Open NeoVim (nvim command) and it will continue the installation by itself. Wait for it to finish... and done! You now have your new shiny powerful NeoVim
Optional: If you want fancy symbols and breadcrumbs on your status line and fancy icons for your files explorer, check this small tutorial.
Docker: Federico Gonzalez (FedeG) made a docker image which runs vim with this config inside, you can find it here or in docker hub.
¶ Fancy symbols
Airline allows you to use fancy symbols on the status line for breadcrumbs and indicators (examplej a padlock when editing read-only files).
And vim-devicons also has fancy symbols for the files in NERDTree (the file explorer), like a python logo for python files, etc.
Using them requires having a patched font in your terminal.
It may sound like black magic, but it's just downloading, installing and using a font from this website:
Nerd Fonts NerdFonts
git clone https://github.com/ryanoasis/nerd-fonts.git
I recommend just manually downloading the one you like the most from this list.
Configure
After installing the font, go to the settings of your terminal app and select the patched font. Finally, open your init.vim and uncomment:
the line declaring the vim-devicons plugin (search for "Nice icons")
the lines at the end of the file, after the comment that explains that those are the lines for the fancy symbols.
That's it! Restart your vim and enjoy the beauty of a modern terminal 
export EDITOR="nvim"
