+# Celix dev container usage
+
+This subdirectory contains a [Gitpod Containerfile](./Containerfile.gitpod) for developing on Celix using [Gitpod](https://gitpod.io/#https://github.com/apache/celix)
+and a [Ubuntu Containerfile](./Containerfile.ubuntu) for local development on Celix.
+
+The below steps only need to be executed if you want to develop locally, and not via Gitpod.
+
+## Build the celix-dev image yourself
+
+To always be able to develop on Celix with an up-to-date image, built the image yourself.
+
+```bash
+./container/build-ubuntu-container.sh
+```
+
+## Using the image
+
+### Start locally with SSH daemon
+
+```bash
+cd <project-root>
+
+# Start a local container with the SSH daemon running
+./container/start-ubuntu-container.sh
+```
+
+Now connect to the container via the remote container option of your favoured IDE and start building/developing.
+
+For example, you can now start with:
+
+* CLion connected to the container using [JetBrains Gateway](https://www.jetbrains.com/help/clion/remote-development-a.html)
+* CLion configured to connect to the container as [Remote Host](https://www.jetbrains.com/help/clion/remote-projects-support.html)
+
+When finished with development and testing, press `CTRL + \` to stop the SSH daemon and exit the container.
+
+### Start locally with only a bash shell
+
+The start script allows passing of additional paramters, which will override the starting of the SSH daemon.
+Execute the following commands to open a bash shell and build Celix from the command line:
+
+```bash
+cd <project-root>
+
+# Start a local container and open a bash shell
+./container/start-ubuntu-container.sh bash
+
+# Build Apache Celix
+mkdir celix-build
+cd celix-build
+../container/support-scripts/build-all.sh
+make -j
+
+# Run the unit tests for Apache Celix
+ctest --output-on-failure
+```
