+# Build your own Docker image
+
+The docker-custom directory contains files you need to build your own images.
+
+The steps to take to build your own images are:
+
+1) **package.json**
+
+   - Change the node-red version in package.json (from the docker-custom directory) to the version you require
+   - Add optionally packages you require
+
+2) **docker-make.sh**
+
+   Change the build arguments as needed:
+
+   - `--build-arg ARCH=amd64` : architecture your are building for (arm32v6, arm32v7, arm64v8, amd64)
+   - `--build-arg NODE_VERSION=10` : NodeJS version you like to use
+   - `--build-arg NODE_RED_VERSION=${NODE_RED_VERSION}` : don't change this, ${NODE_RED_VERSION} gets populated from package.json
+   - `--build-arg OS=alpine` : the linux distro you like to use (alpine or buster-slim)
+   - `--build-arg BUILD_DATE="$(date +"%Y-%m-%dT%H:%M:%SZ")"` : don't change this
+   - `--build-arg PYTHON_VERSION=0` : add Python to your image (0=no Python, 2=Python 2.x, 3=Python 3.x) 
+   - `--file Dockerfile-alpine.custom` : Dockerfile to use to build your image (Dockerfile-alpine.custom or Dockerfile-slim.custom)
+   - `--tag mynodered:node-red-custom-build` : set the image name and tag
+
+3) **Run docker-make.sh**
+
+```
+$ ./docker-make.sh
+```
+
+This starts building your custom image and might take a while depending on the system you are running on.
+
+When building is done you can run it by the following command:
+
+```
+$ docker run -it -p1880:1880 mynodered:node-red-custom-build
+```
+
