-### Prerequisites
+## Installation

-Follow the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of basic environment (`Ruby`, `RubyGems` and `Bundler`). 
+[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork) on GitHub, and clone the fork to local by:

-To improve the writing experience, we need to use some script tools. If your machine is running Debian or macOS, make sure that [GNU coreutils](https://www.gnu.org/software/coreutils/) is installed. Otherwise, install by:
-
-* Debian
-
-```console
-$ sudo apt-get install coreutils
+```terminal
+$ git clone git@github.com:<username>/jekyll-theme-chirpy -b master --single-branch
 ```

-* macOS
+### Setting up the local envrionment

-```console
-$ brew install coreutils
-```
+If you would like to run or build the project on your local machine, please follow the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems` and `Bundler`. 

-
-### Jekyll Plugins
-
-[Fork **Chirpy** from GitHub](https://github.com/cotes2020/jekyll-theme-chirpy/fork), then clone your forked repo to local:
-
-```console
-$ git clone git@github.com:USER/jekyll-theme-chirpy.git -b master
-```
-
-and replace the `USER` above to your GitHub username.
-

+`bundle` will automatically install all the dependencies specified by `Gemfile`.
+
+What's more, in order to generate some extra files (*categories*, *tags* and *last modified list*), we need to use some tool scripts. If your machine is running Debian or macOS, make sure that [GNU coreutils](https://www.gnu.org/software/coreutils/) is installed. Otherwise, install by:
+
+* Debian
+
+  ```console
+  $ sudo apt-get install coreutils
+  ```
+
+* macOS
+
+  ```console
+  $ brew install coreutils
+  ```


 ## Usage

+Running [**Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/) requires some extra files, which cannot be generated by Jekyll native commands, so please strictly follow the methods mentioned below to run or deploy your website.

-### Directory Structure
+### Initialization

-The main files and related brief introductions are listed below.
+Go to the root directory of the project and start initialization:

-```sh
-jekyll-theme-chirpy/
-├── _data
-├── _includes      
-├── _layouts
-├── _posts          # posts stay here
-├── _scripts

+```console
+$ bash tools/init.sh
 ```

+> If you not intend to deploy it on GitHub Pages, append parameter option `--no-gh` at the end of the above command.

-As mentioned above, some files or directories should be removed from your repo:
+What it does is:

- .travis.yml
- .github
+1. Remove some files or directories from your repository:
+    - `.travis.yml`
+    - everything under `.github/`
+    - files under `_posts/`
+    - folder `docs/` 

+2. Unless the option `--no-gh` was enabled, setup the GitHub action workflow by renaming `pages-deploy.yml.hook` of directory `.github/workflows/` to `pages-deploy.yml`.
+
+3. Automatically create a commit to save the changes.

 ### Configuration

 Generally, go to `_config.yml` and configure the variables as needed. Some of them are typical options:
-
 * `url`
-	
-	Set to your website url and there should be no slash symbol at the tail. Format: `<protocol>://<domain>`.
-
-
 * `avatar`
-    
-    It defines the image file location of avatar. The sample image is `/assets/img/sample/avatar.jpg`, and should be replaced by your own one(a square image). Notice that a huge image file will increase the load time of your site, so keep your avatar image size as small as possible(may be *<https://tinypng.com/>* will help).
-
 * `timezone`
-
-    To ensure that the posts' release date matches the city you live in, please modify the field `timezone` correctly. A list of all available values can be found on [TimezoneConverter](http://www.timezoneconverter.com/cgi-bin/findzone/findzone) or [Wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
-
 * `theme_mode`
-  
-	There are three options for the theme color scheme:
-	
-	- **dual** 	- The default color scheme will follow the system settings, but if the system does not support dark mode, or the browser does not support `Media Queries Level 5`, the theme will be displayed as `light` mode by default. Anyway, the bottom left corner of the Sidebar will provide a button for users to switch color schemes.
-
-	- **dark**	- Always show dark mode.
-	- **light**	- Always show light mode.

-###  Deploying to GitHub Pages
+### Deployment

-Before the deployment begins, checkout the file `_config.yml` and make sure that the `url` has been configured. What's more, if you prefer the [Project site on GitHub](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and also use the default domain `<username>.github.io`, remember to change the `baseurl` to your project name that starting with a slash. For example, `/project`.
+Before the deployment begins, checkout the file `_config.yml` and make sure the `url` is configured correctly. Furthermore, if you prefer the [_project site_](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and don't use a custom domain, or you want to visit your website with a base url on a web server other than **GitHub Pages**, remember to change the `baseurl` to your project name that starting with a slash. For example, `/project`.

-#### Option 1: Built by GitHub Pages
+Assuming you have already gone through the [initialization](#initialization), you can now choose any of the following methods to deploy your website.

-By deploying the site in this way, you're allowed to push the source code directly to the remote.

+For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using tool scripts to generate additional page files. Therefore, we can use GitHub Actions to build the site, store the built site files on a new branch, and use that branch as the source of the Pages service.

-**1**. Rename the repository to:
+1. Push any commit to `origin/master` to trigger the GitHub Actions workflow. Once the build is complete, a new remote branch called `gh-pages` will appear, which is used to store the built site files.

-|User or Organization | `<username>.github.io`|
-|Project| Any one except `<username>.github.io`, let's say `project`|

-**2**. Commit the changes of the repo first, then run the publish script:
+3. Choose branch `gh-pages` as your GitHub Pages source.
+
+4. Visit your website at the address indicated by GitHub.
+
+#### Deploy on Other Platforms
+
+On platforms other than GitHub, e.g. GitLab, we cannot enjoy the convenience of **GitHub Actions**. However, we have a tool to make up for this shortcoming.

-#### Finishing work
-
-No matter which way you choose to deploy the website on GitHub, please enforce the `HTTPS` for it. See official docs: [Securing your GitHub Pages site with HTTPS](https://help.github.com/en/github/working-with-github-pages/securing-your-github-pages-site-with-https).

-As mentioned above, some files or directories should be removed from your repo:
+What it does is:

- .travis.yml
- .github
+1. Remove some files or directories from your repository:
+    - `.travis.yml`
+    - everything under `.github/`
+    - files under `_posts/`
+    - folder `docs/` 

+2. Unless the option `--no-gh` was enabled, setup the GitHub action workflow by renaming `pages-deploy.yml.hook` of directory `.github/workflows/` to `pages-deploy.yml`.

-## Configuration
+3. Automatically create a commit to save the changes.
+
+### Configuration

 Generally, go to `_config.yml` and configure the variables as needed. Some of them are typical options:
-
 * `url`
-    
-    Set to your website url and there should be no slash symbol at the tail. Format: `<protocol>://<domain>`.
-
-
 * `avatar`
-    
-    It defines the image file location of avatar. The sample image is `/assets/img/sample/avatar.jpg`, and should be replaced by your own one (a square image). Notice that a huge image file will increase the load time of your site, so keep your avatar image size as small as possible (may be *<https://tinypng.com/>* will help).
-
 * `timezone`
-
-    To ensure that the posts' release date matches the city you live in, please modify the field `timezone` correctly. A list of all available values can be found on [TimezoneConverter](http://www.timezoneconverter.com/cgi-bin/findzone/findzone) or [Wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
-
 * `theme_mode`
-  
-    There are three options for the theme color scheme:
-    
-    - **dual**  - The default color scheme will follow the system settings, but if the system does not support dark mode, or the browser does not support `Media Queries Level 5`, the theme will be displayed as `light` mode by default. Anyway, the bottom left corner of the Sidebar will provide a button for users to switch color schemes.
-
-    - **dark**  - Always show dark mode.
-    - **light** - Always show light mode.

-##  Deploying to GitHub Pages
+### Deployment

-Before the deployment begins, checkout the file `_config.yml` and make sure that the `url` has been configured. What's more, if you prefer the [Project site on GitHub](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and also use the default domain `<username>.github.io`, remember to change the `baseurl` to your project name that starting with a slash. For example, `/project`.
+Before the deployment begins, checkout the file `_config.yml` and make sure the `url` is configured correctly. Furthermore, if you prefer the [_project site_](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and don't use a custom domain, or you want to visit your website with a base url on a web server other than **GitHub Pages**, remember to change the `baseurl` to your project name that starting with a slash. For example, `/project`.

+Assuming you have already gone through the [initialization](#initialization), you can now choose any of the following methods to deploy your website.

-### Option 1: Built by GitHub Pages
+#### Deploy on GitHub Pages

-By deploying the site in this way, you're allowed to push the source code directly to the remote.
+For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using tool scripts to generate additional page files. Therefore, we can use GitHub Actions to build the site, store the built site files on a new branch, and use that branch as the source of the Pages service.

-> **Note**: If you want to use any third-party Jekyll plugins that not in [this list](https://pages.github.com/versions/), stop reading the current approach and go to [*Option 2: Build locally*](#option-2-build-locally).
+1. Push any commit to `origin/master` to trigger the GitHub Actions workflow. Once the build is complete, a new remote branch called `gh-pages` will appear, which is used to store the built site files.

-**1**. Rename the repository to:
+2. Unless you prefer to project sites, rename your repository to `<username>.github.io` on GitHub.

-|Site Type | Repo's Name|
-|:---|:---|
-|User or Organization | `<username>.github.io`|
-|Project| Any one except `<username>.github.io`, let's say `project`|
+3. Choose branch `gh-pages` as your GitHub Pages source.

-**2**. Commit the changes of the repo first, then run the publish script:
+4. Visit your website at the address indicated by GitHub.
+
+#### Deploy on Other Platforms
+
+On platforms other than GitHub, e.g. GitLab, we cannot enjoy the convenience of **GitHub Actions**. However, we have a tool to make up for this shortcoming.

-No matter which way you choose to deploy the website on GitHub, please enforce the `HTTPS` for it. See official docs: [Securing your GitHub Pages site with HTTPS](https://help.github.com/en/github/working-with-github-pages/securing-your-github-pages-site-with-https).

 ## 安装

-### 准备工作
+[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork)，然后克隆到本地：

-按照 [Jekyll 官方文档](https://jekyllrb.com/docs/installation/) 完成基础环境的安装 (`Ruby`，`RubyGem`，`Bundler`)。
-
-为了使用项目内免费提供的脚本工具增进写作体验，如果你的机器系统是 Debian 或者 macOS，则需要确保安装了 [GNU coreutils](https://www.gnu.org/software/coreutils/)。否则，通过以下方式获得：
-
-* Debian
-
- ```console
- $ sudo apt-get install coreutils
- ```
-
-* macOS
-
- ```console
- $ brew install coreutils
- ```
-
-接着，[fork](https://github.com/cotes2020/jekyll-theme-chirpy/fork) 一份代码，然后克隆你 Fork 的仓库到本地机器上。
-
-```console
-$ git clone git@github.com:USER/jekyll-theme-chirpy.git -b master
+```terminal
+$ git clone git@github.com:<username>/jekyll-theme-chirpy -b master --single-branch
 ```

-把上述的`USER` 替换为你的 GitHub username。
+### 设置本地环境
+
+如果你想在本地运行或构建, 参考 [Jekyll Docs](https://jekyllrb.com/docs/installation/)安装 `Ruby`， `RubyGems` 和 `Bundler`。


-### 安装 Jekyll 插件
-
-本地首次运行或编译，请在项目根目录下运行:

+    - `.travis.yml`
+    - `.github` 下的文件和目录
+    - `_posts` 下的文件
+    - `docs` 目录

+2. 配置了 GitHub Actions：把 `.github/workflows/` 的文件 `pages-deploy.yml.hook` 重命名为 `pages-deploy.yml`。

-    定义网站 URL，注意结尾不带 `/`。格式： `<protocol>://<domain>`.
-
 * `avatar`

-    定义头像，示例的文件放置在：`/assets/img/sample/avatar.jpg`. 把它换成你自己的头像，路径不限定，越小越好。(压缩图像体积可上这个网站：*<https://tinypng.com/>* ).
-
 * `timezone`
-
-    定义时区 ，默认为 `亚洲/上海`，如果肉身翻墙要换城市可在此列表找到： [TimezoneConverter](http://www.timezoneconverter.com/cgi-bin/findzone/findzone) 或者 [Wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
-
 * `theme_mode`
-  
-    定义颜色方案，有三种可选：:
-    
-    - **dual**  - 自动跟随系统的 `深色`/`浅色` 设置，当系统或者浏览器不支持深色模式，则默认显示为浅色模式。无论如何，侧边栏左下角都会显示一个颜色切换按钮。
-    - **dark**  - 全程深色模式。
-    - **light** - 全程浅色模式。

-#### 方法 1: 由 GitHub Pages 生成站点
+假设你已经完成了 [初始化](#初始化)，现在你可以选择下列其中一个方式去站点部署。

-依照本方法，你可以直接把源码推送到远端仓库。
+#### 部署到 GitHub Pages

-> **注**: 如果你想使用任何不在这个[列表](https://pages.github.com/versions/)上的插件，越过此方法，直接看 [*方法 2: 本地构建*](#方法-2-本地构建).
+由于安全原因，GitHub Pages 的构建强制加了 `safe`参数，这导致了我们不能使用脚本工具去创建所需的附加页面。因此，我们可以使用 GitHub Actions 去构建站点，把站点文件存储在一个新分支上，再指定该分支作为 Pages 服务的源。

-**1**. 仓库改名为:
+1. 推送任意一个 commit 到 `origin/master` 以触发 GitHub Actions workflow。一旦 build 完毕，远端将会自动出现一个新分支 `gh-pages` 用来存储构建的站点文件。

-|站点类型 | 仓库名称|
-|:---|:---|
-|User or Organization | `<username>.github.io`|
-|Project| `<username>.github.io` 以外的名字，譬如 `project`|
+2. 除非你是使用 project 站点, 否则重命名你的仓库为 `<username>.github.io`。

-**2**. 提交本地更改，然后运行:
+3. 选择分支 `gh-pages` 作为 GitHub Pages 的源.
+
+4. 按照 GitHub 指示的地址去访问你的网站。
+
+#### 部署到其他 Pages 平台
+
+在 GitHub 之外的平台，例如 GitLab，就没法享受 **GitHub Actions** 的便利了。不过先别慌，可以通过工具来弥补这个遗憾。

-
-
-#### 方法 2: 本地构建
-
-由于安全原因，GitHub Pages 不允许第三方插件运行，如果你想突破规则，就要本地构建站点内容。
-
-**1**. 到 GitHub 网页，创建一个新的仓库，根据以下规则命名: 
-
-|站点类型 | 仓库名称|

-|User or Organization | `<username>.github.io`|
-|Project| `<username>.github.io` 以外的名字， 例如 `project`|
