Thanks. I don't have the same file structure in the readme so it's going to take some research.
This is a checklist far from the real one, but that will get you flying quick and safely. Use at your discretion.
Extract this inside of "C:\Users\"your name"\Saved Games\DCS".
Check if the file is in the "C:\Users\"your name"\Saved Games\DCS\Kneeboard\"plane type" folder.
You will find the checklist on your DCS Kneeboard. If you have more than one DCS version, repeat the step above to each version.
