-weechat-notify 2, implemented as a native plugin instead of a script with a library.
+[weechat-notify](https://git.karx.xyz/karx/weechat-notify), implemented as a native plugin instead of a script with a library.
+
+requires: rust, notify-send
+
+to build, first run `cargo build --release` then move the generated .so (`target/release/libweechat_notify.so`) to your plugin directory (probably `~/.local/share/weechat/plugins` but could also be `~/.weechat/plugins`). then rename the .so to `weechat_notify.so`
+
+next, run `/plugin load weechat_notify` and enjoy your notifications!
+
+note: changes to the plugin are not reflected until you restart WeeChat.
