1. Move to game directory (i.e. \steamapps\common\insurgency2\insurgency\)
   
2. Move into custom folder, if doesn't exist create one and enter it.
   
3. Inside it create a folder with a name you like (i.e. mypresets)
   
4. Move into it and create folder structure:

Now that you created the folder structure needed for the mod, we can start with the presets :)
If you want to create a preset for 'Insurgents' go into the ins folder, if for 'Security' go into the sec folder.

As example we will create a preset for the 'Rifleman' in 'Security' team.

Create a file called 'rifleman1.cfg' for preset slot one(1), for slot two(2) use 'rifleman2.cfg' or for slot three(3) 'rifleman3.cfg'.

Filename - Reference:


Open the file with a text editor, here we will put some commands which get executed once you press the button ingame.
We will be using following commands to set your preset:

As you can see we need some IDs for the commands, check out discussions with [List] for IDs for certain theaters, I currently provide lists for default theaters:
Normal (firefight, push etc.)
Coop (checkpoint)

Before we start, the file gets read from top to bottom. Which means what you really want must be close to the top, because I don't know how much points you got available to purchase stuff.
Note: 'Slot' can change depending in which order you buy the weapons (i.e. knife=0, primary=1,secondary=2,grenade=3 or secondary=0, grenade=1, knife=2, primary=3 etc. I hope you get what I mean)

Here a template with comments:

In the example above we really want to have the ammo > armor > primary > secondary > and if enough points > grenades.

Once you have your build done save the file and startup the game, if you don't know how to create a autoexec there is a small button in the inventory screen which will setup all the variables needed for this game session.

Sad thing is I didn't find out how to add a second grenade if for example you got the chest carrier selected.
