+## Engine Versions
+
+When submitting code plugins to the Marketplace, you're only allowed to include
+a single supported `EngineVersion` in each version you upload. Even though you 
+don't submit built binaries to the Marketplace, the publisher portal requires
+that the .uplugin has a single `EngineVersion` entry.
+
+Therefore to support multiple engine versions, you have to upload several essentially
+identical source archives, with each one having a different `EngineVersion` specified
+in the .uplugin.
+
+This script helps you do that; for each entry in `EngineVersions` in the `pluginconfig.json`,
+a separate zip archive is generated, with the correct version set in the .uplugin.
+
+> It seems you should always use ".0" as the 3rd version digit.
