This is great news. Congratulations Matthias!

Do we intend to send messages to email and/or Matrix? If so, perhaps we
use a separate Laniakea channel for Matrix so as not to flood the
PureOS channel. I suppose we can use the pureos-changes mailing list
for messages too? pureos-project seems like it might be better left to
higher level topics.

When you say integration testing, what do you mean? Do you mean how the
various components of Laniakea fit together?

I think a description of the test framework you use (TAP? PyTest), and
then a TEMPLATE python script might be a great way to get folks to
contribute. I know I would.

What is the framework for the web app? Is it Angular, Vue, or perhaps
something from Python like flask?

I think a lot of derivative would use this if you could just apt-get
install laniakea. It ought to make their lives much, much easier. I
know this would have helped Maemo when Nokia essentially abandoned it.

URL? Are you using Readthedocs?

I filed a bug. You fixed it too quickly. :P
