+# Privileges Manager
+
+A visual, searchable GUI for managing player privileges in Luanti (Minetest).
+Works on **Minetest Game** and **Mineclonia / VoxeLibre**, and can manage
+**offline players** as well as online ones.
+

+
+## Features
+
+- **Searchable player list** with a search bar — type part of a name and press
+  **Enter** (or click *Search*) to filter. Online players are shown first
+  (● green) above offline players (○ grey).
+- **Toggle switches** for every registered privilege. Click a switch to grant
+  (green **ON**) or revoke (grey **OFF**) instantly. Each switch shows the
+  privilege description as a tooltip.
+- **Offline player support** — every account known to the server's auth
+  database is listed, so you can adjust privileges for players who aren't
+  connected. You can also open any player by exact name (bottom-left field),
+  which works even for accounts that don't exist yet.
+- **Game-aware look** — the formspec uses real coordinates (formspec v4) and
+  adapts its palette to Minetest Game or the Mineclone family automatically.
+- **Respects the engine permission model** — you need the `privs` privilege to
+  manage any privilege, or `basic_privs` to manage only the privileges listed
+  in the `basic_privs` setting. Privileges you may not grant are shown locked
+  (🔒). Permissions are re-checked on the server for every toggle, so the GUI
+  can't be used to escalate privileges.
+
+## Usage
+
+- `/privman` — open the manager.
+- `/privman <player>` — open it with a player pre-selected.
+- `/privileges_manager` — alias for `/privman`.
+
+On games with **sfinv** (e.g. Minetest Game) a *Privileges* tab is added to the
+inventory for players who may use it. On games with **unified_inventory** a
+button is added too.
+
+## Notes
+
+- Granting a privilege to a name that has never logged in creates a new account
+  with the server's default password — exactly like the `/grant` command.
+- Changes take effect immediately; online players are notified in chat.
