+# Electron Dev on Codespaces
+
+Welcome to the Codespaces Electron Developer Environment.
+
+## Quick Start
+
+Upon creation of your codespace you should have [build tools](https://github.com/electron/build-tools) installed and an initialized gclient checkout of Electron.  In order to build electron you'll need to run the following commands.
+
+```bash
+e sync -vv
+e build
+```
+
+The initial sync will take approximately ~30 minutes and the build will take ~8 minutes.  Incremental syncs and incremental builds are substantially quicker.
+
+## Directory Structure
+
+Codespaces doesn't lean very well into gclient based checkouts, the directory structure is slightly strange.  There are two locations for the `electron` checkout that both map to the same files under the hood.
+
+```graphql
+# Primary gclient checkout container
+/workspaces/gclient/*
+  └─ src/* - # Chromium checkout
+     └─ electron - # Electron checkout
+# Symlinked Electron checkout (identical to the above)
+/workspaces/electron
+```
+
+## Goma
+
+If you are a maintainer [with Goma access](../docs/development/goma.md) it should be automatically configured and authenticated when you spin up a new codespaces instance.  You can validate this by checking `e d goma_auth info` or by checking that your build-tools configuration has a goma mode of `cluster`.
+
+## Running Electron
+
+You can run Electron in a few ways.  If you just want to see if it launches:
+
+```bash
+# Enter an interactive JS prompt headlessly
+xvfb-run e start -i
+```
+
+But if you want to actually see Electron you will need to use the built-in VNC capability.  If you click "Ports" in codespaces and then open the `VNC web client` forwarded port you should see a web based VNC portal in your browser.  When you are asked for a password use `builduser`.
+
+Once in the VNC UI you can open `Applications -> System -> XTerm` which will open a VNC based terminal app and then you can run `e start` like normal and Electron will open in your VNC session.
+
+## Running Tests
+
+You run tests via build-tools and `xvfb`.
+
+```bash
+# Run all tests
+xvfb-run e test
+
+# Run the main process tests
+xvfb-run e test --runners=main
+
+# Run the old remote tests
+xvfb-run e test --runners=remote
+```

For example, [Electron Fiddle](https://www.electronjs.org/fiddle) is a great tool for making small test cases and makes it easy to publish your test case to a [gist](https://gist.github.com) that Electron maintainers can use.

+            Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.
