Here's a sample of a Photoshop tutorial I would make. Since some of my technical writing experience is from writing bugs while under an NDA, I don't have a record of any of those bugs.
Photoshop tutorial
How to record an action.
1. Create a new document by selecting New from the File drop down menu or inputting Ctrl+N.
2. Input Alt+F9, Window>Actions, or nothing if the Actions Window is already open.
3. Click on the Create new action button at the bottom of the Action Window.
4. Click the Record button.
5. Do the things that you want to record in the specific order that needs to be done.
6. Click the Stop recording/playing button to save the action. 
Your action is now completed. The action can be edited after it is completed.
EQ2 performance settings tutorial
I wrote this for other players in the Everquest 2 raiding guild I was in. The other players were complaining about not being able to see anything on screen while under the effects of the infravision vision effect. I wrote a tutorial explaining how to setup Everquest 2's performance options so that the players can see better while using the minimum amount of hardware resources.
