 A Makefile is provided which you can use to build and run the fastly to insights integration locally -- `make run` will build and then run the image. You can provide configuration via a `.env` file (`.env.example` provided as an example).

+To release a new image, make sure you've created a tag for your release, check it out and then run `make release tag=<your-tag>`. This will build the Docker image and push it to DockerHub.
