+# LibJava-Skycoin .NET  CLI development image
+
+This image has the necessary tools to build, test, edit, lint and version the Libskycoin .NET
+source code.  It comes with Vim editor installed, along with some plugins
+to ease go development and version control with git.
+
+# How to use this image
+
+## Initialize your development environment.
+
+```sh
+$ mkdir src
+$ docker run --rm \
+    -v ${PWD}/src:/usr/local/src skycoin/skycoindev-java:develop \
+    git clone https://github.com/simelo/libjava-skycoin.git \
+$ sudo chown -R `whoami` src
+```
+
+This downloads the libjava source to src/libjav and changes the owner
+to your user. This is necessary, because all processes inside the container run
+as root and the files created by it are therefore owned by root.
+
+## Running commands inside the container
+
+You can run commands by just passing the them to the image.  Everything is run
+in a container and deleted when finished.
+
+### Running tests
+
+```sh
+$ docker run --rm \
+    -v ${PWD}/src:/usr/local/src simelotech/skycoindev-java:develop \
+    sh -c "cd libskycoin-java; make test"
+```
+
+### Editing code
+
+```sh
+$ docker run --rm \
+    -v ${PWD}/src:/usr/local/src simelotech/skycoindev-java:develop \
+    vim
+```
+
