 ## Basic Usage
 In [Visual Studio Online](https://www.visualstudio.com/) build vNext (the web based build system) you can call GitVersion either using the Command Line build step or install a custom build step. This requires a one-time setup to import the GitVersion task into your VSO instance.

+### Using GitVersion with the MSBuild Task NuGet Package
 1. Add the [GitVersionTask](https://www.nuget.org/packages/GitVersionTask/) NuGet Package to your projects.
 
-See [MSBuild Task](http://gitversion.readthedocs.org/en/latest/usage/#msbuild-task) for further instructions how to use the MS Build Task.

+### Using GitVersion with the Command Line build step
 1. Make sure to have GitVersion.exe under version control. There exists also a [Chocolatey package](https://chocolatey.org/packages/GitVersion.Portable) for installing GitVersion.exe on build agents.
 2. Add a Command Line build step to your build definition. You'll probably want to drag the task to be at or near the top to ensure it executes before your other build steps.

 5. If you want the GitVersionTask to update AssemblyInfo files add `updateAssemblyInfo true` to the Arguments parameter.

-### Using the GitVersion VSO Build Step
+#### Using the GitVersion VSO Build Step
 From a VSO vNext build definition, select "Add a Step" and then in the Build category, choose GitVersion and click Add. You'll probably want to drag the task to be at or near the top to ensure it executes before your other build steps.
 
 If you want the GitVersionTask to update AssemblyInfo files, check the box in the task configuration. For advanced usage, you can pass additional options to the GitVersion exe in the Additional arguments section.
 
-## Using the GitVersion Variables
-GitVersion writes build parameters into VSO, so they will automatically be passed to your build scripts to use. It also writes GITVERSION_* environment variables that are available for any subsequent build step.

+### Using the GitVersion Variables
+GitVersion writes build parameters into VSO, so they will automatically be passed to your build scripts to use. It also writes GITVERSION_* environment variables that are available for any subsequent build step. 
+We output the individual values of the GitVersion version as the build parameter: `GitVersion.*` (Eg: `GitVersion.Major`) if you need access to them in your build script.
+See [Variables](/more-info/variables/) for an overview of available variables.
 
 Note that due to [current limitations in VSO](https://github.com/Microsoft/vso-agent-tasks/issues/380) it's currently not possible to set the build version inside of VSO to one of the GITVERSION_* variables.
