+# Accessing Data in the Philanthropy Data Commons Using the API
+
+This section describes using the PDC API to view or send data to the PDC. There
+may be multiple ways to accomplish this in future.
+
+To use the PDC API to view changemaker data, see the [OpenAPI documentation for
+the `GET /changemakers` endpoint
+](https://api.philanthropydatacommons.org/#/Changemakers/getChangemakers). No
+authentication is required to view changemaker data.
+
+To see more data or add data to the Philanthropy Data Commons, you will need a
+User in the PDC system. Please use the [Contact
+form](https://philanthropydatacommons.org/contact/) to describe your PDC user
+story and that you would like to be added to the PDC.
+
+# Sending Data to the Philanthropy Data Commons Using the API
+
+Get a User that can log in as described above.
+
+Familiarize yourself with the central PDC service API by visiting the [OpenAPI
+documentation at the PDC](https://api.philanthropydatacommons.org). The related
+[(aspirational) Entity Relation Diagram
+](https://github.com/PhilanthropyDataCommons/service/blob/main/docs/ENTITY_RELATIONSHIP_DIAGRAM.md)
+helps see how data are modeled.
+
+Use the "Authorize" button in the upper right and click "Authorize" again (no
+changes on the form are needed) to log in to the PDC.
+
+Use the [`POST /proposalVersions` endpoint
+](https://api.philanthropydatacommons.org/#/Proposals/addProposalVersion)
+to add data. Of course, there are multiple other things to add prior to using
+this endpoint, as you can see in the required parameters here and the required
+parameters of the related endpoints.
