+        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.
