 # What to do if Dorothy is not loading
 
-Installed Dorothy, opened a new terminal, but none of the Dorothy commands are available?
+You've installed Dorothy, opened a new terminal, but none of the Dorothy commands are available?
 
 It could be that your terminal application is refusing to operate your shell as a login shell, which is how Dorothy (and many other applications) identify whether they should complete loading themselves. If Dorothy were to load itself on non-login shells then every shell command would also have to load Dorothy which would be be an unnecessary slow down to every shell command! By having Dorothy only load inside login shells, we allow everything to work perfectly.
 
 So what to do when your terminal isn't opening a login shell?
 
-## Ubuntu
+## Manual Invocation
 
-In the top menu bar, tap the terminal application title, and open preferences:
+You can manually invoke a login shell by executing any of these commands:
+
+- Bash: `bash -l`
+- ZSH: `zsh -l`
+- Fish: `fish -l`
+- Nu: `nu -l`
+- Xonsh: `xonsh -l`
+- Elvish: elvish doesn't have the concept of login shells, so this does not apply.
+- Dash: `dash -l`
+- KSH: `ksh -l`
+
+## Gnome Terminal (Ubuntu, Debian, etc.)

+Open the `Terminal` application. In the top menu bar, tap the `Terminal` application title, then open `Preferences`:
