+## What is Nit?
+
+Nit is an expressive language with a script-like syntax, a friendly type-system and aims at elegance, simplicity and intuitiveness.
+
+Nit has a simple straightforward style and can usually be picked up quickly, particularly by anyone who has programmed before.
+While object-oriented, it allows procedural styles.

+
+## How to use this image
+
+You can use these images to build then run your programs.
+
+### Experimenting with Nit
+
+~~~
+host$ docker run -ti nitlang/nit
+root@ce9b671dd9fc:/root/nit# nitc examples/hello_world.nit
+root@ce9b671dd9fc:/root/nit# ./hello_world
+hello world
+~~~
+
+### Build and Run Programs
+
+In your Dockerfile, write something like:
+
+~~~Dockerfile
+FROM nitlang/nit
+
+# Create a workdir
+RUN mkdir -p /root/work
+WORKDIR /root/work
+
+# Copy the source code in /root/work/
+COPY . /root/work/
+
+# Compile
+RUN nitc src/hello.nit --dir . \
+ # Clear disk space
+ && ccache -C
+# You can also use a Makefile or any build system you want.
+
+# Run
+CMD ["./hello"]
+~~~
+
+Then, build and execute
+
+~~~
+host$ docker build -t nithello .
+host$ docker run --rm nithello
+hello!
+~~~
+
+See the full example at <https://github.com/nitlang/nit/blob/master/misc/docker/hello/Dockerfile>
