Document Nyx (arm)
We’ve been shipping `arm` in Tails since 2011, and it’s not mentionned anywhere in our doc. That should be fixed.
- It should at least be listed in /doc/about/features.
- We should also investigate which additional features it bring to advanced users (it runs in a terminal) and explain them in the Advanced Topics sections.
