 ## Building
 
-We're using [Cake](https://github.com/cake-build/cake) as a 
-[dotnet tool](https://docs.microsoft.com/en-us/dotnet/core/tools/global-tools) 
-for building. So make sure that you've restored Cake by running 
-the following in the repository root:
-
 ```
 > dotnet tool restore
 ```
 
 After that, running the build is as easy as writing:
 
 ```
-> dotnet cake
+> dotnet make
 ```
