+GN build system is required for all platforms:\
 https://gn.googlesource.com/gn/
 
 ## Building from the command-line:
 
 ### All platforms except Android:
-Setup:
+#### Setup:
+Generate build files for Ninja in release and debug modes.
 ```text
 gn gen out/release
-gn gen --args="is_debug=true" out/debug
+gn gen --args='is_debug=true' out/debug
 ```
-Building and running:
+#### Building and running:
+Build all games in release mode and run "hello_world".
 ```text
-ninja -C out/debug
+ninja -C out/release
-./out/debug/hello_world
+./out/release/hello_world
+```
+Build "demo" in debug mode and run.
+```text
+ninja -C out/debug demo
 ./out/debug/demo
 ```
+
 ### Android:
+Build "hello_world" in debug mode for all ABIs and install. GN will be run by
+Gradle so no setup is required. Location of gn and ninja executables can be
+specified via "gn" and "ninja" properties (-Pgn="path/gn").
 ```text
 cd build/android
-./gradlew :app:installDebug
+./gradlew :app:installHelloWorldAllArchsDebug
 ```
+Build "demo" in debug mode for x86_64 ABI and install. Valid ABI targets are
+Arm7, Arm8, X86, X86_64, AllArchs, ArmOnly, X86Only.
+```text
+./gradlew :app:installDemoX86_64Debug
+```
+
 ### Generate Visual Studio solution:
 ```text
 gn.exe gen --args="is_debug=true" --ide=vs2022 out\vs
 devenv out\vs\all.sln
 ```
