-Since Google Keep doesn't allow the use of iframes, this plugin gets creative by adding a [BrowserView](https://www.electronjs.org/docs/latest/api/browser-view) for the Google Keep view. However, since they render on top of everything else, the view has to be hidden whenever a modal or menu is open. It's a compromise.
+If you accidentally close the Google Keep view, or it doesn't open when you first install the plugin, you can open it again with the `Obsidian Keep: Open Keep` command.
 
-The plan is that, once the official [Google Keep API](https://developers.google.com/keep) is farther along and has an official JavaScript API, this plugin will start using that instead.

-## Manual Installation
-- Go to the [latest release](https://github.com/Ellpeck/ObsidianKeep/releases) here on GitHub
-- Download `obsidian-keep.zip`
-- Extract `obsidian-keep.zip` into your vault's `.obsidian/plugins` folder so that the resulting `obsidian-keep` folder contains the `main.js` and `manifest.json` files
-- Go into Obsidian and enable the plugin in the Community Plugins section
+By default, the plugin also ships with a set of custom CSS that is applied to Google Keep to make it work better as a narrow side view rather than a full page.
