-# 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
-```

-of actions.
