+# Bounty Submission: SoroSave SDK CLI Tool (Issue #36)
+
+**Bounty Issue:** https://github.com/sorosave-protocol/sdk/issues/36  
+
+## What I built
+
+A complete **Node.js CLI tool** built with `Commander.js` that allows users to interact with the SoroSave protocol directly from their terminal.
+
+### Commands Implemented
+- `create-group`: Initialize a new savings group on-chain.
+- `join-group`: Participate in an existing group.
+- `contribute`: Submit contributions for the current round.
+- `get-group`: Fetch detailed group status and metadata.
+- `list-groups`: List all groups a specific public key is participating in.
+
+### Technical Highlights
+- **Stellar SDK Integration**: Seamless handling of keys, networks (Testnet/Mainnet), and transaction signing.
+- **Flexible Output**: Supports both human-readable text and machine-readable JSON (via `--json`).
+- **Configuration**: Uses environment variables (`SOROSAVE_SECRET`, `SOROSAVE_CONTRACT_ID`) or CLI flags for easy automation.
+
+### Installation
+```bash
+npm link
+```
+
+### Usage Examples
+```bash
+# Create a group
+sorosave create-group "Tech Savings" "TOKEN_ADDRESS" 1000 86400 5 --secret S...
+
+# Get group info in JSON
+sorosave get-group 1 --json
+```
+
+## Reviewer requirements checklist
+
+1) **Add CLI entry point using commander or yargs** ✅
+- Implemented in `src/cli.ts` using `commander`.
+
+2) **Commands: create-group, join-group, contribute, get-group, list-groups** ✅
+- All core protocol interactions mapped to CLI commands.
+
+3) **Package bin configuration** ✅
+- Added `"bin": { "sorosave": "./dist/cli.js" }` to `package.json`.
