+# API Service
+
+## Overview
+
+The API service is responsible for serving custom Bluesky feeds to clients. It implements the necessary endpoints required by the Bluesky protocol to deliver feed content.
+
+**Pre-Built Docker Image**: `git.aykhans.me/bsky/feedgen-api:latest`
+
+## API Endpoints
+
+- `GET /.well-known/did.json`: DID configuration
+- `GET /xrpc/app.bsky.feed.describeFeedGenerator`: Describe the feed generator
+- `GET /xrpc/app.bsky.feed.getFeedSkeleton`: Main feed endpoint
+
+## Running the Service
+
+### Docker
+
+```bash
+docker build -f cmd/api/Dockerfile -t bsky-feedgen-api .
+docker run --env-file config/app/.api.env --env-file config/app/.mongodb.env -p 8421:8421 bsky-feedgen-api
+```
+
+### Local Development
+
+```bash
+task run-api
+# or
+make run-api
+```
