+
+### Port mapping
 
 If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used. Just add `-p 8080:9000` to the `docker run` arguments and then access either `http://localhost:8080` or `http://host-ip:8080` in a browser.

 ```
+
+## Environment variables
+
+When you start the `%%REPO%%` image, you can adjust the configuration of the Sentry instance by passing one or more environment variables on the `docker run` command line. Please note that these environment variables are provided as a jump start, and it's highly recommended to either mount in your own config file or utilize the `%%REPO%%:onbuild` variant.
+
+### `SENTRY_SECRET_KEY`
+
+A secret key used for cryptographic functions within Sentry. This key should be unique and consistent across all running instances. You can generate a new secret key doing something like:
+
+```console
+$ docker run --rm -it debian:jessie cat /proc/sys/kernel/random/uuid
+```
+
+### `SENTRY_POSTGRES_HOST`, `SENTRY_POSTGRES_PORT`, `SENTRY_DB_NAME`, `SENTRY_DB_USER`, `SENTRY_DB_PASSWORD`
+
+Database credentials for your Postgres server. These values aren't needed if a linked `postgres` container exists.
+
+### `SENTRY_REDIS_HOST`, `SENTRY_REDIS_PORT`, `SENTRY_REDIS_DB`
+
+Connection information for your Redis server. These values aren't needed if a linked `redis` container exists.
+
+### `SENTRY_MEMCACHED_HOST`, `SENTRY_MEMCACHED_PORT`
+
+Connection information for a Memcache server. These values aren't needed if a linked `memcached` container exists.
+
+### `SENTRY_FILESTORE_DIR`
+
+Directory where uploaded files will be stored. This defaults to `/var/lib/sentry/files` and is a `VOLUME` for persistent data.
+
+### `SENTRY_SERVER_EMAIL`
+
+The email address used for `From:` in outbound emails. Default: `root@localhost`
+
+### `SENTRY_EMAIL_HOST`, `SENTRY_EMAIL_PORT`, `SENTRY_EMAIL_USER`, `SENTRY_EMAIL_PASSWORD`, `SENTRY_EMAIL_USE_TLS`
+
+Connection information for an outbound smtp server. These values aren't needed if a linked `smtp` container exists.
+
+### `SENTRY_MAILGUN_API_KEY`
+
+If you're using Mailgun for inbound mail, set your API key and configure a route to forward to `/api/hooks/mailgun/inbound/`.

+## `%%REPO%%:onbuild`
+
+This image makes it easy to custom build your own Sentry instance by copying in a custom `config.yml` and/or `sentry.conf.py` file and installing plugins from `requirements.txt`.
+
+It's also possible to develop custom extensions within your `onbuild` package. If the build directory contains a `setup.py` file, this will also get installed.
+
+See the [official Sentry documentation](https://docs.getsentry.com/on-premise/server/installation/) for more information.
