Hey there!
|
||
|
||
If you're thinking of working on Lix, please consider talking to us about it!
|
||
You should be aware that we are ${sgr}1mnot${sgr}0m accepting major features without some conditions,
|
||
and we highly recommend looking at our freeze status page on the wiki:
|
||
${sgr}32m${freezePage}${sgr}0m
|
||
|
||
We also have an overview of the codebase at
|
||
${sgr}32m${codebaseOverview}${sgr}0m,
|
||
and other helpful information on the wiki.
|
||
|
||
But above all else, ${sgr}1mwe want to hear from you!${sgr}0m
|
||
We can help you figure out where in the codebase to look for whatever you want to do,
|
||
and we'd like to work together with all contributors as much as possible.
|
||
Lix is a collaborative project :)
|
||
|
||
You can open an issue at https://git.lix.systems/lix-project/lix/issues
|
||
or chat with us on Matrix: #space:lix.systems.
