+## Disabling RESH
+
+If you have a persistent issue with RESH you can temporarily disable it and then enable it later.

+```sh
+[[ -f ~/.resh/shellrc ]] && source ~/.resh/shellrc
+[[ -f ~/.bash-preexec.sh ]] && source ~/.bash-preexec.sh # bashrc only
+```

+
+You can re-enable RESH by uncommenting the lines above or by re-installing it.
