Hello.
Description
===========
In `/usr/local/share/doc/pkg-readmes/synapse` ,
I found wrong command in "Generate a config" section.
How to reproduce
================
1. Install synapse via `pkg_add synapse`
2. Run the command lines in the section. `--generate-keys` can't be used with
`--generate-config`.
How to fix
==========
1. The command lines should be:
```diff
doas -u _synapse /usr/local/bin/python3.9 -m synapse.app.homeserver \
-c /var/synapse/homeserver.yaml --generate-config \
--server-name matrix.example.com --report-stats=no \
- --generate-keys --keys-directory /var/synapse
+ --keys-directory /var/synapse
````
Thank you for your reading and always for great projects.
