After the corners are solved, use the instructions for the 3-color cube to solve the edges. Restore the corners with half-twists and then use the following sequences to complete the solution. You may not always be able to exactly match a setup but you can always find one that will either reduce the number of misplaced facelets (matching 3 of 4 facelets will fix two) or relocate two of them such that a setup can be matched. Some additional tips for solving the Edge Cube are here.
A quick reference guide for all of the solving sequences is here.
