\x1b[97mProject folder '${projectName}' created!\x1b[0m

In this new folder, create new .js files with your code in them and run them
using this command with your .js file name from the project folder:

\x1b[90m>\x1b[0m \x1b[92mnode my_script.js\x1b[0m

See the two example scripts in the folder to get started.
\x1b[90m- The reloader example requires fxr-ws-reloader.dll to be installed
  in Elden Ring: https://github.com/EvenTorset/fxr-ws-reloader\x1b[0m

If a new update to the FXR or reloader libraries comes out and you want to
update, double click on the update.bat file in the project folder.
