Link to proguard rules file is broken in the documentation page.
The following note:

Note: If you use the datastore-preferences-core artifact with Proguard, you must manually add Proguard rules to your proguard-rules.pro file to keep your fields from being deleted. You can find the necessary rules here.

Contains a link on the last word "here" but the link goes to a missing file "The file does not exist at this commit".
