 ## Configs
 
-My Linux configs. Included is cmg is a small script to manage symbolic links.
-Each config has a comment including the actual path to the file. For example
-bashrc contains:
-
-    # [cmgr] .bashrc
-
-Several of the functions in my bashrc are sourced from this [thread][1] on the
-Arch Linux forums. In particular:
-
-- [tputcolors is by Gen2ly][2]
-- aur is based on [brisbin33's aurget][3]
-- cpf, mvf, goto by [drcouzelis and brisbin33][4]
-- cfg based on Peasantoid's Python [string manager][5]
-- [define is by gadamat][6]
-- yt is from [this YouTube video][7]

+My Linux configs.
+
+Previously I was storing my configs in `~/configs` and using symlinks to link
+them into place. This worked though the whole symlink thing was a bit of a
+nuisance. It was an extra step that was required. Recently I came across a
+[better way][1] using a bare git repo. Configs are stored in `~/.cfg` as a bare
+git repo and are checked out directly into the home directory. This relies on a
+couple of things.
+
+First clone your configs as a bare repo:
+
+`git clone --bare <git-repo-url> $HOME/.cfg`
+
+Then define an alias:
+
+`config='/usr/bin/git --git-dir=$HOME/.cfg/ --work-tree=$HOME'`
+
+This tells git to use `~/.cfg` as the repo and `~` as the working directory.
+Next tell git to ignore untracked files using the above alias:
+
+`config config --local status.showUntrackedFiles no`
+
+You can then interact with the git repo using `config` and standard git commands
+such as `config ls-files`, `config diff`, `config commit`, etc.
+
+See the link above for a full description of how this works.
