+# Shuttle Development Rules
+
+## Core Setup
+
+Always use `#[shuttle_runtime::main]` as your entry point. Can be other frameworks too, you can use the Shuttle MCP - search docs tool to find the correct code for your framework.
+
+```rust
+#[shuttle_runtime::main]
+async fn main() -> ShuttleAxum {
+    let router = Router::new().route("/", get(hello));
+    Ok(router.into())
+}
+```
+
+## Databases
+
+- **Shared DB** (free): `#[shuttle_shared_db::Postgres] pool: PgPool`
+- **AWS RDS** (paid): `#[shuttle_aws_rds::Postgres] pool: PgPool`
+
+## Secrets
+
+Create `Secrets.toml` in project root, add to `.gitignore`:
+
+```toml
+MY_API_KEY = 'your-api-key-here'
+```
+
+Use in code:
+
+```rust
+#[shuttle_runtime::main]
+async fn main(#[shuttle_runtime::Secrets] secrets: SecretStore) -> ShuttleAxum {
+    let api_key = secrets.get("MY_API_KEY").unwrap();
+    Ok(router.into())
+}
+```
+
+## Static Assets
+
+Configure in `Shuttle.toml`:
+
+```toml
+[build]
+assets = [
+    "assets/*",
+    "frontend/dist/*",
+    "static/*"
+]
+
+[deploy]
+include = ["ignored-files/*"]  # Include files that are normally ignored by git
+deny_dirty = true
+```
+
+## Development Workflow
+
+1. `shuttle run` - local development
+2. Use MCP server for AI-assisted development
+3. Use MCP server for Searching the Docs
+
+## Key Points
+
+- Always use `#[shuttle_runtime::main]` as your entry point
+- Configure static assets in `Shuttle.toml`
+- Use secrets for sensitive configuration
