+# Shaun's `fish` Dotfiles
+
+## Location
+The configuration files need to be present at this location, `~/.config/fish`. So, we can use the following command to softlink/symlink,
+
+```bash
+ln -s <location of cloned dotfiles fish directory> ~/.config/fish
+# e.g.
+# ln -s ~/dotfiles/fish ~/.config/fish
+```
+Ensure the file is adjusted (or a copy is made instead) which uncomments lines for the corresponding linux distro.
