 TypeScript library for MeshCore protocol utilities.
 
-Quick start
+## Packet parsing
 
-1. Install dev dependencies:
+Using the library to decode MeshCore packets:
 
-```bash
-npm install --save-dev typescript tsup
+```ts
+import { Packet } from '@hamradio/meshcore';
+
+const raw = new Uint8Array(Buffer.from("050AA50E2CB0336DB67BBF78928A3BB9BF7A8B677C83B6EC0716F9DD10002A06", "hex"));
+const packet = Packet.fromBytes(raw);
+console.log(packet);
+
+/*
+_Packet {
+  header: 5,
+  transport: undefined,
+  pathLength: 10,
+  path: Uint8Array(10) [
+    165,  14,  44, 176,
+     51, 109, 182, 123,
+    191, 120
+  ],
+  payload: Uint8Array(20) [
+    146, 138,  59, 185, 191, 122,
+    139, 103, 124, 131, 182, 236,
+      7,  22, 249, 221,  16,   0,
+     42,   6
+  ],
+  routeType: 1,
+  payloadVersion: 0,
+  payloadType: 1,
+  pathHashCount: 10,
+  pathHashSize: 1,
+  pathHashBytes: 10,
+  pathHashes: [
+    'a5', '0e', '2c',
+    'b0', '33', '6d',
+    'b6', '7b', 'bf',
+    '78'
+  ]
+}
+*/
 ```
 
-2. Build the library:
+## Identities
 
-```bash
-npm run build
-```
-
-3. Use the build output from the `dist/` folder or publish to npm.
+The package supports:
+- `Identity` for public key management.
+- `LocalIdentity` for private key management.
+- `Contact` for managing named identities.
+- `Group` for managing groups.
+- `KeyManager` for managing all of the above and handling decryption.
