, msg) -> Error(code, msg)
+              }
+            }
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+```
+
+## Step 2: Create the Instruction Processor
+
+Add the instruction handler:
+
+```gleam
+/// Instruction discriminators
+const initialize_instruction = 0
+const update_instruction = 1
+
+/// Main entry point
+pub fn process_instruction(
+  program_id: Int,
+  accounts: List(AccountInfo),
+  instruction_data: List(Int),
+) -> ProgramResult(Int) {
+  let ctx = anchor.create_context(program_id, accounts, instruction_data)
+  
+  case anchor.deserialize_instruction(instruction_data) {
+    Success(discriminator) -> {
+      case discriminator {
+        0 -> {
+          // Initialize with value 0
+          case initialize(ctx, 0) {
+            Success(state) -> Success(state.value)
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        1 -> {
+          // Update to value 42
+          update(ctx, 42)
+        }
+        _ -> Error(anchor.InvalidInstruction, "Unknown instruction")
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+```
+
+## Step 3: Compile to BPF
+
+Compile your program to Solana BPF bytecode:
+
+```gleam
+import compiler
+import my_program
+
+// For this example, we'll create a simple expression
+// In a real program, you'd use the full instruction processor
+pub fn main() {
+  // Initialize with value 0
+  let program = compiler.Return(compiler.IntLiteral(0))
+  
+  case compiler.compile_to_elf(program) {
+    compiler.Ok(bytecode) -> {
+      // Save to file
+      save_to_file("my_program.so", bytecode)
+    }
+    compiler.Error(msg) -> {
+      io.println("Compilation error: " <> msg)
+    }
+  }
+}
+```
+
+Build and run:
+
+```bash
+gleam build
+gleam run
+```
+
+## Step 4: Test Your Program
+
+Create a test file `test/my_program_test.gleam`:
+
+```gleam
+import anchor.{AccountInfo, Context, Success}
+import my_program

+
+## Step 5: Test with LiteSVM
+
+Create a Rust test file `litesvm_tests/tests/my_program_test.rs`:
+
+```rust
+use litesvm::LiteSVM;
+use solana_sdk::{
+    instruction::Instruction,
+    pubkey::Pubkey,
+    signature::{Keypair, Signer},
+    transaction::Transaction,
+};
+use std::fs;
+
+#[test]
+fn test_my_program() {
+    let mut svm = LiteSVM::new();
+    
+    // Load compiled program
+    let program_data = fs::read("../build/my_program.so")
+        .expect("Failed to read program");
+    
+    let program_id = Pubkey::new_unique();
+    let _ = svm.add_program(program_id, &program_data);
+    
+    // Create payer account
+    let payer = Keypair::new();
+    svm.airdrop(&payer.pubkey(), 1_000_000_000).unwrap();
+    
+    // Create instruction (discriminator 0 = initialize)
+    let instruction = Instruction::new_with_bytes(
+        program_id,
+        &[0], // Initialize instruction
+        vec![],
+    );
+    
+    // Create and send transaction
+    let transaction = Transaction::new_signed_with_payer(
+        &[instruction],
+        Some(&payer.pubkey()),
+        &[&payer],
+        svm.latest_blockhash(),
+    );
+    
+    let result = svm.send_transaction(transaction);
+    assert!(result.is_ok(), "Program should execute successfully");
+}
+```
+
+Run LiteSVM tests:
+
+```bash
+cd litesvm_tests
+cargo test --release -- --nocapture
+```
+
+## Common Patterns
+
+### Pattern 1: Multiple Account Validation
+
+```gleam
+let accounts = [state_account, authority, system_program]
+let ctx = Context(program_id, accounts, instruction_data)
+
+// Validate multiple accounts
+case anchor.validate_account(state_account, [Writable]) {
+  Success(_) -> {
+    case anchor.validate_account(authority, [Signer]) {
+      Success(_) -> {
+        // Both accounts validated successfully
+        process_instruction(ctx)
+      }
+      Error(code, msg) -> Error(code, msg)
+    }
+  }
+  Error(code, msg) -> Error(code, msg)
+}
+```
+
+### Pattern 2: PDA Usage
+
+```gleam
+// Generate a PDA
+let seeds = [[1, 2, 3], [4, 5, 6]]
+let pda = anchor.find_program_address(seeds, program_id)
+
+// Use the PDA address
+let pda_account = AccountInfo(
+  key: pda.address,
+  lamports: 0,
+  data: [],
+  owner: program_id,
+  is_signer: False,
+  is_writable: True,
+)
+```
+
+### Pattern 3: Error Handling
+
+```gleam
+case process_instruction(program_id, accounts, instruction_data) {
+  Success(result) -> {
+    // Success! Return 0 exit code
+    anchor.to_exit_code(Success(result))
+  }
+  Error(anchor.InvalidInstruction, msg) -> {
+    // Handle invalid instruction
+    log_error(msg)
+    anchor.to_exit_code(Error(anchor.InvalidInstruction, msg))
+  }
+  Error(code, msg) -> {
+    // Handle other errors
+    log_error(msg)
+    anchor.to_exit_code(Error(code, msg))
+  }
+}
+```
+
+### Pattern 4: State Management
+
+```gleam
+pub type GameState {
+  GameState(
+    players: List(Int),
+    score: Int,
+    round: Int,
+    is_active: Bool,
+  )
+}
+
+pub fn initialize_game(ctx: Context) -> ProgramResult(GameState) {
+  // ... validate accounts ...
+  Success(GameState(
+    players: [],
+    score: 0,
+    round: 1,
+    is_active: True,
+  ))
+}
+
+pub fn add_player(ctx: Context, state: GameState, player_id: Int) -> ProgramResult(GameState) {
+  // ... validate accounts ...
+  let new_players = [player_id, ..state.players]
+  Success(GameState(..state, players: new_players))
+}
+```
+
+## Next Steps
+
+1. **Read the full documentation** - [ANCHOR_FRAMEWORK.md](ANCHOR_FRAMEWORK.md)
+2. **Study the counter example** - `src/counter.gleam`
+3. **Review the tests** - `test/anchor_test.gleam`
+4. **Explore LiteSVM tests** - `litesvm_tests/tests/integration_test.rs`
+5. **Build your own program** - Start with a simple state machine
+
+## Common Issues
+
+### Issue: "Account not found at index"
+
+**Solution**: Make sure you're passing the correct number of accounts and accessing the right index.
+
+```gleam
+// Wrong: Only 2 accounts but accessing index 2
+let ctx = Context(999, [account1, account2], [])
+anchor.get_account(ctx, 2)  // Error!
+
+// Right: Access existing indices
+anchor.get_account(ctx, 0)  // account1
+anchor.get_account(ctx, 1)  // account2
+```
+
+### Issue: "Account must be a signer"
+
+**Solution**: Ensure the account's `is_signer` field is `True`:
+
+```gleam
+let account = AccountInfo(
+  key: 123,
+  lamports: 1_000_000,
+  data: [],
+  owner: 0,
+  is_signer: True,  // Must be True for Signer constraint
+  is_writable: False,
+)
+```
+
+### Issue: "Account must be writable"
+
+**Solution**: Ensure the account's `is_writable` field is `True`:
+
+```gleam
+let account = AccountInfo(
+  key: 123,
+  lamports: 1_000_000,
+  data: [],
+  owner: 0,
+  is_signer: False,
+  is_writable: True,  // Must be True for Writable constraint
+)
+```

+
+### Basic Example
+
+```gleam
+import gleamsvm/vm
+import gleamsvm/security
+import gleamsvm/test_utils
+
+pub fn main() {
+  // Create a new VM instance
+  let vm_state = vm.new()
+  
+  // Fund an account
+  let vm_with_account = case vm.airdrop(vm_state, 123, 1_000_000_000) {
+    security.Ok(vm) -> vm
+    security.Error(err) -> {
+      // Handle error
+      vm_state
+    }
+  }
+  
+  // Add a program
+  let program_data = [0x7F, 0x45, 0x4C, 0x46, ..] // ELF data
+  let vm_with_program = case vm.add_program(vm_with_account, 999, program_data) {
+    security.Ok(vm) -> vm
+    security.Error(err) -> vm_with_account
+  }
+  
+  // Create and execute a transaction
+  let accounts = [
+    test_utils.create_test_account(123, 1_000_000_000, True, True)
+  ]
+  let instructions = [
+    test_utils.create_test_instruction(999, [0], [0])
+  ]

+
+## Comparison: GleamSVM vs LiteSVM
+
+| Feature | LiteSVM | GleamSVM |
+|---------|---------|----------|
+| **Language** | Rust | Gleam |
+| **Security Checks** | ~2 basic validations | 20+ comprehensive checks |
+| **Account Validation** | Basic | Owner, Signer, Writable, Executable, Balance, Rent |
+| **Transaction Security** | Minimal | Replay protection, Nonce validation, Fee validation |
+| **Integer Safety** | Rust's built-in | Explicit overflow checks |
+| **Call Depth Limiting** | No | Yes (configurable) |
+| **Instruction Limiting** | No | Yes (200K default) |
+| **Code Integrity** | No | Hash verification |
+| **Type Safety** | Rust types | Gleam types |
+| **Error Messages** | Good | Detailed with error codes |
+| **Customization** | Limited | Highly extensible |
+
+## Security Error Codes
+
+All security violations return detailed error codes:
+
+- **1001-1006**: Account security errors
+- **1007-1010**: Data validation errors
+- **1011-1015**: Transaction security errors
+- **1016-1020**: Program security errors
+- **1021-1025**: Execution limit errors
+
+## Performance
+
+While GleamSVM prioritizes security over raw speed, it's still highly efficient:
+
+- Account validation: < 1ms
+- Transaction execution: 1-10ms (depending on complexity)
+- Memory usage: Minimal (in-memory state)
+
+## Extending GleamSVM
+
+Add custom security checks:
+
+```gleam
+pub fn validate_custom_rule(account: Account) -> SecurityCheckResult {
+  case account.lamports > 1_000_000 && account.is_signer {
+    True -> Passed
+    False -> Failed("Custom validation failed", 2001)
+  }
+}
+```
+
+## Modules
+
+- `gleamsvm/security` - Security validation functions and types
+- `gleamsvm/vm` - Core VM implementation
+- `gleamsvm/test_utils` - Testing utilities and helpers
+
+## Best Practices

+import gleamsvm/security
+import anchor
+
+// Use Anchor types with GleamSVM
+let account = anchor.AccountInfo(...)
+
+// Validate with GleamSVM security
+case security.validate_account_operation(
+  account,
+  True,              // is_write
+  Some(999),         // expected_owner
+  Some(1_000_000)    // min_balance
+) {
+  security.Ok(_) -> // Safe to proceed
+  security.Error(err) -> // Handle security violation
+}
+```

+- escrow_simple.so
+- escrow_validation.so
+- escrow_refund.so
+- And 10+ example programs
+
+## Key Features
+
+### Type Safety
+Full Gleam type system ensures correctness at compile time:
+```gleam
+pub type AccountInfo {
+  AccountInfo(
+    key: Int,
+    lamports: Int,
+    data: List(Int),
+    owner: Int,
+    is_signer: Bool,
+    is_writable: Bool,
+  )
+}
+```
+
+### Account Validation
+Declarative constraint-based validation:
+```gleam
+anchor.validate_account(account, [Signer, Writable, Owner(program_id)])
+```
+
+### Error Handling
+Comprehensive error types matching Solana:
+```gleam
+pub type ErrorCode {
+  InvalidInstruction
+  InvalidAccountData
+  AccountNotSigner
+  AccountNotWritable
+  InsufficientFunds
+  // ... and more
+}
+```
+
+### Instruction Dispatch
+Clean pattern matching for instruction routing:
+```gleam
+case anchor.deserialize_instruction(instruction_data) {
+  Success(0) -> process_initialize(ctx)
+  Success(1) -> process_increment(ctx)
+  _ -> Error(InvalidInstruction, "Unknown instruction")
+}
+```

+
+## Installation
+
+### Step 1: Clone the Repository
+
+```bash
+git clone https://github.com/openSVM/gleam-sbpf.git
+cd gleam-sbpf
+```
+
+### Step 2: Build the Project
+

+
+Expected output:
+```
+100+ tests passed, no failures
+```
+
+### Step 4: Verify Installation
+
+```bash
+gleam run
+```
+
+This compiles example programs and generates `.so` files.
+
+## Your First Gleam Program
+
+Let's build a simple "Hello Solana" program using the Gleam compiler.
+
+### Create a Simple Program
+
+Create a new file `src/hello_solana.gleam`:
+
+```gleam
+import compiler.{type Expression, IntLiteral, Return}
+
+pub fn main() {
+  // Return 42 as the program result
+  let program = Return(IntLiteral(42))
+  
+  // Compile to Solana BPF
+  case compiler.compile_to_elf(program) {
+    compiler.Ok(bytecode) -> {
+      // Success! Program compiled
+      bytecode
+    }
+    compiler.Error(msg) -> {
+      // Handle compilation error
+      []
+    }
+  }
+}
+```
+
+### Compile the Program
+
+```bash
+gleam run -m hello_solana
+```
+
+This generates `hello_solana.so` - a valid Solana BPF program.
+
+### Verify the Output
+
+```bash
+# Check file type
+file hello_solana.so
+# Output: ELF 64-bit LSB shared object, eBPF
+
+# Check ELF headers
+readelf -h hello_solana.so
+# Shows: Type: DYN, Machine: eBPF, Flags: 0x2 (SBPF v2)
+```
+
+## Understanding the Anchor Framework
+
+The Gleam Anchor framework provides structured Solana program development.
+
+### Core Concepts
+
+#### 1. Account Validation
+
+Accounts in Solana must be validated before use:
+
+```gleam
+import anchor.{type AccountInfo, Signer, Writable}
+
+pub fn validate_accounts(account: AccountInfo) {
+  // Ensure account is both a signer and writable
+  anchor.validate_account(account, [Signer, Writable])
+}
+```
+
+#### 2. Program Context
+
+Every program receives a context with accounts and instruction data:
+
+```gleam
+import anchor.{type Context}
+
+pub fn process(ctx: Context) {
+  // Get first account
+  case anchor.get_account(ctx, 0) {
+    Success(account) -> // Use account
+    Error(code, msg) -> // Handle error
+  }
+}
+```
+
+#### 3. Error Handling
+
+All operations return `ProgramResult`:
+
+```gleam
+pub type ProgramResult(a) {
+  Success(a)
+  Error(code: ErrorCode, message: String)
+}
+```
+
+### Building a Counter Program
+
+Let's build a complete counter program step by step.
+
+#### Step 1: Define State
+
+```gleam
+pub type CounterState {
+  CounterState(
+    authority: Int,
+    count: Int,
+  )
+}
+```
+
+#### Step 2: Initialize Function
+
+```gleam
+pub fn initialize(ctx: Context) -> ProgramResult(CounterState) {
+  case anchor.get_account(ctx, 0) {
+    Success(counter) -> {
+      case anchor.get_account(ctx, 1) {
+        Success(authority) -> {
+          case anchor.validate_account(authority, [Signer]) {
+            Success(_) -> {
+              Success(CounterState(
+                authority: authority.key,
+                count: 0,
+              ))
+            }
+            Error(code, msg) -> Error(code, msg)
+          }
+        }
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+```
+
+#### Step 3: Increment Function
+
+```gleam
+pub fn increment(ctx: Context, current: Int) -> ProgramResult(Int) {
+  case anchor.get_account(ctx, 0) {
+    Success(counter) -> {
+      case anchor.validate_account(counter, [Writable]) {
+        Success(_) -> Success(current + 1)
+        Error(code, msg) -> Error(code, msg)
+      }
+    }
+    Error(code, msg) -> Error(code, msg)
+  }
+}
+```
+
+See [src/counter.gleam](src/counter.gleam) for the complete implementation.
+
+## Testing with GleamSVM
+
+GleamSVM provides comprehensive testing for Solana programs.
+
+### Unit Testing
+
+Create `test/my_program_test.gleam`:
+
+```gleam
+import gleamsvm/vm
+import gleamsvm/test_utils
+import gleeunit/should
+
+pub fn test_account_creation() {
+  // Create VM
+  let vm_state = vm.new()
+  
+  // Airdrop lamports
+  let result = vm.airdrop(vm_state, 123, 1_000_000)
+  
+  // Verify success
+  case result {
+    Ok(vm) -> should.be_true(True)
+    Error(_) -> should.fail()
+  }
+}
+```
+
+Run tests:
+
+```bash
+gleam test
+```
+
+### Integration Testing with LiteSVM
+
+LiteSVM provides fast, in-memory Solana VM testing (100x faster than test validator).
+
+```bash
+cd litesvm_tests
+cargo test --release
+```
+
+Benefits:
+- Fast: Tests run in milliseconds
+- Isolated: Each test gets a fresh VM
+- Deterministic: No network or timing issues
+- CI-friendly: Runs in constrained environments
+
+See [LITESVM_TESTING.md](LITESVM_TESTING.md) for complete guide.
+
+## Deployment to Solana
+
+### Step 1: Configure Solana CLI
+
+```bash
+# Set cluster (devnet for testing)
+solana config set --url https://api.devnet.solana.com
+
+# Create a wallet (if you don't have one)
+solana-keygen new --outfile ~/.config/solana/id.json
+
+# Check balance
+solana balance
+```
+
+### Step 2: Airdrop SOL (Devnet only)
+
+```bash
+solana airdrop 2
+```
+
+### Step 3: Deploy Your Program
+
+```bash
+solana program deploy hello_solana.so
+```
+
+Output:
+```
+Program Id: <YOUR_PROGRAM_ID>
+```
+
+### Step 4: Verify Deployment
+
+```bash
+solana program show <YOUR_PROGRAM_ID>

+
+## Usage
+
+Each example can be studied independently. Navigate to any example directory and check its README for details:
+
+```bash
+cd anchor_examples/example_01
+cat README.md
+```
+
+## Learning Path
+
+We recommend studying the examples in order:
+
+1. **Start with Examples 1-5** to understand basic account validation and constraints
+2. **Continue with Examples 6-10** to learn about state management and instruction handling
+3. **Study Examples 11-20** for intermediate patterns and best practices
+4. **Finish with Examples 21-25** to see complete program patterns
+
+## Building Examples
+
+While these examples are primarily for learning, you can reference them when building your own programs:
+
+```gleam
+import anchor.{type Context, type ProgramResult, Success, Error, Signer}
+
+// Use patterns from the examples
+pub fn my_function(ctx: Context) -> ProgramResult(Int) {
+  // Your code here
+  Success(42)
+}
+```
+
