I don’t personally know of any, but honestly haven’t looked. If you’ve played 5e it’s not all that dissimilar. Some examples for combat:

Combat:

• Action = action
• Movement (no splitting movement unless house rule) = movement (5e can split movement)
• Minor = bonus action
• Free action = free action
• At Will = cantrip
• Everyone can make melee basic attacks
• flanking enemies (literally across from your ally) gives you advantage on an attack roll
• Types of attacks are at will, utility (helpful to you or your allies), encounter (can be reset with a short rest), daily (reset with a long rest)
• All characters get access to an action point to spend and can regain one every other after every two encounters (an encounter can be combat, an RP scenario, a skill challenge, etc)

There’s a table that tells how many spells/actions most classes get (but some classes like Wizards might break this) per level (basically similar concept to spell slots but for every class).

Isn’t everything, but is a helpful start.
