+## Intended use
+The repository mirrors the layout of `$HOME`: every file here lives at the same relative path it
+should have in the home directory (`.bashrc` → `~/.bashrc`, `.config/nvim` → `~/.config/nvim`, ...).
+The whole repository is a single [GNU Stow](https://www.gnu.org/software/stow/) package, so
+installing the dotfiles is just a matter of symlinking it into `$HOME`. Files that belong to the
+repository rather than to `$HOME` are listed in `.stow-local-ignore`.
+
+Machine-specific settings are kept out of the repository and loaded from local files instead, e.g.
+`~/.gitconfig.local` (see `.gitconfig.local.example`) and `.config/sway/config.local`.
+
+## Installation
+```sh
+# Install stow (Debian / Fedora)
+sudo apt install stow   # or: sudo dnf install stow
+
+# Clone into your home directory, including submodules (kitty themes, i3blocks-contrib)
+git clone --recurse-submodules <repo-url> ~/dotfiles
+cd ~/dotfiles
+
+# Symlink everything into $HOME
+stow -t ~ .
+
+# Local git settings, e.g. commit signing key
+cp .gitconfig.local.example ~/.gitconfig.local
+```
+
+Stow refuses to overwrite existing files. If a config already exists in `$HOME`, remove or back it
+up first, or use `stow --adopt -t ~ .` to move the existing file into the repository and review the
+result with `git diff`.
+
+### Updating
+Pull the changes and restow to pick up new or removed files:
+```sh
+git pull --recurse-submodules
+stow -R -t ~ .
+```
+
+### Uninstalling
+```sh
+stow -D -t ~ .
+```
