How to change bash terminal prompt string and color

I am using bash on Windows and the bash prompt string I see is too big: [email protected]:/#, I would rather like it to be a hash (#) or a dollar ($) sigh, let's see how we can change it,

1. Open bash,
2. Type su root to switch to root account,
3. Now type nano ~/.bashrc to open the bashrc file where we will set the PS1 prompt configuration,
4. At the end of the file type PS1="\e[0;32m $ \e[0m",
5. Press Ctrl + O and Enter, and press Ctrl + O to exit,
6. Either close the bash terminal or type source ~/.bashrc to apply changes,
7. You prompt now should be in a $ green color.
