 This project contains only files to build a build container image.
 
 ## golang

+To use this image for building golang applications execute this in your root
+folder of your go project.

 ```bash
 $ docker run \
     --rm \
     --volume ${PWD}:/workspace \
     volkerraschek/build-image:latest \
       go build

+## rust
+
+If you want to compile instead go rust sourcecode, than you can do it similar to the golang example.
+
+```bash
+$ docker run \
+    --rm \
+    --volume ${PWD}:/workspace \
+    volkerraschek/build-image:latest \
+      cargo build --release
