+# .NET for Apache Spark dev Docker image
+
+## Description
+
+This directory contains the source code to build a docker development image.
+Using this image, you can compile .NET for Apache Spark yourself.
+
+If you do not want to build those images yourself, you can get our pre-built images directly from docker hub at [https://hub.docker.com/r/3rdman/dotnet-spark](https://hub.docker.com/r/3rdman/dotnet-spark).
+
+## Building
+
+To build a dev image, just run the [build.sh](build.sh) bash script. The default Apache Spark and Maven versions used to build the image are defined in the script.
+
+You can also specify different versions, by using one of the following command line options:
+
+```bash
+ -a, --apache-spark
+ -m, --maven
+```
+
+For more details please run
+
+```bash
+build.sh -h
+```
+
+Please note, that not all version combinations are supported, however.
+
+## Docker Run Example
+
+As mentioned earlier, the dotnet-spark runtime image can be used in multiple ways. Below are some examples that might be useful.
+
+```bash
+docker run --name dotnet-spark-dev -d 3rdman/dotnet-spark:dev-latest
+```
+
+## Using the image to build from source
+
+- ### Docker interactive terminal
+
+The most basic way to build .NET for Apache Spark from source is to connect to the started container using the following docker command
+
+```bash
+docker exec -it dotnet-spark-dev bash
+```
+
+As the image comes with a clone of the GitHub repository already, just navigate into the local git repository folder and ensure that you have the most recent version of the source available.
+
+```bash
+cd ~/dotnet.spark
+git pull
+```
+
+Now you can start with [Building Spark .NET Scala Extensions Layer](https://github.com/dotnet/spark/blob/master/docs/building/ubuntu-instructions.md#building).
+
+If you prefer a more GUI based approach, there are a couple of options available as well.
+
+- ### Using [code-server](https://github.com/cdr/code-server)
+
+The image comes with code-server installed, which allows you run Visual Studio Code and build .NET for Apache Spark in a web-browser.
+
+First, start a container from the dev image and map the code-server port to a host port that is reachable via the loopback address only.
+
+```bash
+docker run --name dotnet-spark-dev -d -p 127.0.0.1:8888:8080 3rdman/dotnet-spark:dev-latest
+```
+
+
+
+Now use a web-browser to connect to http://127.0.0.1:8888. This will open Visual Studio Code in the browser. After opening the dotnet.spark repository folder and a new Terminal windows, you can with to the scala source folder and start the build process.
+
+```bash
+cd src/scala
+mvn clean package
+```
+
+
+
+- ### VS Code & remote containers
+
+You may also want to give the Docker- and Remote Containers extensions for Visual Studio Code a try
