+---- about this neovim-configuration
+
+-- - features: completion, lsp, tree-sitter, formatter, automatic configuration of indendation.
+-- - goals: web development with typescript and tsx.
+-- - themes: on mac, one-light; otherwise, gruvbox.
+
+---- external setup
+
+-- - install git and neovim. e.g., with guix as package-manager, run:
+--   guix install git neovim
+-- - install "lazy" as neovim-specific package-manager:
+--   git clone --filter=blob:none --branch=stable https://github.com/folke/lazy.nvim.git ~/.local/share/nvim/lazy/lazy.nvim
+-- - install code-formatter and language servers using npm:
+--   npm i -g prettier typescript typescript-language-server vscode-langservers-extracted
