+# 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
+```

+
+This can be configured to either restrict usage of non-encrypted DNS
+(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:

+
+To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do

-# Frameless Window
-
-> Open a window without toolbars, borders, or other graphical "chrome".
-
-A frameless window is a window that has no
-[chrome](https://developer.mozilla.org/en-US/docs/Glossary/Chrome), the parts of
-the window, like toolbars, that are not a part of the web page. These are
-options on the [`BrowserWindow`](browser-window.md) class.
-
-## Create a frameless window
-
-To create a frameless window, you need to set `frame` to `false` in
-[BrowserWindow](browser-window.md)'s `options`:
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ width: 800, height: 600, frame: false })
-win.show()
-```
-
-### Alternatives on macOS
-
-There's an alternative way to specify a chromeless window.
-Instead of setting `frame` to `false` which disables both the titlebar and window controls,
-you may want to have the title bar hidden and your content extend to the full window size,
-yet still preserve the window controls ("traffic lights") for standard window actions.
-You can do so by specifying the `titleBarStyle` option:
-
-#### `hidden`
-
-Results in a hidden title bar and a full size content window, yet the title bar still has the standard window controls (“traffic lights”) in the top left.
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hidden' })
-win.show()
-```
-
-#### `hiddenInset`
-
-Results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge.
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
-win.show()
-```
-
-#### `customButtonsOnHover`
-
-Uses custom drawn close, and miniaturize buttons that display
-when hovering in the top left of the window. The fullscreen button
-is not available due to restrictions of frameless windows as they
-interface with Apple's macOS window masks. These custom buttons prevent
-issues with mouse events that occur with the standard window toolbar buttons.
-This option is only applicable for frameless windows.
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover', frame: false })
-win.show()
-```
-
-## Windows Control Overlay
-
-On macOS, when using a frameless window in conjuction with `win.setWindowButtonVisibility(true)` or using one of the `titleBarStyle`s described above so
-that the traffic lights are visible, you can access the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and
-[CSS Environment Variables][overlay-css-env-vars] by setting the `titleBarOverlay` option to true:
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({
-  titleBarStyle: 'hiddenInset',
-  titleBarOverlay: true
-})
-win.show()
-```
-
-## Transparent window
-
-By setting the `transparent` option to `true`, you can also make the frameless
-window transparent:
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow({ transparent: true, frame: false })
-win.show()
-```
-
-### Limitations
-
-* You can not click through the transparent area. We are going to introduce an
-  API to set window shape to solve this, see
-  [our issue](https://github.com/electron/electron/issues/1335) for details.
-* Transparent windows are not resizable. Setting `resizable` to `true` may make
-  a transparent window stop working on some platforms.
-* The `blur` filter only applies to the web page, so there is no way to apply
-  blur effect to the content below the window (i.e. other applications open on
-  the user's system).
-* The window will not be transparent when DevTools is opened.
-* On Windows operating systems,
-  * transparent windows will not work when DWM is
-  disabled.
-  * transparent windows can not be maximized using the Windows system menu or by double clicking the title bar. The reasoning behind this can be seen on [this pull request](https://github.com/electron/electron/pull/28207).
-* On Linux, users have to put `--enable-transparent-visuals --disable-gpu` in
-  the command line to disable GPU and allow ARGB to make transparent window,
-  this is caused by an upstream bug that [alpha channel doesn't work on some
-  NVidia drivers](https://bugs.chromium.org/p/chromium/issues/detail?id=369209) on
-  Linux.
-* On Mac, the native window shadow will not be shown on a transparent window.
-
-## Click-through window
-
-To create a click-through window, i.e. making the window ignore all mouse
-events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
-API:
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-win.setIgnoreMouseEvents(true)
-```
-
-### Forwarding
-
-Ignoring mouse messages makes the web page oblivious to mouse movement, meaning
-that mouse movement events will not be emitted. On Windows operating systems an
-optional parameter can be used to forward mouse move messages to the web page,
-allowing events such as `mouseleave` to be emitted:
-
-```javascript
-const { ipcRenderer } = require('electron')
-const el = document.getElementById('clickThroughElement')
-el.addEventListener('mouseenter', () => {
-  ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
-})
-el.addEventListener('mouseleave', () => {
-  ipcRenderer.send('set-ignore-mouse-events', false)
-})
-
-// Main process
-const { ipcMain } = require('electron')
-ipcMain.on('set-ignore-mouse-events', (event, ...args) => {
-  BrowserWindow.fromWebContents(event.sender).setIgnoreMouseEvents(...args)
-})
-```
-
-This makes the web page click-through when over `el`, and returns to normal
-outside it.
-
-## Draggable region
-
-By default, the frameless window is non-draggable. Apps need to specify
-`-webkit-app-region: drag` in CSS to tell Electron which regions are draggable
-(like the OS's standard titlebar), and apps can also use
-`-webkit-app-region: no-drag` to exclude the non-draggable area from the
- draggable region. Note that only rectangular shapes are currently supported.
-
-Note: `-webkit-app-region: drag` is known to have problems while the developer tools are open. See this [GitHub issue](https://github.com/electron/electron/issues/3647) for more information including a workaround.
-
-To make the whole window draggable, you can add `-webkit-app-region: drag` as
-`body`'s style:
-
-```html
-<body style="-webkit-app-region: drag">
-</body>
-```
-
-And note that if you have made the whole window draggable, you must also mark
-buttons as non-draggable, otherwise it would be impossible for users to click on
-them:
-
-```css
-button {
-  -webkit-app-region: no-drag;
-}
-```
-
-If you're only setting a custom titlebar as draggable, you also need to make all
-buttons in titlebar non-draggable.
-
-## Text selection
-
-In a frameless window the dragging behavior may conflict with selecting text.
-For example, when you drag the titlebar you may accidentally select the text on
-the titlebar. To prevent this, you need to disable text selection within a
-draggable area like this:
-
-```css
-.titlebar {
-  -webkit-user-select: none;
-  -webkit-app-region: drag;
-}
-```
-
-## Context menu
-
-On some platforms, the draggable area will be treated as a non-client frame, so
-when you right click on it a system menu will pop up. To make the context menu
-behave correctly on all platforms you should never use a custom context menu on
-draggable areas.

+# safeStorage
+
+> Allows access to simple encryption and decryption of strings for storage on the local machine.
+
+Process: [Main](../glossary.md#main-process)
+
+This module protects data stored on disk from being accessed by other applications or users with full disk access.
+
+Note that on Mac, access to the system Keychain is required and
+these calls can block the current thread to collect user input.
+The same is true for Linux, if a password management tool is available.
+
+## Methods
+
+The `safeStorage` module has the following methods:
+
+### `safeStorage.isEncryptionAvailable()`
+
+Returns `boolean` - Whether encryption is available.
+
+On Linux, returns true if the app has emitted the `ready` event and the secret key is available.
+On MacOS, returns true if Keychain is available.
+On Windows, returns true once the app has emitted the `ready` event.
+
+### `safeStorage.encryptString(plainText)`
+
+* `plainText` string
+
+Returns `Buffer` -  An array of bytes representing the encrypted string.
+
+This function will throw an error if encryption fails.
+
+### `safeStorage.decryptString(encrypted)`
+
+* `encrypted` Buffer
+
+Returns `string` - the decrypted string. Decrypts the encrypted buffer
+obtained  with `safeStorage.encryptString` back into a string.
+
+This function will throw an error if decryption fails.
