Now it's time to create the modpack.
Creating a Modpack
Click File -> New Solution.
Enter the requested information. The name what you want the modpack to be called. This must be something that can be in a filename, as no error checking is currently done (pending #31). Under "type", choose "DS Modpack". Under "Location", choose or create any directory with a decent amount of free space. The modpack and all child mods will be created inside a subfolder of this directory, which is referred to as the solution directory. When you're done, click OK.
Go through the wizard that appears. The first step is just an introduction. Read it, then click "Next >". The second step asks for a ROM. You can give it any decrypted 3DS or NDS ROM. For the purpose of this tutorial, I'll be using Pokémon Mystery Dungeon: Explorers of Sky. After you browse to a supported ROM, click the Extract button, and wait for the extraction to complete. When it's done, click the Finish button.
Click File -> Save -> Save Solution. You can get away without doing it, but if there's a problem further on, this will keep you from needing to repeat these steps. I recommend doing this before and after every time you create, edit, or delete projects. Refer to "Opening a Modpack" below for instructions on how to reopen this solution.
In the Solution Explorer, expand Directory.
Right-click Directory. (If you don't see any context menu items, try left-clicking it, then right-clicking it.) Then click Create Project.
You should be presented with this window:
Like when creating a solution, make sure the Name you choose doesn't contain any invalid path characters.

Opening a Modpack
If you close Sky Editor after saving the solution, here's how to reopen it.
Click File -> Open -> Open (Auto-Detect File Type).
Browse to the directory you chose in step 2 of the previous section. Then open the directory matching the name you chose. Choose the file ending in "*.skysln". If you do not see a file with that extension, and you are 100% sure you are looking in the right location, you did not save your modpack and will need to recreate it.
Your solution is now open, and you can continue at step 5 in the previous section.
