### Generating a config file
It is possible to generate a basic configuration file for use with
`SYNAPSE_CONFIG_PATH` using the `generate` commandline option. You will need to
specify values for `SYNAPSE_CONFIG_PATH`, `SYNAPSE_SERVER_NAME` and
`SYNAPSE_REPORT_STATS`, and mount a docker volume to store the data on. For
example:
```
docker run -it --rm
--mount type=volume,src=synapse-data,dst=/data \
-e SYNAPSE_CONFIG_PATH=/data/homeserver.yaml \
-e SYNAPSE_SERVER_NAME=my.matrix.host \
-e SYNAPSE_REPORT_STATS=yes \
matrixdotorg/synapse:latest generate
```
This will generate a `homeserver.yaml` in (typically)
`/var/lib/docker/volumes/synapse-data/_data`, which you can then customise and
use with:
```
docker run -d --name synapse \
--mount type=volume,src=synapse-data,dst=/data \
-e SYNAPSE_CONFIG_PATH=/data/homeserver.yaml \
matrixdotorg/synapse:latest
```
