"AutoBuildMarlin" is a *Visual Studio Code* extension that provides a one-button interface to build and upload Marlin Firmware to your selected `MOTHERBOARD`, removing the need to edit your `platformio.ini` file or scroll through a long list of Marlin environments.
Before you install AutoBuildMarlin you'll first need to [Install PlatformIO in VSCode](http://marlinfw.org/docs/basics/install_platformio_vscode.html). Once you have followed these instructions, continue below.
- Open up the downloaded *Marlin Firmware* project folder (***NOT the "Marlin" folder within***) in *Visual Studio Code*. (You may also use the **Import Project…** option from the "PlaformIO Home" page.)
- Click the **Marlin Auto Build** icon ![AutoBuild Icon](https://github.com/MarlinFirmware/Marlin/raw/bugfix-2.0.x/buildroot/share/vscode/AutoBuildMarlin/img/AB_icon.png) in the Activities Bar (on the left side of *Visual Studio Code* window) to bring up the **Marlin Auto Build** options bar.
