+# Thanks for buying GoReleaser Pro! 🥳
+
+A few notes on how to get started:
+
+- [x] if you use GitHub Actions, make sure to set the `distribution` option to
+   `pro`. Don't forget to add the `GORELEASER_KEY` environment variable as
+   well.[^actions]
+- [x] if you installed GoReleaser via a package manager, you'll need to install a
+   different package. Usually it's the same name as the OSS, but with a
+   `-pro` suffix.[^install]
+- [x] Once you install the Pro version, you can set the `GORELEASER_KEY`
+   environment variable according to your shell of choice, and use it the same
+   way you use the OSS version — with all the extra features!
+- [x] If you use the YAML Language Server, check out the Pro Schema as
+  well.[^schema]
+- [x] If you have any questions or feedback, feel free to contact in the email you
+  received or on any of the public chats we have.[^links]
+
+I hope GoReleaser Pro helps improving your release workflow even more!
+
+Thank you!
