 Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/xlsx_writer_wrapper`. To experiment with that code, run `bin/console` for an interactive prompt.
 
 TODO: Delete this and the text above, and describe your gem
+## 👩🏾‍💻 Setup - Docker
+
+1. Ensure you have desktop `docker` installed or install it with `brew install --cask docker`
+2. Create a Github TOKEN in https://github.com/settings/tokens with all "repo" permissions, then add an export for it in your profile specs: `~/.bashrc` or `~/.zshrc` or  🤷🏾‍♀️
+    ```bash
+    export GITHUB_TOKEN=123adf123...
+    ```
+3. Build image: `docker compose build`
+4. Then you can bring up all the services with `docker compose up -d`, this command starts the container APP or `make up`
+6. Launch all specs: `docker compose exec app bundle exec rspec`
+7. Launch console: `docker compose exec app sh`
