 Troubleshooting
 ---------------
-
-Most likely your terminal is `xterm` and does not support dynamic titles.
-
 After a correct installation the title of a tmux session should end with "- TMUX" and "- VIM" or "- NVIM" for vim or nvim sessions respectively.
 You can check the title (property `WM_NAME`) by using `xprop`.
+
+In case your title does not change, your terminal and/or shell do not support dynamic titles.
+
+- `xterm` does not support dynamic titles. Time to move on, boomer.
+- Your shell is not configured. Try the provided minimal configurations for `zsh` or `bash`: 
+
+```
+echo "source ~/.config/awesome/awesomewm-vim-tmux-navigator/dynamictitles.zsh" >> ~/.zshrc
+```
+
+or
