 # Contributing to GitVersion

 We love contributions to get started contributing you might need:
 
- - [Get started with git](http://rogerdudler.github.io/git-guide)
- - [How to create a pull request](https://help.github.com/articles/using-pull-requests)
- - [An issue to work on](https://github.com/GitTools/GitVersion/labels/up-for-grabs) - We are on [Up for grabs](http://up-for-grabs.net/), our up for grabs issues are tagged `up-for-grabs`
- - An understanding of our [architecture](http://gitversion.readthedocs.org/en/latest/more-info/how-it-works/#architecture) and how [we write tests](#writing-tests)

 Once you know how to create a pull request and have an issue to work on, just post a comment saying you will work on it.
 If you end up not being able to complete the task, please post another comment so others can pick it up.
 
 Issues are also welcome, [failing tests](#writing-tests) are even more welcome.

+- The documentation is stored in the repository under the [`docs`](docs) folder.
    Have a look at the [documentation readme file](docs/readme.md) for guidance
    on how to improve the documentation and please include documentation updates

-# Writing Tests
+## Writing Tests
+
 We have made it super easy to write tests in GitVersion. Most tests you are interested in are in `GitVersionCore.Tests\IntegrationTests`.
 
 There is a scenario class for each type of branch. For example MasterScenarios, FeatureBranchScenarios etc.
 
-## 1. Find Appropriate Scenario class

 Find where your issue would logically sit. Or create a new scenario class if it doesn't fit anywhere in particular.

 We are currently using NUnit, so just create a descriptive test method and attribute it with `[Test]`
 
-## 3. Use a fixture
+### 3. Use a fixture

 We have a few fixtures for different scenarios.
 
- - `EmptyRepositoryFixture` - Gives you an empty git repo to start with
- - `RemoteRepositoryFixture` - A local repo tracking a test remote repository. The remote repo is available through the `Repository` property, the local is accessible via `LocalRepository`
- - `BaseGitFlowRepositoryFixture` - A repo setup for GitFlow (has a develop branch checked out ready to go)

 You can use a fixture by just `using` it. Like this

 ``` csharp
 using (var fixture = new EmptyRepositoryFixture(new Config()))
 {
 }
 ```

 We have a number of extension method off `IRepository` to make it easy to write tests at the flow level and not worry about creating/commiting files.
 
 An example test looks like this:

 ``` csharp
 fixture.Repository.MakeATaggedCommit("1.0.0");
 fixture.Repository.CreateBranch("feature-test");

 The last line is the most important. `AssertFullSemver` will run GitVersion and assert that the full SemVer it calculates is what you expect.

 ## Docker

 It is a manual release step after the release now, first download the appropriate ZIP and put into a `releaseArtifacts` folder in the GitVersion repository, then run:
 
-`docker build . --build-arg GitVersionZip=GitVersion_<VERSION>.zip --tag gittools/gitversion`
+```bash
+docker build . --build-arg GitVersionZip=GitVersion_<VERSION>.zip --tag gittools/gitversion
