+## <a id="build-docker"></a>Build in Docker
+
+To build for Linux, you can alternatively build VSCodium in docker
+
+Firstly, create the container with:
+```
+docker run -ti --volume=<local vscodium source>:/root/vscodium --name=vscodium-build-agent vscodium/vscodium-linux-build-agent:bionic-x64 bash
+```
+
+When inside the container, you can use the following commands to build:
+```
+curl -fsSL https://deb.nodesource.com/setup_12.x | sudo -E bash -
+sudo apt-get install -y nodejs
+
+npm install -g yarn
+
+git clone https://github.com/VSCodium/vscodium.git
+
+cd vscodium
+
+./get_repo.sh
+
+export SHOULD_BUILD=yes
+export OS_NAME=linux
+export VSCODE_ARCH=x64
+
+./build.sh
+```
