+Run chantry's Twilight Struggle server in Docker. Very nice!
+
+# Setup
+
+Clone the `chantry-website` and `chantry-ts` repos from https://bitbucket.org/arry/chantry-website.
+
+## Bugfix
+
+You may have to make a small modification to `chantry-website/main/lib/Chantry/WebApp.pm`
+and `chantry-website/main/templates/games/play.html.tt` if you're unable to
+load the `ts` module in the browser. Find these lines and change `${game_code}.js`
+to `${game_code}_bundle.js`:
+
+```
+# chantry-website/main/lib/Chantry/WebApp.pm
+$self->asset("${game_code}.js" => (
+
+# chantry-website/main/templates/games/play.html.tt
+[% additional_page_js = "${game_code}.js" %]
+```
+
+# Local hacking
+
+`docker-compose build && docker-compose up`.
+
+# Deploying
+
+`REPO=your.docker.registry ./docker-build` will build the app and Perl/PostgreSQL
+container, push the app container to the registry, and export the data container
+to a `.tar.bz2` file. You can then use the Ansible playbook to do the deploy to
+a remote Docker host:
+
+```
+REPO=your.docker.registry \
+EXTERNAL_HOST=www.deployed.location \
+EXTERNAL_PORT=45678 \
+ansible-playbook playbook.yml -e with_perl=1 -i hosts
+```
+
+Set `with_perl=0` to not push a new Perl/PostgreSQL data container.
+
+## Adding users
+
+Generate passwords with `docker exec -i chantry create_pw $password`.
+Add them to a SQL file (let's say `users.sql`) with this format:
+
+``` sql
+INSERT INTO chantry.users (username, password_hash, email)
+VALUES ('john', 'password-from-create_pw', 'john@example.com');
+```
+
+Pipe that file into PostgreSQL:
+
+`docker exec -i chantry add_users < ./users.sql`
+
