Thanks for installing Buck!
In this quickstart project, the file apps/myapp/BUCK defines the build rules.
At this point, you should move into the project directory and try running:
buck build //apps/myapp:app
or:
buck build app
See .buckconfig for a full list of aliases.
If you have an Android device connected to your computer, you can also try:
buck install app
This information is located in the file README.md if you need to access it later.
