 # `odc_box`
 
-This repository hosts all you need to install an *Open Data Cube* instance as a docker container that serves a Jupyter notebook environment running a Python kernel and an R kernel. It is based on the [Cube-in-a-box](https://github.com/opendatacube/cube-in-a-box) project. The changes and additions include (i) a revised `Dockerfile`, adding instructions to install R, its upstream dependencies and connect it with the Jupyter environment, (ii) helper scripts for quick re-deploys of the container environment, (iii) a revised `README.md` and (iv) additional Python dependencies. See the commit history for all changes to the original repository.

+## Additional features
+
+* an R kernel and its upstream dependencies, initialized to connect with the Jupyter environment,
+* a pre-installed suite of R packages for spatial analysis as well as there system requirements
+* helper scripts for quick starting, stoping and re-deploying of the container environment (see below),
+* a revised `README.md` with installation instructions
