Click there, scroll down to the end of the page and download "OFP Uber Editor Tutorial (10 MB) "
Inside the zip you can find an OFP mission editor manual in PDF format, 300 pages of very interesting and well explained readings that comes with illustrated example on how to use the mission editor and create missions.
You can check the OFPEC tutorials page too, you will find lot of answers to begin with the editor in those.
