# Prometheus Guide
Important Notice:
-----------------
To ensure I don't make any breaking changes, I have tagged the source code as a snapshot of the time the video was released.
The tag will point to the exact source code I tested when I made the video.
If you are using master branch, there might be breaking changes however I do my best to avoid it.
