+# Port From Project Name
+
+A Raycast extension that generates unique 4-digit ports for your development projects based on the project name.
+
+## Features
+
+- **Deterministic Port Generation**: Same project name always generates the same port
+- **Port History**: Keeps track of all generated ports with timestamps
+- **Quick Access**: Generate ports directly from Raycast with a simple command
+- **History Management**: View, search, and manage your port history
+
+## Installation
+
+1. Install the extension from the Raycast Store
+2. No additional setup or configuration required
+
+## Usage
+
+### Generate Port
+
+Use the "Generate port" command in Raycast:
+
+1. Open Raycast
+2. Type "Generate port"
+3. Enter your project name as an argument
+4. The extension will generate and display a unique port for that project
+
+**Example:**
+```
+Generate port my-react-app
+```
+This will generate a consistent port number for the "my-react-app" project.
+
+### View Port History
+
+Use the "Port History" command to:
+
+- View all previously generated ports
+- See when each port was first created and last updated
+- Search through your port history
+- Copy port numbers to clipboard
+- Delete individual entries or clear all history
+
+## How It Works
+
+The extension uses a deterministic algorithm to generate ports:
+
+1. Creates an MD5 hash of the project name
+2. Converts the first 8 characters of the hash to an integer
+3. Maps the result to a port number in the range 1000-9999
+4. Stores the mapping in local history for future reference
+
+**Port Range:** 1000-9999 (4-digit ports commonly used for development)
+
+## Important Notes
+
+- **Deterministic**: The same project name always generates the same port
+- **Collision possibility**: Different project names may occasionally generate the same port. With 9,000 possible ports (1000-9999), collisions are rare but possible in practice (~42% collision probability with 100 projects).
+
+## Privacy
+
+- All data is stored locally on your device
+- No information is sent to external servers
+- Project names and generated ports are only used locally
+
+## Development
+
+This extension is built with:
+- TypeScript
+- Raycast API
+- React hooks for state management
+- Local storage for history persistence
