+### SQLite Local Setup (Easiest)
+
+You can use SQLite for local development. This is the easiest way to get started with bgent.
+
+```typescript
+import { BgentRuntime, SqliteDatabaseAdapter } from "bgent";
+import { Database } from "sqlite3";
+const sqliteDatabaseAdapter = new SqliteDatabaseAdapter(new Database(":memory:"));
+
+const runtime = new BgentRuntime({
+  serverUrl: "https://api.openai.com/v1",
+  token: process.env.OPENAI_API_KEY, // Can be an API key or JWT token for your AI services
+  databaseAdapter: sqliteDatabaseAdapter,
+  // ... other options
+});
+```
