+### Running SDC together with DCR on local
+
+If you are making making changes in dotcom-rendering against support-dotcom-components, you will probably want to get your local version of DCR making its HTTP requests to the local version of SDC. For this start your local SDC, notice the port it's running at, and start your DCR with
+
+```
+SDC_URL=http://127.0.0.1:8082 make dev
+```
+
+with the correct value for the port.
