Consider adding a .gitattributes file

Hey there! You may want to consider adding a .gitattributes file so that users download just your asset instead of the whole repo. It can be as simple as:
```
# Normalize line endings for all files that Git considers text files.
* text=auto eol=lf

# Only include the addons folder when downloading from the Asset Library.
/** export-ignore
/addons !export-ignore
/addons/** !export-ignore
```
