+NWB Extensions (NDX) Catalog
+============================
+
+The :ndx-catalog:`NDX Catalog website <>` contains published
+extensions created by the community to add support for a wide variety of data types.
+Before creating your own extension, we recommend that you explore the Catalog to
+make sure that someone has not already created an extension that suits your needs
+or that you could build off of.

+NWB Enhancement Proposals (NEPs)
+================================
+
+The NWB data standard is not static but evolves to adapt to changing needs from the neuroscience community, 
+clarify ambiguities, and fix bugs, among others. Users can propose smaller changes, such as improvements to
+documentation or addition of a new optional field to an existing data type, on the 
+:nwb-schema-src:`NWB Schema GitHub repository <>`. Users can propose larger changes, such as addition of 
+several new data types to support a new data modality, or a major restructuring of existing data types, 
+through NWB Enhancement Proposals (NEPs).
+
+NEPs are often collaborative and led by members of the community to address a significant need by the 
+community. Here is a list of NEPs that have been started:
+
+.. list-table:: NEPs

+
+To add a new NEP to this list, please file an issue on the :nwb-overview-src:`NWB Overview GitHub repo <>`
+or create a pull request that modifies the table.
+
+Review of NEPs for acceptance to the NWB core data standard is led by the 
+:nwb-tab:`NWB Technical Advisory Board (TAB) <>`
+and involves several phases. To submit a NEP for review and explore previous NEP reviews, see the 
+:nep-review:`NEP Review GitHub repo <>`. For more information on the NEP process, see the following links:
