 ### Commands in dotnet.dll
+
 Developers are generally encouraged to avoid adding commands to `dotnet.dll` or the CLI installer directly. This is appropriate for very general commands such as restore, build, publish, test, and clean, but is generally too broad of a distribution mechanism for new commands. Please create an issue and engage the team if you feel there is a missing core command that you would like to add.
 
 ### Tools NuGet packages
+
 Many existing extensions, including those for ASP.NET Web applications, extend the CLI using Tools NuGet packages. For an example of a working packaged command look at `TestAssets/TestPackages/dotnet-hello/v1/`.
 
 ### MSBuild tasks & targets
+
 NuGet allows adding tasks and targets to a project through a NuGet package. This mechanism, in fact, is how all .NET Core projects pull in the .NET SDK. Extending the CLI through this model has several advantages:
 
 1. Targets have access to the MSBuild Project Context, allowing them to reason about the files and properties being used to build a particular project.

 Targets are invoked by calling `dotnet msbuild /t:{TargetName}`
 
 ### Commands on the PATH
+
 The dotnet CLI considers any executable on the path named `dotnet-{commandName}` to be a command it can call out to. 
 
 ## Things to Know
+
 - Any added commands are usually invoked through `dotnet {command}`. As a result of this, stdout and stderr are redirected through the driver (`dotnet`) and buffered by line. As a result of this, child commands should use Console.WriteLine in any cases where they expect output to be written immediately. Any uses of Console.Write should be followed by Console.WriteLine to ensure the output is written.
