Fonts are built automatically by GitHub Actions - take a look in the "Actions" tab for the latest build.
If you want to build fonts manually on your own computer:
make buildwill produce font files.make testwill run FontBakery's quality assurance tests.make proofwill generate HTML proof files.
The proof files and QA tests are also available automatically via GitHub Actions - look at https://yourname.github.io/your-font-repository-name.
For information on how to work on Noto fonts, how the build process works and how to maintain it, see the README file of the notofonts.github.io repository
