-## Why should I lazy-load my content?
-
-The loading of contents on web page may make your load speed more slow, no one likes staring at a blank white page; users are impatient and will leave quickly.
-
-Lazy loading content on web page can help reduce resource contention and improve performance.
-
-
-## Why should I use this plugin?
-
-This plugin supports you to handle some common tips to help your website optimize the download of on-page resources.
-
-These tips are published at [following website](https://web.dev/) by Google Developers, if you are interested you can consult to understand more about website optimization.
-
-You can also manually implement these tips your-self, but it takes a lot of time and requires a lot of expertise.
-
-
-## How does this plugin work?
-
-This plugin helps you to optimize everything like image tags, video, audio, iframes as well as stylesheets, and JavaScript.
-
-This plugin incorporates tips used a lot by experienced web experts, as well as making the most of the latest web technologies in lazy-loading resources on the page.
-
-Among them are creating "data-src" attributes to laza-load the media, even the [loading="lazy" feature](https://web.dev/browser-level-image-lazy-loading/) recently introduced by Google Developers.
-
-
-## High performance and accuracy
-
-In addition, this plugin uses DOM to process the website structure so it produces accurate results and is faster than any other plugin that uses HTML text processing.
-
-You can give it a try and I believe you will be surprised by the results it brings to your website.
-
-
-## Stable performance and high compatibility
-
-We have tested this plugin with quite a few others and have not found any significant conflicts.
-
-For best use of this plugin, you should consider disabling all optimization features (Eg. lazy-loading, HTML minification, JS minification, etc.) by other plugins.
-
-We recommend you use it with another page-caching plugin for best performance.
