 ## Install
 
+On a fresh Arch install, logged in as your own user with sudo and a network
+connection:

+```bash
+curl -fsSL https://git.sirblob.co/SirBlob/blomarchy/raw/branch/main/bootstrap.sh | bash

+
+`bootstrap.sh` installs `git`, clones this repository to `~/dotfiles` (or
+`BLOB_CHECKOUT_DIR`), and runs `install.sh`, passing any flags through with
+`bash -s -- --autologin`.

 `BLOB_PATH` is a symlink to this checkout, so `bin/`, `shell/`, `themes/` and
 `default/` are always the working tree and edits are live. Only the handful of
 files that must sit under `~/.config` get copied.
