+## Agenda
+* Onboarding docs/process -- Now is a great time to refine Electron onboarding
+    * build instructions:
+        * [GN](https://github.com/electron/electron/blob/master/docs/development/build-instructions-gn.md)
+        * [Linux](https://github.com/electron/electron/blob/master/docs/development/build-instructions-linux.md)
+        * [macOS](https://github.com/electron/electron/blob/master/docs/development/build-instructions-macos.md)
+        * [Windwos](https://github.com/electron/electron/blob/master/docs/development/build-instructions-windows.md)
+    * Current onboarding process:
+        * @ckerr - nightmare-ish because chromium's codebase is massive. No onboarding documentation.
+        * Need someone to pair with to get started
+    * [GitHub WIP intern guide](https://github.com/electron/intern-guide/)
+        * A private repo but `wg-outreach` members have been added
+        * This is an early WIP document for onboarding the GitHub Electron interns in June, but it could be revised to be a general-purpose onboarding doc
+    * TODO items:
+        * step 1: build electron
+            * [ ] @sofianguy test macOS
+            * [ ] @cruzerld test Linux
+            * [ ] @jdalton test Windows
+* https://github.com/electron/electron/issues/17429 
+    * @ckerr will talk to @zeke about this issue
