+# Contributing to Bazel
 
-### Before you contribute
-**Before we can use your code, you must sign the
-[Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual?csw=1)
-(CLA)**, which you can do online.
+## Contributor License Agreement
 
-The CLA is necessary mainly because you own the copyright to your changes,
-even after your contribution becomes part of our codebase, so we need your
-permission to use and distribute your code. We also need to be sure of
-various other things — for instance that you'll tell us if you know that
-your code infringes on other people's patents. You don't have to sign
-the CLA until after you've submitted your code for review and a member has
-approved it, but you must do it before we can put your code into our codebase.
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution,
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to <https://cla.developers.google.com/> to see
+your current agreements on file or to sign a new one.
 
-Before you start working on a larger contribution, you should get in touch
-with us first. Use the issue tracker to explain your idea so we can help and
-possibly guide you.
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
 
-### Code reviews and other contributions.
-**All submissions, including submissions by project members, require review.**
-Please follow the instructions in [the contributors documentation](http://bazel.build/contributing.html).
+## Patch Acceptance Process
 
-### The small print
-Contributions made by corporations are covered by a different agreement than
-the one above, the
-[Software Grant and Corporate Contributor License Agreement](https://cla.developers.google.com/about/google-corporate).

 *{Fast, Correct} - Choose two*
 
-Bazel is a build tool that builds code quickly and reliably. It is used to build
-the majority of Google's software, and thus it has been designed to handle
-build problems present in Google's development environment, including:
+Build and test software of any size, quickly and reliably.
 
-* **A massive, shared code repository, in which all software is built from
-source.** Bazel has been built for speed, using both caching and parallelism
-to achieve this. Bazel is critical to Google's ability to continue
-to scale its software development practices as the company grows.
+* **Speed up your builds and tests**:
+  Bazel only rebuilds what is necessary.
+  With advanced local and distributed caching, optimized dependency analysis and
+  parallel execution, you get fast and incremental builds.
 
-* **An emphasis on automated testing and releases.** Bazel has
-been built for correctness and reproducibility, meaning that a build performed
-on a continuous build machine or in a release pipeline will generate
-bitwise-identical outputs to those generated on a developer's machine.
+* **One tool, multiple languages**: Build and test Java, C++, Android, iOS, Go
+  and a wide variety of other language platforms. Bazel runs on Windows, macOS,
+  and Linux.
 
-* **Language and platform diversity.** Bazel's architecture is general enough to
-support many different programming languages within Google, and can be
-used to build both client and server software targeting multiple
-architectures from the same underlying codebase.
+* **Scalable**: Bazel helps you scale your organization, codebase and Continuous
+  Integration system.
+  It handles codebases of any size, in multiple repositories or a huge monorepo.
 
-Find more background about Bazel in our [FAQ](http://bazel.build/faq.html).
+* **Extensible to your needs**: Easily add support for new languages and
+  platforms with Bazel's familiar extension language. Share and re-use language
+  rules written by the growing Bazel community.
