 ### Brief description
 
-The base image here is the popular `ubuntu:22:04` - that is to increase the similarity of the container system to users OSs; A few system tools come pre-installed: [GNU Bash](https://www.gnu.org/software/bash/), [gcc & g++](https://gcc.gnu.org/), [Git](https://git-scm.com/), [GNU Make](https://www.gnu.org/software/make/), [CMake](https://cmake.org/), [Vim](https://www.vim.org/) and most importantly - [mambaforge](https://github.com/conda-forge/miniforge), which has been set up for the (default) root user; port `8888` is exposed to the host machine; dir `/workspace` is available to mount a volume; an entrypoint script has been designed to add a new non-root linux user which can access conda via a system's group; executing commands as `angryuser` is available through [gosu](https://github.com/tianon/gosu).
