+### Why does git-cola hang when run via `yadm enter`?
+
+`git-cola` tries to display all of the untracked files in a repository. For
+dotfiles, this is usually a massive list of files. The solution is to configure
+your repo to have `git-cola` ignore untracked files with the following
+configuration.
+
+```
+yadm gitconfig gui.displayuntracked false
+```
