First, I thank you very much for the awesome matomo tracking software! I'm using it for many years now. Sadly I'm now very disappointed of the current version of this php tracking library :(
I can't find any example, or any installation instructions.
I used your php library for many years now and suddenly it was broken!
Today I tried to update and I was very happy to see you published your library as composer installable.

Please give me a code sample with a basic example that shows how to track with the token auth.

BTW: The reason everything broke is an authentication error.
