-The startup template for [**Jekyll Theme Chirpy**][chirpy].
+When installing the [**Chirpy**][chirpy] theme through [RubyGems.org][gem], Jekyll can only read files in the folders
+`_data`, `_layouts`, `_includes`, `_sass` and `assets`, as well as a small part of options of the `_config.yml` file
+from the theme's gem. If you have ever installed this theme gem, you can use the command
+`bundle info --path jekyll-theme-chirpy` to locate these files.
 
-When installing the Chirpy through [RubyGems][gem], Jekyll can only read files in the folders `_includes`, `_layout`, `_sass` and `assets`, as well as a small part of options of the `_config.yml` file from the theme's gem (use the command `bundle info --path jekyll-theme-chirpy` to locate). To fully use all the features of Chirpy, you also need to copy other critical files/directories from the theme's gem to your Jekyll site.
+The Jekyll team claims that this is to leave the ball in the user’s court, but this also results in users not being
+able to enjoy the out-of-the-box experience when using feature-rich themes.
+
+To fully use all the features of **Chirpy**, you need to copy the other critical files from the theme's gem to your
+Jekyll site. The following is a list of targets:
 
 ```shell
-# The critical files/directories to run Chirpy theme
-├── _data
+.
+├── _config.yml
 ├── _plugins
 ├── _tabs
-├── _config.yml
-├── app.js
-├── feed.xml
-├── index.html
-├── robots.txt
-├── sw.js
-└── 404.html
+└── index.html
 ```
 
-We extracted all the necessary content of **Chirpy** theme's gem to help you quickly use the theme.
+To save you time, and also in case you lose some files while copying, we extract those files/configurations of the
+latest version of the **Chirpy** theme and the [CD][CD] workflow to here, so that you can start writing in minutes.
+
+## Prerequisites
+
+Follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of
+the basic environment. [Git](https://git-scm.com/) also needs to be installed.
 
 ## Installation
 
-[Use this template][usetemplate] to generate a new repository, and then execute:
+Sign in to GitHub and [**use this template**][use-template] to generate a brand new repository and name it
+`USERNAME.github.io`, where `USERNAME` represents your GitHub username.
 
-[usetemplate]: https://github.com/cotes2020/chirpy-starter/generate
+Then clone it to your local machine and run:
 
-```
+```console
 $ bundle
 ```
 
 ## Usage
 
-### Customing Stylesheet
-
-Creare a new file `/assets/css/style.scss` in your Jekyll site.
-
-And then add the following content:
-
-```scss
----
----
-
-@import {{ site.theme }}
-
-// add your style below
-```
-
-### Changing the Number of Tabs
-
-When adding or deleting files in the `_tabs` folder, you need to complete the section [Customing Stylesheet](#customing-stylesheet) first, and then add a new line before `@import`:
-
-```scss
-$tab-count: {{ site.tabs | size | plus: 1 }};
-```
-
-### Publishing to GitHub Pages
-
-See the `jekyll-theme-chirpy`'s [deployment instructions](https://github.com/cotes2020/jekyll-theme-chirpy#deployment). Note that in order to use GitHub Actions caching to speed up the deployment, you should add the `Gemfile.lock` file to your repository.
-
-### Updating
-
-Please note that files and directories in this project may change as the [`jekyll-theme-chirpy`][chirpy] is updated. When updating, please ensure that the file directory structure of your Jekyll site is the same as that of this project.
-
-And then execute:
-
-```console
-$ bundle update jekyll-theme-chirpy
-```
-
