+## Testing
+
+* Haskell code is tested with Stack: `stack test`.
+* JavaScript code is linted with `eslint`.
+
+### Integration tests
+
+Integration tests are not run automatically due to the need for an AWS account.
+To run them manually:
+
+* Ensure you have the required dependencies: `curl`, [jq], [NPM] and [Stack].
+* Get an AWS account and add the access credentials into your shell environment.
+* Run `./integration-test/run.sh`. The exit code indicates success.
+
 ## Releasing
 
+* Run the integration tests.
 * Install [bumpversion](https://github.com/peritus/bumpversion): `pip install bumpversion`.
 * Run `bumpversion major|minor|patch`.
 * Run `git push --tags && git push`.
