+
+IPTVnator is a free, open-source **IPTV player**. It does **not** provide, sell, or
+manage IPTV subscriptions, channels, playlists, accounts, or streaming services.
+It only opens playlists you already have.
+
+Recently, several websites and "services" have started using the IPTVnator name to
+sell IPTV subscriptions or push suspicious downloads. This post clarifies what is
+official and how to stay safe.
+
+<Alert type="warning" title="None of these are affiliated with IPTVnator">
+  Any site selling "IPTVnator subscriptions", "IPTVnator channels", "premium",
+  "activated", or "cracked" IPTVnator, or paid TV packages under the IPTVnator name,
+  is **not** connected to this project or its maintainer.
+</Alert>
+
+## Official sources — the only ones
+
+- **Landing page & blog:** https://4gray.github.io/iptvnator/
+- **Source code:** https://github.com/4gray/iptvnator
+- **Downloads (releases):** https://github.com/4gray/iptvnator/releases
+
+If a link is not on this list, treat it as unofficial.
+
+## How to stay safe
+
+Be especially careful if any website asks you to:
+
+- copy and paste commands into your terminal, or run them with admin privileges
+- enter your administrator password to "install" the app
+- download `.dmg`, `.pkg`, `.exe`, or `.AppImage` files from an unofficial source
+- disable your operating system's security warnings
+- get a "premium", "cracked", or "activated" IPTVnator build
+
+<Alert type="info" title="A note on terminal commands">
+  IPTVnator itself never needs a subscription or an activation step. The only
+  terminal command we ever recommend is documented here on the official blog (for
+  the macOS "app is damaged" fix). If a command comes from anywhere else, do not run it.
+</Alert>
+
+## IPTVnator is not an IPTV provider
+
+There is no official IPTVnator subscription, channel list, streaming account, or
+paid support. Anyone selling those under the IPTVnator name does not represent this
+project.
+
+If you are ever unsure whether something is official, start from the links above.
