+
+![Ruby](https://github.com/ryanwi/rails7-on-docker/workflows/Ruby/badge.svg)
+
+This app demonstrates Rails 7 with PostgreSQL, import maps, turbo, stimulus and hotwire, all running in Docker.
+
+## Initial setup
+```
+docker compose build
+docker compose run --rm web bin/rails db:setup
+```
+
+## Running the Rails app
+```
+docker compose up
+```
+
+## Running the Rails console
+When the app is already running with `docker-compose` up, attach to the container:
+```
+docker compose exec web bin/rails c
+```
+
+When no container running yet, start up a new one:
+```
+docker compose run --rm web bin/rails c
+```
+
+## Running tests
+```
+docker compose run --rm web bundle exec rspec
+```
+
+## Updating gems
+```
+docker compose run --rm web bundle update
+docker compose up --build
+```
