-### Settings
+For further infos, please [read the docs](https://math2001.github.io/MarkdownLivePreview/)!
-
-- `markdown_live_preview_on_open`: if set to `true`, as soon as you open a markdown file, the
-preview window will popup (thanks to[@ooing](https://github.com/ooing) for its
-[suggestion](https://github.com/math2001/MarkdownLivePreview/issues/7#issue-199464852)). Default to
-`false`
-- `load_from_internet_when_starts`: every images that starts with any of the string specified in
-this list will be loaded from internet. Default to `["http://", "https://"]`
-
-Note: To edit your settings, search up in the command palette
-`Preferences: MarkdownLivePreview Settings`, or by using the menu:
-*Preferences → Packages Settings → MarkdownLivePreview → Settings*;. It's not your global settings,

-
-### Syntax Specific Settings
-
-This in an other "type" of setting. :laughing: If you have a look at the syntax of the preview file
-(not the markdown one, really the preview), you'll see that the syntax is
-`MarkdownLivePreviewSyntax`. This mean that you can specify specific settings for this specific
-syntax (such as `word_wrap: true`, `rulers: []`, etc).
-
-To do so, you can
-
-1. focus the *preview* (<kbd>ctrl+2</kbd> to focus the second group, so, by default, the
-preview's group)
-2. search up in the command palette `Preferences: Settings Syntax Specific`. It's in the *right*
-file that you can add the settings you want (not the left one).
-
-Note: MarkdownLivePreview will actualy look in this file for settings that aren't supported by
-default. Here they are:
-
-- `show_tabs`
-- `show_minimap`
-- `show_status_bar`
-- `show_sidebar`
-- `show_menus`
-
-They talk for themself, don't they? All of them takes a boolean (`true` or `false`). Note that those
-settings are *window* specific, not just view specific (that's why they aren't supported). It means
-that they'll affect the entire window, and every view in it.
-
-Here is an example of syntax specific settings for MarkdownLivePreviewSyntax:
-
-```json
-{
-    "show_menus": false,
-    "show_tabs": false,
-    "show_minimap": false,
-    "gutter": false,
-    "rulers": [],
-    "word_wrap": true
-}
-```

-### Clear the cache
-
-MarkdownLivePreview caches every images it loads from internet (otherwise, you'd never see your
-images, or you'd need to have a *really* fast internet connection :smile:). So, if for some reason
