Optional misc. on requirements documentation

[SamGG]

The documentatio is very clear. Great!

Here a few feedbacks to improve if you want:

• curl was not installed in Debian distribution (within Windows)
  => apt-get install curl
• the first shell command of some blocks start with a space, which results in the command not being stored in the bash history
• add a command to carry out the tip: "Make sure that the $HOME/.local/bin folder is in your $PATH variable."
  => the command is export PATH="$HOME/.local/bin:$PATH" and should be either executed in the shell (temporary solution) or added to .bashrc (definitive solution)

I hope I will enjoy contributing to a task :-)
