 ## VST3 Licensing Note
 
-You must accept Steinberg's VST3 SDK licence before distributing VST3 binaries.
-NIH-plug's VST3 bindings are GPLv3; if you distribute, the plugin must also be GPLv3
-(or you need a commercial Steinberg licence). CLAP has no such restriction.
+NIH-plug's VST3 bindings (`vst3-sys`) are GPLv3. Linking them makes the resulting binary
+GPLv3 regardless of what `Cargo.toml` declares, so **VST3 is behind an opt-in `vst3` feature
+and this template builds CLAP only by default.** That keeps the default build consistent with
+the Apache-2.0 licence in `Cargo.toml`/`LICENSE`.
+
+If you want to ship a VST3:
+
+1. Build with `--features vst3`.
+2. Relicense your plugin as GPLv3 (or obtain a commercial Steinberg licence) and update
+   `Cargo.toml`, `LICENSE`, and the SPDX headers in `src/`.
+3. Accept Steinberg's VST3 SDK licence.
+
+CLAP has no such restriction.
