+kubectx provides shell completion scripts to complete context names, making it
+even faster to switch between contexts easily.
+
+## Bash setup
+
+Copy the `kubectx.bash` file to your HOME directory:
+
+    cp kubectx.bash ~/.kubectx.bash
+
+And source it in your `~/.bashrc` file by adding the line:
+
+    [ -f ~/.kubectx.bash ] && source ~/.kubectx.bash
+
+Start a new shell, type `kubectx`, then hit <kbd>Tab</kbd> to see the existing
+contexts.
+
+You can Add `TAB: menu-complete` to your `~/.inputrc` to cycle through the
+options with <kbd>Tab</kbd>.
