+## Marlin 2.0 Bugfix Branch
+
+__Not for production use. Use with caution!__
 
 Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
 
+This branch is for patches to the latest 2.0.x release version. Periodically this branch will form the basis for the next minor 2.0.x release.

We've posted detailed instructions on [Building Marlin with Arduino](https://marlinfw.org/docs/basics/install_arduino.html) and [Building Marlin with PlatformIO for ReArm](https://marlinfw.org/docs/basics/install_rearm.html) (which applies well to other 32-bit boards).

+
+Marlin 2.0 introduces a layer of abstraction so that all the existing high-level code can be built for 32-bit platforms while still retaining full 8-bit AVR compatibility. Retaining AVR compatibility and a single code-base is important to us, because we want to make sure that features and patches get as much testing and attention as possible, and that all platforms always benefit from the latest improvements.

+- This branch is for fixing bugs and integrating any new features for the duration of the Marlin 2.0.x life-cycle.
+- Follow the [Coding Standards](https://marlinfw.org/docs/development/coding_standards.html) to gain points with the maintainers.
+- Please submit Feature Requests and Bug Reports to the [Issue Queue](https://github.com/MarlinFirmware/Marlin/issues/new/choose). Support resources are also listed there.
+- Whenever you add new features, be sure to add tests to `buildroot/tests` and then run your tests locally, if possible.
+  - It's optional: Running all the tests on Windows might take a long time, and they will run anyway on GitHub.
+  - If you're running the tests on Linux (or on WSL with the code on a Linux volume) the speed is much faster.
+  - You can use `make tests-all-local` or `make tests-single-local TEST_TARGET=...`.
+  - If you prefer Docker you can use `make tests-all-local-docker` or `make tests-all-local-docker TEST_TARGET=...`.
