 # Documentation
 
 Please check the [online documentation](http://l-lin.github.io/angular-datatables/)
 
-# FAQ
-## Why version 4.X? Where is version 3.X? And 1.X?
-
-The major version of the project (it's using a [Semantic versioning](http://semver.org/)) will be synchronized with the major version of Angular.
-
-## Why is there less functionality?
-
-Because, I'm still working on it... But, if you want to contribute, feel free to make a pull request!
-
-## Will you still work on version 0.X.Y?
-
-Nope, not anymore!
-
-## Why no BowerJS? GruntJS?
-
-Let's not multiply the tools and do all in NPM! 
-
-## Where are the DTOptionsBuilder, DTColumnBuilder and DTColumnDefBuilder?
+# Versioning
 
-In the first versions of angular-datatables, there is a builder to help with using the directive.
-However, they seem to have brought more confusion instead. So, starting from version 2, you will need to provide the options directly, like in the DataTable's documentation.
+The major version of the project (it's using a [Semantic versioning](http://semver.org/)) is
+synchronized with the major version of Angular.
