 ### Build Stride
 
-1. Clone Stride: `git clone https://github.com/stride3d/stride.git`
-2. Open `<StrideDir>\build\Stride.sln` with Visual Studio 2019, and build.
-3. Open `<StrideDir>\samples\StrideSamples.sln` and play with the samples.
-4. Optionally, open and build `Stride.Android.sln`, `Stride.iOS.sln`, etc...
+1. Open a command prompt, point it to a directory and clone Stride to it: `git clone https://github.com/stride3d/stride.git`
+2. Open `<StrideDir>\build\Stride.sln` with Visual Studio 2019 and build `Stride.GameStudio` (it should be the default startup project) or run it from VS's toolbar.
+* Optionally, open and build `Stride.Android.sln`, `Stride.iOS.sln`, etc.
+
+If building failed:
+* If you skipped one of the `Prerequisites` thinking that you already have the latest version, update to the latest anyway just to be sure.
+* Visual Studio might have issues properly building if an outdated version of 2017 is present alongside 2019. If you want to keep VS 2017 make sure that it is up to date and that you are building Stride through VS 2019.
+* Some changes might require a system reboot, try that if you haven't yet.
+
+Do note that test solutions might fail but it should not prevent you from building `Stride.GameStudio`.
