+Drupal Application Container
+============================
+
+These [Dockerfiles](https://docs.docker.com/engine/reference/builder/) define the [massgov/drupal-container](https://hub.docker.com/r/massgov/drupal-container) images.  These images are automatically built by Docker Hub.
+
+Variants
+--------
+The variants of this image are:
+  [`ci`](./ci/) - An image appropriate for use in continuous integration environments.  Closely mirrors Acquia's application servers, except that mail is disabled.
+  [`dev`](./dev/) - An image appropriate for use in development environments.  Adds Xdebug, Blackfire, ...
+
+Environment variables
+------------------
+1. XDEBUG_ENABLE: Adds xdebug extension which is configured to autostart (assumes Docker for Mac).
+
+Making changes
+--------------
+
+1. Make changes to the Dockerfile for the desired variant.
+2. Test changes by building the image locally using `docker-compose build`
+3. Note changes in [CHANGELOG.txt](./CHANGELOG.txt).
+4. Commit and push changes to this repository: 
+    ```
+    git commit -m "My message"
+    git push origin master
+    ```
+5. Optionally, tag a new release:
+    ```bash
+    git tag 1.0.0
+    git push origin 1.0.0
+    ```
+    When you tag a release, you should also update your code to use the new version as soon as it's available.  You can check on the availability on the [build details](https://hub.docker.com/r/massgov/drupal-container/builds/) page.
+
+Changes that are pushed to the `master` branch are built automatically by Docker hub.  For example, a change pushed to master affecting the `ci` variant would update `massgov/drupal-container:ci`.  Tags are also built automatically and create a new tagged version of the image.  For example, a new tag `4.1.0` would create new versions of all variants, which would be available using `massgov/drupal-container:4.1.0-ci` etc.
