 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
