+# Useful links
+
+Useful links when learning about the VS Code sourcecode:
+
+## Getting started
+
+- VSCode UI guide (describes what sidebar, aux bar, panels, etc are. intended for general public), and UX guide (for developers)
+https://code.visualstudio.com/docs/getstarted/userinterface
+https://code.visualstudio.com/api/ux-guidelines/overview
+
+
+- Files you need in an extension
+https://code.visualstudio.com/api/get-started/extension-anatomy
+
+
+## Contributing
+
+VERY USEFUL - How VS Code's sourcecode is organized (describes entry point files, what browser/ and common/ mean, etc, read the whole thing!)
+- https://github.com/microsoft/vscode/wiki/Source-Code-Organization
+
+
+- Full VSCode API (all functions/events/variables available in extension api - look on right hand side for organization)
+https://code.visualstudio.com/api/references/vscode-api
+(don't miss this part on cancellation tokens, how events and disposables work) https://code.visualstudio.com/api/references/vscode-api#api-patterns
+
+
+- Guide on contributes ("contributes": part of package.json) - a "contribute" is how your extension mounts - it's all the things your extension actually contributes
+https://code.visualstudio.com/api/references/contribution-points
+(full package.json schema) https://code.visualstudio.com/api/references/extension-manifest
+(activation events you can define in package.json) https://code.visualstudio.com/api/references/activation-events
+
+
+- Every command built-in to VSCode (e.g. 'workbench.action.openWalkthrough')
+https://code.visualstudio.com/api/references/commands

+
+
+## Summary
+
+Editor:
+/vs/editor/contrib = allowed to depend on browser env
+/vs/editor/{common|browser} = core code ('common' and 'browser' are the only two envs that are allowed here)
+/vs/editor/{standalone} = seems unimportant - something about the standalone editor
+
+
+Workbench:
+/vs/workbench/contrib:
+    - no deps from outside here are allowed
+    - each contrib needs a single contribname.contribution.ts which serves as the entrypoint (eg /search/browser/search.contribution.ts)
+    - the contribution should expose its internal api from only 1 entrypoint and only be accessed from there, nowhere else (eg /search/common/search.ts)
+      - sounds like all services, etc should be managed by that one entrypoint
+/vs/workbench/api = provides vscode.d.ts to iinterface with stuff outside of /workbench/contrib
+/vs/workbench/{common|browser|electron-sandbox} = core code, "as minimal as possible"
+
+TODO andrew finish writing the summary from written notes (some visuals...)
