-## Marlin 2.0 Bugfix Branch
-
-__Not for production use. Use with caution!__
+## Marlin 2.0
 
 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.
-
 Download earlier versions of Marlin on the [Releases page](https://github.com/MarlinFirmware/Marlin/releases).
 
 ## Building Marlin 2.0
 
-To build Marlin 2.0 you'll need [Arduino IDE 1.8.8 or newer](https://www.arduino.cc/en/main/software) or [PlatformIO](http://docs.platformio.org/en/latest/ide.html#platformio-ide). We've posted detailed instructions on [Building Marlin with Arduino](http://marlinfw.org/docs/basics/install_arduino.html) and [Building Marlin with PlatformIO for ReArm](http://marlinfw.org/docs/basics/install_rearm.html) (which applies well to other 32-bit boards).
+To build Marlin 2.0 you'll need [Arduino IDE 1.8.8 or newer](https://www.arduino.cc/en/main/software) or [PlatformIO](http://docs.platformio.org/en/latest/ide.html#platformio-ide). Detailed build and install instructions are posted at:
 
-## Hardware Abstraction Layer (HAL)
+  - [Installing Marlin (Arduino)](http://marlinfw.org/docs/basics/install_arduino.html)
+  - [Installing Marlin (VSCode)](http://marlinfw.org/docs/basics/install_platformio_vscode.html).
 
-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.
