+#### TypeScript Tests
+
+Type tests are located in [/types/tests.ts](/types/tests.ts) and are responsible for ensuring that the type generation for each class is behaving as expected. Types are generated by manually running the script `npm run build:types`. The generated types are `.d.ts` files located in [/types](/types) and must not be manually changed after generation.
+
+> [!CAUTION]
+> An exemption are type changes to `src/Options/index.js` which must be manually updated in `types/Options/index.d.ts`, as these types are not generated via a script.
+
+When developing type definitions you can run `npm run watch:ts` in order to rebuild your changes automatically upon each save. Use `npm run test:types` in order to run types tests against generated `.d.ts` files.
+
 ### Test against Postgres
 
 If your pull request introduces a change that may affect the storage or retrieval of objects, you may want to make sure it plays nice with Postgres.
