+# NIH-plug: cargo subcommand for bundling plugins
+
+This is NIH-plug's `cargo xtask` command, as a `cargo` subcommand. This way you
+can use it outside of NIH-plug projects. If you're using NIH-plug, you'll want
+to use the xtask integration directly instead, see:
+<https://github.com/robbert-vdh/nih-plug/tree/master/nih_plug_xtask>.
+
+Since this has not yet been published to `crates.io`, you'll need to install
+this using:
+
+```shell
+cargo install --git https://github.com/robbert-vdh/nih-plug.git cargo-nih-plug
+```
