 ## Installation via dankinstall
 
-**Interactive (TUI):**
-
 ```bash
 curl -fsSL https://install.danklinux.com | sh
 ```
 
-**Headless (unattended):**
-
-Headless mode requires cached sudo credentials. Run `sudo -v` first:
-
-```bash
-sudo -v && curl -fsSL https://install.danklinux.com | sh -s -- -c niri -t ghostty -y
-sudo -v && curl -fsSL https://install.danklinux.com | sh -s -- -c hyprland -t kitty --include-deps dms-greeter -y
-```
-
-| Flag | Short | Description |
-|------|-------|-------------|
-| `--compositor <niri|hyprland>` | `-c` | Compositor/WM to install (required for headless) |
-| `--term <ghostty|kitty|alacritty>` | `-t` | Terminal emulator (required for headless) |
-| `--include-deps <name,...>` | | Enable optional dependencies (e.g. `dms-greeter`) |
-| `--exclude-deps <name,...>` | | Skip specific dependencies |
-| `--replace-configs <name,...>` | | Replace specific configuration files (mutually exclusive with `--replace-configs-all`) |
-| `--replace-configs-all` | | Replace all configuration files (mutually exclusive with `--replace-configs`) |
-| `--yes` | `-y` | Required for headless mode — confirms installation without interactive prompts |
-
-Headless mode requires `--yes` to proceed; without it, the installer exits with an error.
-Configuration files are not replaced by default unless `--replace-configs` or `--replace-configs-all` is specified.
-`dms-greeter` is disabled by default; use `--include-deps dms-greeter` to enable it.
-
-When no flags are provided, `dankinstall` launches the interactive TUI.
-
-### Headless mode validation rules
-
-Headless mode activates when `--compositor` or `--term` is provided.
-
-- Both `--compositor` and `--term` are required; providing only one results in an error.
-- Headless-only flags (`--include-deps`, `--exclude-deps`, `--replace-configs`, `--replace-configs-all`, `--yes`) are rejected in TUI mode.
-- Positional arguments are not accepted.
-
-### Log file location
-
-`dankinstall` writes logs to `/tmp` by default.
-Set the `DANKINSTALL_LOG_DIR` environment variable to override the log directory.
-
 ## Supported Distributions
 
 Arch, Fedora, Debian, Ubuntu, openSUSE, Gentoo (and derivatives)
