Note: According to the first link it is required to clone the packer stuff locally. This is done on MacOS and Windows in a slightly different way. Consult https://github.com/wbthomason/packer.nvim#quickstart on details.

Hint: On Unix use

git clone --depth 1 https://github.com/wbthomason/packer.nvim\
   ~/.local/share/nvim/site/pack/packer/start/packer.nvim

At first start there will be error messages. Ignore them, run ':PackerInstall' and quit and restart nvim.

Install nvim on Debian from source:

git clone https://github.com/neovim/neovim
sudo apt install ninja-build gettext cmake unzip curl
make CMAKE_BUILD_TYPE=Release
sudo make install
