how-to-use.md

1. Create a folder in Google Drive

2. Create a new Apps Script in the folder

3. Copy Code.gs and index.html into the script

4. Replace FOLDER ID HERE in Code.gs with the ID of the folder containing the script.

5. Replace Wurst-Imperium/Wurst-Client in index.html with the name of your repo.

6. Run createFile() once.

7. Add a trigger for update() that fires once per minute.

8. Place this code where you want the badge to appear:

[![downloads](https://drive.google.com/uc?id=FOLDER_ID_HERE)](https://github.com/REPO_NAME_HERE/releases/latest)

(Make sure to replace FOLDER_ID_HERE and REPO_NAME_HERE with the folder ID and repo name.)
