+# @_koii/k2-port
+
+## Project Overview
+
+`@_koii/k2-port` is a TypeScript library for generating and submitting Proof of Rendering Time (PoRT) data to the KOII network. This library provides developers with a streamlined way to interact with KOII's decentralized infrastructure, specifically for the Attention Game mechanism.
+
+### Key Features
+- Generate cryptographically signed Port data
+- Submit PoRT to multiple KOII network nodes
+- Automatic wallet key management
+- Flexible configuration for node interactions
+- Support for browser and Node.js environments
+
+### Use Cases
+- Decentralized content verification
+- Tracking content rendering and engagement
+- Generating proof of content interaction
+
+## Installation
+
+Install the library using npm or yarn:
+
+```bash
+npm install @_koii/k2-port
+# or
+yarn add @_koii/k2-port
+```
+
+### Prerequisites
+- Node.js (v14 or higher)
+- TypeScript (recommended)
+- A compatible browser with localStorage support (for browser environments)
+
+## API Reference
+
+### `PoRT` Class
+
+#### Constructor
+```typescript
+constructor(initParams?: InitParams)
+```
+
+**Initialization Parameters**:
+- `trustedNodeAddress` (optional): URL to a trusted KOII node. 
+  - Default: `"https://k2-tasknet.koii.live"`
+- `propagationCount` (optional): Number of nodes to send PoRT to.
+  - Default: `3`
+- `namespaceId` (optional): Namespace identifier.
+  - Default: `"Attention"`
+- `walletLocation` (optional): Key for wallet storage in localStorage.
+  - Default: `"k2-wallet"`
+- `ignoreRejection` (optional): Whether to ignore connection rejections.
+  - Default: `false`
+- `connectionWait` (optional): Wait for connection before sending anonymous PoRTs.
+  - Default: `false`
+
+#### Methods
+
+##### `propagatePoRT(id: string)`
+Submit Proof of Rendering Time for a specific content ID.
+
+**Parameters**:
+- `id`: A string representing the content identifier
+
+**Returns**: 
+- Submits PoRT to multiple KOII network nodes
+
+**Example**:
+```typescript
+const port = new PoRT();
+await port.propagatePoRT("your-content-id");
+```
+
+##### `signPort(id: string)`
+Generate signed Port headers for a given content ID.
+
+**Parameters**:
+- `id`: A string representing the content identifier
+
+**Returns**:
+- `PoRTData`: Signed message and public key
