 This container has the necessary FLOS tools installed inside it to generate bitstreams from your VHDL code. 
 However, to automate the bitstream generation process, you can generate a shell/bash script \textit{(.sh)}.
 This script will be executed inside the container and will perform all the steps to generate the bitstream using the internal FLOS tools installed in it.

 With this command you can execute several commands inside the open terminal by concatenating them through \textit{\&\&} symbol.
