Gyro is provided as four .qc files and must be installed into an existing mod or source base. Once you are ready to proceed, you should follow the steps below:

Step 1
Copy the four .qc files (gyro_forces.qc, gyro_main.qc, gyro_physics.qc and gyro_user.qc) into the source folder of your mod.

Step 2
You now need to add these files to your progs.src file, just under defs.qc, as shown below:

defs.qc
gyro_main.qc
gyro_physics.qc
gyro_forces.qc
gyro_user.qc
subs.qc
fight.qc
...

Step 3
Load defs.qc and find, near the bottom, the remove() function. You will need to alter this into a forward declaration by removing the "= #15" part, leaving the line as:

void(entity e) remove;

Step 4
In order for Gyro to run, we must add a single line to world.qc, in the StartFrame() function. It can be found near the bottom of the file and needs to look something like this:

	...
	skill = cvar("skill");
	framecount = framecount + 1;
	Gyro_Run();
};

Step 5
Installation complete! When you are satisfied that Gyro is installed correctly, you may proceed onto the configuration stage.
