+# FalconTS
+
+A TypeScript implementation of the Falcon signature scheme with a custom mnemonic implementation for key management.
+
+## Overview
+
+This project provides a TypeScript implementation of the Falcon signature scheme, along with a custom mnemonic implementation for generating, storing, and recovering Falcon keys using human-readable phrases.
+
+## Features
+
+- Falcon signature scheme implementation
+- Custom mnemonic implementation for Falcon keys
+- Key generation, signing, and verification
+- Mnemonic phrase generation and validation
+- Key recovery from mnemonic phrases
+
+## Installation
+
+```bash
+npm install
+```
+
+## Usage
+
+### Basic Falcon Usage
+
+```typescript
+import { Falcon } from './src/falcon';
+
+// Create a Falcon instance
+const falcon = new Falcon();
+await falcon.init();
+
+// Generate a key pair
+await falcon.genkey();
+
+// Get the key pair
+const keypair = await falcon.getKeypair();
+const publicKey = keypair.pk;
+const privateKey = keypair.sk;
+
+// Sign a message
+const message = 'Hello, Falcon!';
+const signature = await falcon.sign(message);
+
+// Verify the signature
+const isValid = await falcon.verify(message, signature);
+console.log('Signature verification:', isValid ? 'Valid' : 'Invalid');
+```
+
+### Mnemonic Implementation
+
+```typescript
+import { generateMnemonic, mnemonicToUint8Array, uint8ArrayToMnemonic, validateMnemonic } from './src/mnemonic';
+import { Falcon } from './src/falcon';
+
+// Generate a random mnemonic
+const mnemonic = generateMnemonic();
+console.log('Generated mnemonic:', mnemonic);
+
+// Convert mnemonic to seed
+const seed = mnemonicToUint8Array(mnemonic);
+
+// Create a Falcon instance
+const falcon = new Falcon();
+await falcon.init();
+
+// Generate a key pair using the seed
+await falcon.genkey(seed);
+
+// Get the key pair
+const keypair = await falcon.getKeypair();
+const publicKey = keypair.pk;
+const privateKey = keypair.sk;
+
+// Later, recover the keys from the mnemonic
+const recoveredSeed = mnemonicToUint8Array(mnemonic);
+const recoveredFalcon = new Falcon();
+await recoveredFalcon.init();
+await recoveredFalcon.genkey(recoveredSeed);
+const recoveredKeypair = await recoveredFalcon.getKeypair();
+```
+
+## Examples
+
+Run the examples to see the mnemonic implementation in action:
+
+```bash
+# Run the basic example
+npx ts-node src/example.ts
+
+# Run the mnemonic example
+npx ts-node mnemonic_example.ts
+```
+
+## How It Works
+
+### Falcon Signature Scheme
+
+Falcon is a lattice-based signature scheme that offers strong security with relatively small key and signature sizes. This implementation provides a TypeScript interface to the Falcon signature scheme.
+
+### Custom Mnemonic Implementation
+
+The mnemonic implementation converts between binary data (Uint8Array) and human-readable mnemonic phrases. It uses a list of 2048 common English words, with each word representing 11 bits of entropy. A mnemonic phrase consists of 12 words, providing 132 bits of entropy, which is sufficient for Falcon keys.
+
+The implementation includes the following functions:
+
+- `uint8ArrayToMnemonic(data: Uint8Array): string` - Converts a Uint8Array to a mnemonic phrase
+- `mnemonicToUint8Array(mnemonic: string): Uint8Array` - Converts a mnemonic phrase to a Uint8Array
+- `validateMnemonic(mnemonic: string): boolean` - Validates a mnemonic phrase
+- `generateMnemonic(): string` - Generates a random mnemonic phrase
