-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.
+The startup template for [**Jekyll Theme Chirpy**][chirpy].
 
-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.
+When installing the **Chirpy** theme 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. (You can find the gem files by using the command `bundle info --path jekyll-theme-chirpy`). To fully use all the features of **Chirpy**, you need to copy the other critical files/directories from the theme's gem to your Jekyll site.
 
-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:
+The critical files/directories to run or build the **Chirpy** theme are as follows:
 
 ```shell
 .
-├── _config.yml
+├── _data
 ├── _plugins
 ├── _tabs
-└── index.html
+├── _config.yml
+└──  index.html
 ```
 
-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.
+So we've extracted all the **Chirpy** gem necessary content here to help you get started quickly.
+
+## Installation
+
+[Use this template][usetemplate] to generate a new repository, and then execute:
+
+[usetemplate]: https://github.com/cotes2020/chirpy-starter/generate
+
+```
+$ bundle
+```
 
 ## Usage
 
-Check out the [theme's docs](https://github.com/cotes2020/jekyll-theme-chirpy/wiki).
+### Customing Stylesheet
 
-## Contributing
+Creare a new file `/assets/css/style.scss` in your Jekyll site.
 
-This repository is automatically updated with new releases from the theme repository. If you encounter any issues or want to contribute to its improvement, please visit the [theme repository][chirpy] to provide feedback.
+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
+$tab-count: {{ site.tabs | size | plus: 1 }};
+```
+
+### Publishing to GitHub Pages
+
+See the [deployment instructions](https://github.com/cotes2020/jekyll-theme-chirpy#deployment) of `jekyll-theme-chirpy`.
+
+### Upgrading
+
+First, please modify the target version number of `jekyll-theme-chirpy` in the `Gemfile` (e.g., `gem "jekyll-theme-chirpy", "~> 4.0", ">= 4.0.1"`). In addition, if the major version number is updated, you need to update the critical files to keep them the same as this project.
+
+After that, execute the following command:
+
+```console
+$ bundle update jekyll-theme-chirpy
+```
+
