 Dagger is a tool that's used for building the project.
 The `.dagger` directory and the `dagger.json` file contain most of the configuration.
 Install the Dagger CLI from [here](https://docs.dagger.io/install/) and run the `dagger` command in the root of the project.
-Then you can run the commands from the `.dagger/src/index.ts` file, e.g. `dagger call build-browser`.
-Add `-i` to the command to run in interactive mode, add `--output` to save the output to a folder.

+If you want to output artifacts (e.g. binaries), use:
+`dagger call --interactive release-assets export --pa

 You can pass secrets / ENVS to dagger like so:
 `dagger call typedoc-publish --netlify-auth-token="env://NETLIFY_AUTH_TOKEN"`

 Note that the camelCase functions in the `index.ts` file are converted to kebab-case commands in the Dagger API.
