BREAK OUT THE RCS AND SAS, HERE'S AN UNTESTED TUTORIAL ON KSP DOCKING

1) Build a craft with SAS, some monopropellant (usually 200+ is plenty for small craft), and those 4 way thruster things. Put a set of 4 on both the front AND back of the docking stage of your ship. Instead of a docking port, use the grabber thing. The grabbing unit can grab anything and you don't need to worry about being correctly oriented, so it's perfect for learning how to dock.

2) Get to orbit.

3) Get a second craft to orbit and use your Mun landing skills to get close (~1km away or thereabouts) to the first craft. Make sure you set the first craft as the target.

4) Click your speed indicator to switch it from Orbit or Surface to Target. This now shows your relative speed to the target.

5) Kill your target speed to 0 (or as close as you can to it) by burning retrograde

6) Switch to LOCKED camera move by pressing V until it says LOCKED. This makes it a ton easier to understand where the heck you're going. Move the camera to the back of the ship so you're looking down its thruster.

7) Turn on RCS and SAS if you haven't already, and practice moving around! Use IJKL with your right hand, and WASD with your left hand.

Tap each of the keys to see what each motion does. Your left hand ORIENTS you (ie: makes you POINT in a certain direction). Your right hand TRANSLATES you (ie: strafes you up/down/left/right).

There are two more important keys: H and N.

H moves you forward.

N moves you backward.

Try moving forward slowly to start, and note what WASD, IJKL, and HN each do to your prograde marker.

Now come to a complete stop (0 m/s relative to target).

8) Open the grabber unit. Also right click on it and select "Control from here." This makes your navball lock to the grabber unit.

9) Try moving to the target at 5 m/s. That's to the Target Prograde icon. Use WASD to orient yourself and H to move forward.

10) Once you get to ~100m from your target (you can timewarp a little here), slow down to 3 m/s. Make course corrections as needed but do not go faster than 3 m/s. It's tough at first, but it only gets easier with practice!

Now is a good time to quicksave.

11) When you are ~30m from your target, slow down to 1m/s. Try to stay as straight as you can, using IJKL and WASD as needed.

If you panic, just point yourself prograde (green forward) and use N to come to a complete stop! Then reorient yourself target prograde and continue slowly.

12) With some luck and a lot of newly learned skill, you'll eventually hook onto the first craft! You can even transfer fuel and such. Cool!

13) Once you get the hang of the grabber, the next step is using docking ports, which just adds orientation. You just need to make sure both craft have their ports pointed at one another. Remember you can switch between nearby vessels using the [ and ] keys.

Let me know if you have any questions!

Ok I have to get back to work now.
