Guava has mostly not used the CONTRIBUTORS file, instead relying on Git
history. You can see a summary of contributions at
https://github.com/google/guava/graphs/contributors. However, Git history
over-counts some people's contributions because they were responsible for
mirroring out changes from our internal repo.

This files serves mainly to credit people who have not received proper credit
in the Git history.

don't have to do anything. The specific rules are [already bundled][okhttp3_pro] into the JAR which can be
interpreted by R8 automatically.

If you, however, don't use R8 you have to apply the rules from [this file][okhttp3_pro]. You might
also need rules from [Okio][okio] which is a dependency of this library.
