-The easiest way is to set your target to the object you want to rendezvous with.
-Get your orbits setup for a close approach (anything under 2km)
-Switch your nav ball to display velocity relative to the target.
-Now your pro-grade and retrograde icons on the ball will show relative velocity.
-Burn retro-grade to zero out your velocity relative to the target
-Use the nav-ball to point towards your target.
-Accellerate slowly towards your target(5-10m/s)
-Use time acceleration to inch closer.
-When you start moving away from your target use the nav ball to cancel out your velocity relative to the target.
-Rinse and repeat until you are 100m or so from the target.
-Switch on the RCS and make sure you set it to docking mode.
-You can hit space bar to toggle WASD between the two modes. One mode rotates you, the other mode translates you.
This isn't the most efficient way, but its the least complex once you understand it.
Alternatively you could watch one of the millions of videos on youtube explaining it. I suggest Scott Manley.
