 You can configure [Travis CI](https://travis-ci.org/) to install the .NET Core SDK using the `csharp` language and the `dotnet` key. For more information, see the official Travis CI docs on [Building a C#, F#, or Visual Basic Project](https://docs.travis-ci.com/user/languages/csharp/). Note as you access the Travis CI information that the community-maintained `language: csharp` language identifier works for all .NET languages, including F#, and Mono.
 
-Travis CI runs both macOS and Linux jobs in a *build matrix*, where you specify a combination of runtime, environment, and exclusions/inclusions to cover your build combinations for your app. For more information, see the [.travis.yml example](https://github.com/dotnet/docs/blob/master/.travis.yml) file and [Customizing the Build](https://docs.travis-ci.com/user/customizing-the-build) in the Travis CI documentation. The MSBuild-based tools include the LTS (1.0.x) and Current (1.1.x) runtimes in the package; so by installing the SDK, you receive everything you need to build.

 # Asynchronous programming
 
 If you have any I/O-bound needs (such as requesting data from a network or accessing a database), you'll want to utilize asynchronous programming.  You could also have CPU-bound code, such as performing an expensive calculation, which is also a good scenario for writing async code.
