+# Ah ah ah, you didn't say the magic word
+
+This `gtklock` module listens for failed unlock attempts and recreates Dennis Nedry’s “ah ah ah” lockout scene from Jurassic Park.
+
+*   **Animation:** Spawns a looping "Nedry" sprite at a random location on the screen.
+*   **Audio:** Plays the "ah ah ah, you didn't say the magic word" clip.
+*   **Safety:** Sprites avoid overlapping a configurable "deadzone" (e.g., your login box).
+*   **Performance:** Uses pre-warmed audio players for low latency and scaled images to fit any screen.
+
+## Requirements
+
+*   **Build:** Meson, Ninja, Rust (Cargo), GTK+3 development headers.
+*   **Runtime:** `gtklock`, `gstreamer`, `gst-plugins-base`, `gst-plugins-good` (for audio playback).
+
+## Build & Install
+
+1.  **Install Dependencies (Arch Linux example):**
+    ```bash
+    sudo pacman -S meson ninja rust gtk3 gstreamer gst-plugins-base gst-plugins-good gst-libav
+    ```
+
+2.  **Build:**
+    ```bash
+    meson setup builddir
+    meson compile -C builddir
+    ```
+
+3.  **Install:**
+    ```bash
+    sudo meson install -C builddir
+    ```
+
+## Usage
+
+Run `gtklock` with the module path:
+
+```bash
+gtklock -m /usr/lib/gtklock/ahfail-module.so
+```
+
+### Arguments
+
+*   `--deadzone=X,Y,W,H`: Defines a rectangle where sprites will *not* spawn (e.g., to keep your password field visible).
+    ```bash
+    gtklock -m ahfail-module.so -- --deadzone=860,440,200,200
+    ```
+    *(Note the `--` separator before module arguments)*
+
+*   `--audio-uri=URI`: Override the default audio clip.
+    ```bash
+    gtklock -m ahfail-module.so -- --audio-uri=file:///home/user/custom.mp3
+    ```
+
+## Development
+
+*   **Run Tests:** `cargo test`
+*   **Benchmarks:** `cargo test --test benchmarks -- --nocapture`
+*   **Linting:** `cargo clippy`
+
+## Customization
+
+To change the default sprite or audio:
+1.  Replace files in `assets/`.
+2.  Update `assets/ahfail.gresource.xml`.
+3.  Rebuild with Meson.
