New Project Template

This repository contains a template that can be used to seed a repository for a new Google open source project.

See go/releasing (available externally at https://opensource.google/documentation/reference/releasing) for more information about releasing a new Google open source project.

This template uses the Apache license, as is Google's default. See the documentation for instructions on using alternate license.

    • There is no reason to fork it.
  2. Create a new local repository and copy the files from this repo into it.
  3. Modify README.md and docs/contributing.md to represent your project, not the template project.
  4. Develop your new project!
