+## Use auto bash-completion
+In case of binary install suggested [here](#installsh), `cmdshelf-completion.bash` is copied under `/usr/local/etc/bash-completion.d`. All you have to do is to make bash be aware of that file.
+
+Either put this in your `~/.bashrc`,
+```shell
+source /usr/local/etc/bash_completion.d/cmdshelf-completion.bash
+```
+
+or install `bash-completion` via homebrew. (Personally I've never managed it to work correctly.)
+
+If you build from source either via `Mint` or manually, then you first have to copy or symlink it manually.
+```shell
+# copy
+cp Sources/Scripts/cmdshelf-completion.bash /usr/local/etc/bash-completion.d/
+
+# or simlink
+ln -s Sources/Scripts/cmdshelf-completion.bash /usr/local/etc/bash-completion.d/cmdshelf-completion.bash
