The guide covers aspects such as:

• What counter cancels are

• How to perform them

• How to do fast movement

• How to fight

• Kill strats for each enemy in the game

And more.

Some things go outside the scope of both speedrunning and Ruby herself, but overall there is a plethora of information to get started with running the game.

Speedrunning segment can be found at the end of the video for more specifics regarding the topic.

Consider it a kind of all-in-one game guide with a focus on playing Ruby. Other characters will play/perform differently, but a lot of skills learned here can be transferred over to other characters.
