Do I need to install AndroidWorld?

[BlitherBoom812]

I noticed that I need to launch an Android emulator following AndroidWorld, may I ask that, do I need to install AndroidWorld? Or, simply following the first two steps is ok in the reademe?

For running the minimal example, the first two steps in readme are enough. For running the AndroidWorld Benchmark, installing AndroidWorld is necessary.
