+# Quick Start Docker Images
+
+These Docker images are part of the quick start build environment.
+
+Documentation for developer reference only.
+
+To add another distribution; simply add a folder with a Dockerfile, and re-run the quick start configure script.
+
+## Prepare Ubuntu
+
+Just build the Docker images like this. The quick start scripts will generate the proper command line.
+
+```
+docker build -t "ryzombuild_bionic_x86_64" -f "Y:\ryzomcore4\code\tool\quick_start\docker\ryzombuild_bionic_x86_64\Dockerfile" Y:\ryzomcore4\code
+```
+
+```
+docker build -t "ryzombuild_focal_x86_64" -f "Y:\ryzomcore4\code\tool\quick_start\docker\ryzombuild_focal_x86_64\Dockerfile" Y:\ryzomcore4\code
+```
+
+## Prepare Steam Runtime
+
+```
+cd /d Y:\ryzomcore4\.nel\temp
