One approach I took in a recent project was keeping the documentation in documentation folders under each project, using markdown. It was good because documentation was tied to the source control and easy to locate and read when you were working on the project. It's easy that wiki's become neglected and forgotten if there's not someone that "cracks the whip" so to speak so I think any way to lessen the friction and bring it into the coding environment is a good one
