 `drift_sqlite_async` allows using drift on an sqlite_async database - the APIs from both can be seamlessly used together in the same application.
 
 Supported functionality:
+
 1. All queries including select, insert, update, delete.
 2. Transactions and nested transactions.
 3. Table updates are propagated between sqlite_async and Drift - watching queries works using either API.
 4. Select queries can run concurrently with writes and other select statements.

+Note: Web support is currently in Beta.
+
+Web support requires Sqlite3 WASM and web worker Javascript files to be accessible. These file need to be put into the `web/` directory of your app.
+
+The compiled web worker files can be found in our Github [releases](https://github.com/powersync-ja/sqlite_async.dart/releases)
+The `sqlite3.wasm` asset can be found [here](https://github.com/simolus3/sqlite3.dart/releases)
