 # drawing-robot-ros2
 
-## Building
+This repository contains ROS2 packages which make up a system used for drawing SVG images on different robots.
+These packages are in 'src/'.
+
+Documentation and build scripts for the entire project are at the top level.
+
+The simplest way to run the project currently is by building and running the docker container.
+
+## Docker
+### Build container
+
+``` sh
+bash .docker/build.bash
+```
+
+### Run built container
+``` sh
+bash .docker/run.bash
+```
+
+If active changes are being made, run:
+``` sh
+bash .docker/devel.bash
+```
+This will mount the host `drawing-robot-ros2` directory in the container at `src/drawing-robot-ros2`.
