+# Universal Resolver Driver: did:cid
+
+A [Universal Resolver](https://github.com/decentralized-identity/universal-resolver) driver for the **did:cid** method used by [Archon Protocol](https://archetech.com).
+
+## About did:cid
+
+`did:cid` is a content-addressed DID method where the DID identifier is derived from the IPFS CID of the initial DID document. This provides:
+
+- **Instant creation** — No blockchain transaction required
+- **Self-certifying** — The DID proves its own integrity
+- **Multi-registry** — Updates can be anchored to various registries (Hyperswarm, Bitcoin, etc.)
+
+## Specifications
+
+- DID Method: `did:cid`
+- [DID Specification](https://github.com/nickthetj/archon-protocol/blob/main/docs/did-cid-spec.md)
+- [Archon Protocol](https://archetech.com)
+
+## Example DIDs
+
+```
+did:cid:bagaaieraxdxq4fm2kjh6yqjxjor3t2idczkmxd4v7in4u353fa6m6sms2pnq
+did:cid:bagaaierajzwcicueqdkbgk75lgekdmvtbo5zv3spq2p4f7d7ow42urlwi32a
+```
+
+## Running Locally
+
+```bash
+# Install dependencies
+npm install
+
+# Start the driver
+PORT=4250 ARCHON_GATEKEEPER_URL=http://localhost:4224 npm start
+
+# Test resolution
+curl http://localhost:4250/1.0/identifiers/did:cid:bagaaieraxdxq4fm2kjh6yqjxjor3t2idczkmxd4v7in4u353fa6m6sms2pnq
+```
+
+## Docker
+
+```bash
+# Build
+docker build -t archetech/uni-resolver-driver-did-cid:0.1.0 .
+
+# Run
+docker run -p 4250:4250 -e ARCHON_GATEKEEPER_URL=http://host.docker.internal:4224 archetech/uni-resolver-driver-did-cid:0.1.0
+
+# Test
+curl http://localhost:4250/1.0/identifiers/did:cid:bagaaieraxdxq4fm2kjh6yqjxjor3t2idczkmxd4v7in4u353fa6m6sms2pnq
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `4250` | Port to listen on |
+| `GATEKEEPER_URL` | `https://gatekeeper.archon.technology` | Archon gatekeeper endpoint |
+
+## API Endpoints
+
+| Endpoint | Description |
+|----------|-------------|
+| `GET /1.0/identifiers/{did}` | Resolve a did:cid |
+| `GET /1.0/methods` | List supported methods (`["cid"]`) |
+| `GET /health` | Health check |
+
+## Integration with Universal Resolver
+
+Add to `docker-compose.yml`:
+
+```yaml
+driver-did-cid:
+  image: archetech/uni-resolver-driver-did-cid:0.1.0
+  ports:
+    - "4250:4250"
+  environment:
+    - ARCHON_GATEKEEPER_URL=http://your-gatekeeper:4224
+```
+
+Add to `application.yml`:
+
+```yaml
+- pattern: "^(did:cid:.+)$"
+  url: "${uniresolver_web_driver_url_did_cid:http://driver-did-cid:4250/1.0/identifiers/}"
+  testIdentifiers:
+    - "did:cid:bagaaieraxdxq4fm2kjh6yqjxjor3t2idczkmxd4v7in4u353fa6m6sms2pnq"
+    - "did:cid:bagaaierajzwcicueqdkbgk75lgekdmvtbo5zv3spq2p4f7d7ow42urlwi32a"
