This repo is used as a way to publish static wasp resources, primarily installer script.
Anything that you put here in master branch will be available under get.wasp-lang.dev/ (via Github Pages).
Therefore, installer.sh will be available as get.wasp-lang.dev/installer.sh .
Test with dash installer.sh, to ensure it works on variety with sh, not just bash (dash is implementation of sh, so simpler than bash, and is a default shell on ubuntu).
Also, use shellcheck to check the code: shellcheck installer.sh.
