 # Contributing to Blockly
 
-Want to contribute? Great!
-
-- First, read this page (including the small print at the end).
-- Second, please make pull requests against develop, not master. If your patch
-  needs to go into master immediately, include a note in your PR.
-
-For more information on style guide and other details, head over to the [Blockly Developers site](https://developers.google.com/blockly/guides/modify/contributing).
-
-### Before you contribute
-
-Before we can use your code, you must sign the
-[Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual)
-(CLA), which you can do online. 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.
-
-### Larger changes
-
-Before you start working on a larger contribution, you should get in touch with
-us first through the issue tracker with your idea so that we can help out and
-possibly guide you. Coordinating up front makes it much easier to avoid
-frustration later on.
-
-### Code reviews
-
-All submissions, including submissions by project members, require review. We
-use Github pull requests for this purpose.
-
-### Browser compatibility
-
-We care strongly about making Blockly work on all browsers. As of 2022 we
-support Edge, Chrome, Safari, and Firefox. We will not accept changes that only
-work on a subset of those browsers. You can check [caniuse.com](https://caniuse.com/)
-for compatibility information.
-
-### 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).
