 Features:
 ------------
-- Define your own icons
-- Set custom icons for terminal applications
+- Define your own icons for applications
+- Set custom icons for terminal applications by using regular expressions
 
 Prerequisite:
 ------------
 You need to configure your shell and terminal to support dynamic titles.
+Verify your setup by typing `sleep 5` in your terminal. If the title  (`WM_NAME`) of the terminal changes while sleep is running, you are good to go.
+Otherwise your shell is most likely not configured to show dynamic titles.
+
+Minimal configurations are provided for `bash` and `zsh`:
+
+```
+echo "source ~/.config/awesome/icon_customizer/dynamictitles.bash" >> ~/.bashrc
+echo "source ~/.config/awesome/icon_customizer/dynamictitles.zsh" >> ~/.zshrc
