 ## Modernization
 
-The Electron team is currently undergoing an initiative to modernize our API in a few concrete ways. These include: updating our modules to use idiomatic JS properties instead of separate `getPropertyX` and `setPropertyX`, converting callbacks to promises, and removing some other anti-patterns present in our APIs. The current status of the Promise initiative can be tracked in the [promisification](promisification.md) tracking file.
+The Electron team is currently undergoing an initiative to modernize our API in a few concrete ways. These include: updating our modules to use idiomatic JS properties instead of separate `getPropertyX` and `setpropertyX`, converting callbacks to promises, and removing some other anti-patterns present in our APIs. The current status of the Promise initiative can be tracked in the [promisification](promisification.md) tracking file.
 
 As we work to perform these updates, we seek to create the least disruptive amount of change at any given time, so as many changes as possible will be introduced in a backward compatible manner and deprecated after enough time has passed to give users a chance to upgrade their API calls.

-
-These methods can be accessed from the `webFrameMain` module:
-
-### `webFrameMain.fromId(processId, routingId)`
-
-* `processId` Integer - An `Integer` representing the id of the process which owns the frame.
-* `routingId` Integer - An `Integer` representing the unique frame id in the
-  current renderer process. Routing IDs can be retrieved from `WebFrameMain`
-  instances (`frame.routingId`) and are also passed by frame
-  specific `WebContents` navigation events (e.g. `did-frame-navigate`).
-
-Returns `WebFrameMain` - A frame with the given process and routing IDs.
-
-## Class: WebFrameMain
-
-Process: [Main](../glossary.md#main-process)
-
-### Instance Methods
-
-#### `frame.executeJavaScript(code[, userGesture])`
-
-* `code` String
-* `userGesture` Boolean (optional) - Default is `false`.
-
-Returns `Promise<unknown>` - A promise that resolves with the result of the executed
-code or is rejected if execution throws or results in a rejected promise.
-
-Evaluates `code` in page.
-
-In the browser window some HTML APIs like `requestFullScreen` can only be
-invoked by a gesture from the user. Setting `userGesture` to `true` will remove
-this limitation.
-
-#### `frame.reload()`
-
-Returns `boolean` - Whether the reload was initiated successfully. Only results in `false` when the frame has no history.
-
-### Instance Properties
-
-#### `frame.url` _Readonly_
-
-A `string` representing the current URL of the frame.
-

-2> Fix the conflict and run gclient again.
