+## Installing on silverstripe/recipe-cms < 4.11
+
+The 4.8 - 4.10 releases of `recipe-cms` support both versions `3` and `4.0.0-alpha` versions of this module. Using the alpha (or beta) releases requires inlining the recipe and updating the `silverstripe/graphql` version.
+
+You can inline silverstripe/recipe-cms by running this command:
+
+```
+composer update-recipe silverstripe/recipe-cms
+```
+
+Alternatively, you can remove `silverstripe/recipe-cms` from your root `composer.json` and replace it with the the contents of the `composer.json` in `silverstripe/recipe-cms`.
