 # Synapse Docker
 
-The `matrixdotorg/synapse` Docker image will run Synapse as a single process. It does not provide a
-database server or a TURN server, you should run these separately.
-
-If you run a Postgres server, you should simply include it in the same Compose
-project or set the proper environment variables and the image will automatically

-
-## Build
-
-Build the docker image with the `docker-compose build` command.
-
-You may have a local Python wheel cache available, in which case copy the relevant packages in the ``cache/`` directory at the root of the project.
-
-## Run
-
-This image is designed to run either with an automatically generated configuration
-file or with a custom configuration that requires manual edition.
-
 ### Automated configuration
 
 It is recommended that you use Docker Compose to run your containers, including

 docker-compose up -d
 ```
 
-### Without Compose
-
-If you do not wish to use Compose, you may still run this image using plain
-Docker commands. Note that the following is just a guideline and you may need
-to add parameters to the docker run command to account for the network situation
-with your postgres database.
-
-```
-docker run \
-    -d \
-    --name synapse \
-    -v ${DATA_PATH}:/data \
-    -e SYNAPSE_SERVER_NAME=my.matrix.host \
-    -e SYNAPSE_REPORT_STATS=yes \
-    docker.io/matrixdotorg/synapse:latest
-```
-
-## Volumes
-
-The image expects a single volume, located at ``/data``, that will hold:
-
-* temporary files during uploads;
-* uploaded media and thumbnails;
-* the SQLite database if you do not configure postgres;
-* the appservices configuration.
-
-You are free to use separate volumes depending on storage endpoints at your
-disposal. For instance, ``/data/media`` coud be stored on a large but low
-performance hdd storage while other files could be stored on high performance
-endpoints.
-
-In order to setup an application service, simply create an ``appservices``
-directory in the data volume and write the application service Yaml
-configuration file there. Multiple application services are supported.
-
-## Environment
-
-Unless you specify a custom path for the configuration file, a very generic
-file will be generated, based on the following environment settings.
-These are a good starting point for setting up your own deployment.
-
-Global settings:
-
-* ``UID``, the user id Synapse will run as [default 991]
-* ``GID``, the group id Synapse will run as [default 991]
-* ``SYNAPSE_CONFIG_PATH``, path to a custom config file
-
-If ``SYNAPSE_CONFIG_PATH`` is set, you should generate a configuration file
-then customize it manually. No other environment variable is required.
-
-Otherwise, a dynamic configuration file will be used. The following environment
-variables are available for configuration:
-
-* ``SYNAPSE_SERVER_NAME`` (mandatory), the current server public hostname.
-* ``SYNAPSE_REPORT_STATS``, (mandatory, ``yes`` or ``no``), enable anonymous
-  statistics reporting back to the Matrix project which helps us to get funding.
-* ``SYNAPSE_NO_TLS``, set this variable to disable TLS in Synapse (use this if
-  you run your own TLS-capable reverse proxy).
-* ``SYNAPSE_ENABLE_REGISTRATION``, set this variable to enable registration on
-  the Synapse instance.
-* ``SYNAPSE_ALLOW_GUEST``, set this variable to allow guest joining this server.
-* ``SYNAPSE_EVENT_CACHE_SIZE``, the event cache size [default `10K`].
-* ``SYNAPSE_CACHE_FACTOR``, the cache factor [default `0.5`].
-* ``SYNAPSE_RECAPTCHA_PUBLIC_KEY``, set this variable to the recaptcha public
-  key in order to enable recaptcha upon registration.
-* ``SYNAPSE_RECAPTCHA_PRIVATE_KEY``, set this variable to the recaptcha private
-  key in order to enable recaptcha upon registration.
-* ``SYNAPSE_TURN_URIS``, set this variable to the coma-separated list of TURN
-  uris to enable TURN for this homeserver.
-* ``SYNAPSE_TURN_SECRET``, set this to the TURN shared secret if required.
-
-Shared secrets, that will be initialized to random values if not set:
-
-* ``SYNAPSE_REGISTRATION_SHARED_SECRET``, secret for registrering users if
-  registration is disable.
-* ``SYNAPSE_MACAROON_SECRET_KEY`` secret for signing access tokens
-  to the server.
-
-Database specific values (will use SQLite if not set):
-
-* `POSTGRES_DB` - The database name for the synapse postgres database. [default: `synapse`]
-* `POSTGRES_HOST` - The host of the postgres database if you wish to use postgresql instead of sqlite3. [default: `db` which is useful when using a container on the same docker network in a compose file where the postgres service is called `db`]
-* `POSTGRES_PASSWORD` - The password for the synapse postgres database. **If this is set then postgres will be used instead of sqlite3.** [default: none] **NOTE**: You are highly encouraged to use postgresql! Please use the compose file to make it easier to deploy.
-* `POSTGRES_USER` - The user for the synapse postgres database. [default: `matrix`]
-
-Mail server specific values (will not send emails if not set):
+### More information
 
-* ``SYNAPSE_SMTP_HOST``, hostname to the mail server.
-* ``SYNAPSE_SMTP_PORT``, TCP port for accessing the mail server [default ``25``].
-* ``SYNAPSE_SMTP_USER``, username for authenticating against the mail server if any.
-* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.
+For more information on required environment variables and mounts, see the main docker documentation at [/docker/README.md](../../docker/README.md)

+# Synapse Docker
+
+This Docker image will run Synapse as a single process. It does not provide a database
+server or a TURN server, you should run these separately.
+
+## Run
+
+We do not currently offer a `latest` image, as this has somewhat undefined semantics.
+We instead release only tagged versions so upgrading between releases is entirely
+within your control.
+
+### Using docker-compose (easier)
+
+This image is designed to run either with an automatically generated configuration
+file or with a custom configuration that requires manual editing.
+
+An easy way to make use of this image is via docker-compose. See the
+[contrib/docker](../contrib/docker)
+section of the synapse project for examples.
+
+### Without Compose (harder)
+
+If you do not wish to use Compose, you may still run this image using plain
+Docker commands. Note that the following is just a guideline and you may need
+to add parameters to the docker run command to account for the network situation
+with your postgres database.

+    -e SYNAPSE_SERVER_NAME=my.matrix.host \

+* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.
+
+## Build
+
+Build the docker image with the `docker build` command from the root of the synapse repository.
+
+```
+docker build -t docker.io/matrixdotorg/synapse . -f docker/Dockerfile
+```
+
+The `-t` option sets the image tag. Official images are tagged `matrixdotorg/synapse:<version>` where `<version>` is the same as the release tag in the synapse git repository.
+
+You may have a local Python wheel cache available, in which case copy the relevant
+packages in the ``cache/`` directory at the root of the project.
