+# SharePoint Framework development tools and libraries
+
+As the SharePoint Framework evolves, so do the various development tools and libraries that it uses.
+
+## SharePoint Framework version compatibility
+
+Because SharePoint Online and the on-premises versions of SharePoint Server have different release cycles for new capabilities, they also have support different Sharepoint Framework capabilities.
+
+SharePoint Online always uses the latest version of the SharePoint Framework, but SharePoint 2016 and SharePoint 2019 only support the versions that match the server-side dependencies of the deployed packages.
+
+|SharePoint version|Supported SPFx version|Supported features
+|---|---|---|
+|SharePoint Online|All versions|All features
+|SharePoint Server 2019|v1.4.1 or lower|SPFx client-side web parts in classic and modern pages, and extensions in modern pages.
+|SharePoint 2016 Feature Pack 2|v1.1|SPFx client-side web parts hosted in classic SharePoint pages.
+
+For more information about SharePoint Framework development with SharePoint 2016 Feature Pack 2 and SharePoint 2019, refer to the following:
+
+* [SharePoint Framework development with SharePoint 2016 Feature Pack 2](sharepoint-2016-support.md)
+* [SharePoint Framework development with SharePoint Server 2019](sharepoint-2019-support.md)
+
+## SPFx development environment compatibility
+
+As each new version of the SharePoint Framework is released, support for newer versions libraries is constantly added to ensure that the toolset remains up-to-date.
+
+The following table lists each version of SharePoint Framework along with each library versions are compatible:
