Update to latest chicken version

 development. An optional custom `chicken-assemble` script is also
 provided, used to build projects in an opinionated, structured way.
 
+You may pick a flavour built on top of popular linux distros:
+
+```bash
+docker pull plotter/chicken-scheme:5.2.0-alpine
+docker pull plotter/chicken-scheme:5.2.0-debian
+docker pull plotter/chicken-scheme:5.2.0-ubuntu
+docker pull plotter/chicken-scheme:5.2.0-centos
+```
+
 ## How to use these images
 
-TODO write decent examples
+Mount your source code directory into a running container to access
+chicken's REPL and/or compiler:
+
+```bash
+docker run --rm -it --workdir /src -v $(pwd):/src plotter/chicken-scheme
+```
+
+For truly static builds, prefer the `alpine` base image and set the
+proper compiler and linker flags:
+
+```dockerfile
+FROM plotter/chicken-scheme:5.2.0-alpine
+WORKDIR /src
+COPY . .
+RUN csc ... TODO write proper compilation instruction
+ENTRYPOINT ["/src/main"]
+```
+
+You may also choose to build a barebones `scratch` image containing
+only the desired binary:
+
+```dockerfile
+FROM plotter/chicken-scheme:5.2.0-alpine as build
+WORKDIR /src
+COPY . .
+RUN csc ... TODO write proper compilation instruction
+
+FROM scratch
+COPY --from=build /src/app /bin/app
+ENTRYPOINT ["/bin/app"]
+```
