My DLC test isn't ready for prime time so instead I'm providing my mods in the form of a zip file containing modified ME3 game pcc files. Instructions for installing the mod is included in the file. Basically, you simply replace the original pcc files of the same name with the pcc files supplied in the zip file, run ME3Explorer TOCbinUpdater tool to update your game and prepare it to accept the mods, then start the game and play.
So far I've updated my Ashley, Miranda, and EDI mods in this way. In the near(ish) future I will see about getting the DLC form to work properly. Essentially, the DLCs work for my game but wont work for anyone else due to an inherent texture clash created by my DLC. There is a way to fix this so ALL players can use my mods as DLC but it is fairly time-consuming and complex to set up so it will be some time before I have them ready.
