How to use Git for Unity3D source control?

Question

What are best practices for using Git source control with Unity 3D, particularly in dealing with the binary nature of Unity 3D projects? Please describe the workflow, what paths would be included in .gitignore, what settings should be set in Unity and/or the project, and any other special things that should be noted.

Note: I realize that using the Asset Server is the Unity-recommended way, but I would like to use Git for a variety of reasons. Please no answers that state or argue that I should just use the Asset Server. The Asset Server really isn't an option for me.

Unity also Provide its own Source version control. before unity5 it was unityAsset Server but now its depreciated. and launch a new SVN control system called unity collaborate.but the main problem using unity and any SVN is committing and merging scene . but Non of svn give us way to solve this kind of conflicts or merge scene . so depend upon you which SVN you are familiar with . I am using SmartSVN tool on Mac . and turtle on windows .
