Create A Project
This page will show you how to create a new Intellij project and import your Arma 3 Mission file folder (*.altis, *.VR, etc.)

Click on "Create a New Project"
Click next once you have selected "Empty Project". You can create a project for an Arma mission from selecting "Arma Mission", but this way will make a little more sense. An empty project has no modules inside which is where the Arma mission would reside. If you were to click "Arma Mission" instead of "Empty Project", the project location must be the mission file folder (more on that later) and the module will automatically be created.
This screen will prompt to give the project a name. The name can be anything you'd like. Notice the "Project location" text field. If you chose a non-empty project and instead chose "Arma Mission", this exact dialog would appear and that field is where the Arma mission file folder (i.e. something.altis) should be selected.
You can create a new module by closing the above dialog and going to File -> New -> Module.
A module houses the mission file itself (SQF files, Header files, etc). Create a new module this way.
Select "Arma Mission" and click next.
Time to locate the module source directory. The module name can be anything you'd like.
Click finish.
All of your mission file contents should be loaded. You can see the .iml file created by Intellij that was mentioned earlier.
