You start out just like Mars-Earth, but it changes after you leave Mars' SOI.
Keep in mind that timing the arrival correctly can save almost 2000 m/s on the lunar insertion burn. You want to intercept the Moon's orbital path on the tangent - so pay attention to the Moon will be at TIn. For this flight, you want the Moon to be on the opposite side (of Earth) from the Sun, maybe leading slightly.
Once you leave Mars' SOI, you will need to adjust your course using Target Offsetting or by using Delta V program. Both would be used with IMFD's map set to TGT "Moon", CNT "p-moon", with Int and Plan enabled.
Either method is a bit to complicated for a forum post to cover, but I find Delta-V is easier for me. You need to watch three things - intercept the Moon's orbit at an "edge", time it so the Moon is there when you get there, and ensure the intercept is at a node.
Adjusting any one velocity vector will change all three targets, so there is a lot of back and forth adjusting. Early corrections should be made with mostly dVf to adjust the arrival time, and dVp to adjust the node, then dVi to correct the course to hit the Moon's orbit. Just get in the ballpark at first - and narrow it down during the later corrections. Done properly, Planet Approach won't be needed, Delta-V and Map can put you into the correct insertion orbit for your target base.
Simply using Planet Approach set to Moon instead of Earth MAY work sometimes (but will likely be inefficient), other times it won't work - and sometimes it will take you directly into the Earth! Remember - Planet Approach doesn't consider the gravity or even existence of any bodies other than vessel and target.
