+
+## Testing
+
+This project is tested using [Vitest](https://vitest.dev). There are two kinds of tests.
+
+### Unit tests
+
+Unit tests are in the [`test/unit`](test/unit) folder of the project. You can run them using the following command:
+
+```sh
+yarn vitest test/unit
+```
+
+### Integration tests
+
+Integration tests are in the [`test/integration`](test/integration) folder. They require some extra setup.
+
+Firstly, these tests require the Cloudflare executable. You can download this with:
+
+```sh
+curl -fsSLo cloudflared-linux-amd64 https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64
+chmod +x cloudflared-linux-amd64
+```
+
+They also require a Transloadit key and secret, which you can get from https://transloadit.com/c/credentials.
+
+You can run the integration tests with:
+
+```sh
+TRANSLOADIT_KEY='YOUR_TRANSLOADIT_KEY' TRANSLOADIT_SECRET='YOUR_TRANSLOADIT_SECRET' CLOUDFLARED_PATH='./cloudflared-linux-amd64' vitest run test/integration
+```
+
+## Releasing
+
+Only maintainers can make releases. Releases to [npm](https://www.npmjs.com) are automated using GitHub actions. To make a release, perform the following steps:
+
+1. Update the version using Yarn, e.g. `yarn version patch`. This will create a new Git commit and tag.
+2. Push the tag to GitHub.
+   ```sh
+   git push origin main --tags
+   ```
+3. If the tests pass, GitHub actions will now publish the new version to npm.
+4. When successful add [release notes](https://github.com/transloadit/node-sdk/releases).
