+### {% linkable_title UPnP %}
+
 Home Assistant must be on the same network as the devices for uPnP discovery to work.
 If running Home Assistant in a [Docker container](/docs/installation/docker/) use switch `--net=host` to put it on the host's network.

+### {% linkable_title could not install dependency netdisco %}
+
 If you see `Not initializing discovery because could not install dependency netdisco==0.6.1` in the logs, you will need to install the `python3-dev` or `python3-devel` package on your system manually (eg. `sudo apt-get install python3-dev` or `sudo dnf -y install python3-devel`). On the next restart of Home Assistant, the discovery should work. If you still get an error, check if you have a compiler (`gcc`) available on your system.
 
+### {% linkable_title DSM and Synology %}
+
 For DSM/Synology, install via debian-chroot [see this forum post](https://community.home-assistant.io/t/error-starting-home-assistant-on-synology-for-first-time/917/15).
