 # How to Contribute
 
-We'd like to thank you for sparing time to improve this project! Here are some guidelines for contributing：
+I want to thank you for sparing a time to improve this project! Here are some guidelines for contributing：
 
-To ensure that the blog design is not confused, this project does not accept suggestions for design changes, such as color scheme, fonts, typography, etc. If your request is about an enhancement, it is recommended to first submit a [_Feature Request_](https://github.com/cotes2020/jekyll-theme-chirpy/issues/new?labels=enhancement&template=feature_request.md) issue to discuss whether your idea fits the project.
-
-## Basic Process
+To ensure that the blog design is not confused, this project does not accept suggestions for design changes, such as color scheme, fonts, typography, etc. If your request is about an enhancement, it is recommended to first submit a [`Feature Request`](https://github.com/cotes2020/jekyll-theme-chirpy/issues/new?labels=enhancement&template=feature_request.md) issue to discuss whether your idea fits the project. 
 
 Generally, contribute to the project by:
 
 1. Fork this project on GitHub and clone it locally.
-2. Create a new branch from the default branch and give it a descriptive name (format: `feature/<add-new-feat>` / `fix/<fix-a-bug>`).
-3. After completing the development, submit a new _Pull Request_. Note that the commit message must follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/), otherwise it will fail the PR check.
-
-## Modifying JavaScript
-
-If your contribution involves JavaScript modification, please read the following sections.
-
-### Inline Scripts
-
-If you need to add comments to the inline JavaScript (the code between the HTML tags `<script>` and `</script>`), please use `/* */` instead of two slashes `//`. Because the HTML will be compressed by [jekyll-compress-html](https://github.com/penibelst/jekyll-compress-html) during deployment, but it cannot handle the `//` properly, which will disrupt the structure of the compressed HTML.
-
-### External Scripts
-
-If you need to add/change/delete the JavaScript in the directory `_javascript/`, setting up [`Node.js`](https://nodejs.org/) and [`npx`](https://www.npmjs.com/package/npx) is a requirement. And then install the development dependencies:
-
-```console
-$ npm i
-```
-
-During JavaScript development, real-time debugging can be performed through the following commands:
-
-Firstly, start a Jekyll server:
-
-```console
-$ bash tools/run.sh
-```
-
-And then open a new terminal tab and run:
-
-```console
-# Type 'Ctrl + C' to stop
-$ npx gulp dev
-```
-
-After debugging, run the command `npx gulp` (without any argument) will automatically output the compressed files to the directory `assets/js/dist/`.
-
-## Verify the commit messages
-
-If you want to make sure your commits pass the CI check, you can refer to the following steps.
-
-Install `commitlint` & `husky`:
-
-```console
-$ npm i -g @commitlint/{cli,config-conventional} husky
-```
-
-And then enable `husky`:
-
-```console
-$ husky install
-```
+2. Create a new branch from `master` and give it a descriptive name (e.g., `my-new-feature`, `fix-a-bug`).
+3. After completing the development, commit and push to remote.
+4. Submit a new pull request.

+## Prerequisites
 
-## Quick Start
+Follow the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems`, `Jekyll` and `Bundler`.
 
-Before starting, please follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems`, `Jekyll`, and `Bundler`. In addition, [Git](https://git-scm.com/) is also required to be installed.
+## Installation
 
-### Step 1. Creating a New Site
+There are two ways to get the theme:
 
-Create a new repository from the [**Chirpy Starter**](https://github.com/cotes2020/chirpy-starter/generate) and name it `<GH_USERNAME>.github.io`, where `GH_USERNAME` represents your GitHub username.
+- **Install from RubyGems** - Easy to update, isolate irrelevant project files so you can focus on writing.
+- **Fork on GitHub** - Convenient for custom development, but difficult to update, only suitable for web developers.
 
-### Step 2. Installing Dependencies
+### Installing the Theme Gem
 
-Before running for the first time, go to the root directory of your site, and install dependencies as follows:
+Add this line to your Jekyll site's `Gemfile`:
+
+```ruby
+gem "jekyll-theme-chirpy"
+```
+
+And add this line to your Jekyll site's `_config.yml`:
+
+```yaml
+theme: jekyll-theme-chirpy
+```
+
+And then execute:
 
 ```console
 $ bundle
 ```
 
-### Step 3. Running Local Server
+Finally, copy the required files from the theme's gem (for detailed files, see [starter project][starter]) to your Jekyll site.
 
-Run the following command in the root directory of the site:
+> **Hint**: To locate the installed theme’s gem, execute:
+>
+> ```console
+> $ bundle info --path jekyll-theme-chirpy
+> ```
+
+Or you can [**use the starter template**][use-starter] to create a Jekyll site to save time copying files from the theme's gem. We have prepared everything for you there!
+
+### Fork on GitHub
+
+[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork) on GitHub and then clone your fork to local. (Please note that the default branch code is in development.  If you want the blog to be stable, please switch to the [latest tag](https://github.com/cotes2020/jekyll-theme-chirpy/tags) and start writing.)
+
+Install gem dependencies by:
+
+```console
+$ bundle
+```
+
+And then execute:
+
+```console
+$ bash tools/init.sh
+```
+
+> **Note**: If you don't plan to deploy your site on GitHub Pages, append parameter option `--no-gh` at the end of the above command.
+
+What it does is:
+
+1. Remove some files or directories from your repository:
+    - `.travis.yml`
+    - files under `_posts`
+    - folder `docs`
+
+2. If you use the `--no-gh` option, the directory `.github` will be deleted. Otherwise, setup the GitHub Action workflow by removing the extension `.hook` of `.github/workflows/pages-deploy.yml.hook`, and then remove the other files and directories in the folder `.github`.
+
+3. Automatically create a commit to save the changes.
+
+## Usage
+
+### Configuration
+
+Update the variables of `_config.yml` as needed. Some of them are typical options:
+
+- `url`
+- `avatar`
+- `timezone`
+- `lang`
+
+### Running Local Server
+
+You may want to preview the site contents before publishing, so just run it by:
 
 ```console
 $ bundle exec jekyll s
 ```
 
-Or run with Docker:
+Or run the site on Docker with the following command:
 
-```console
+```terminal
 $ docker run -it --rm \
     --volume="$PWD:/srv/jekyll" \
     -p 4000:4000 jekyll/jekyll \
     jekyll serve
 ```
 
-After a while, navigate to the site at <http://localhost:4000>.
+Open a browser and visit to _<http://localhost:4000>_.
+
+### Deployment
+
+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, e.g, `/project-name`.
+
+Now you can choose ONE of the following methods to deploy your Jekyll site.
+
+#### Deploy on GitHub Pages
+
+For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using plugins 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 GH Pages service.
+
+Quickly check the files needed for GitHub Actions build:
+
+- Ensure your Jekyll site has the file `.github/workflows/pages-deploy.yml`. Otherwise, create a new one and fill in the contents of the [workflow file][workflow], and the value of the `on.push.branches` should be the same as your repo's default branch name.
+- Ensure your Jekyll site has file `tools/test.sh` and `tools/deploy.sh`. Otherwise, copy them from this repo to your Jekyll site.
+
+And then rename your repository to `<GH-USERNAME>.github.io` on GitHub.
+
+Now publish your Jekyll site by:
+
+1. Push any commit to remote to trigger the GitHub Actions workflow. Once the build is complete and successful, a new remote branch named `gh-pages` will appear to store the built site files.
+
+2. Browse to your repo's landing page on GitHub and select the branch `gh-pages` as the [publishing source](https://docs.github.com/en/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site) through _Settings_ → _Options_ → _GitHub Pages_:
+
+    ![gh-pages-sources](https://cdn.jsdelivr.net/gh/cotes2020/chirpy-images/posts/20190809/gh-pages-sources.png)
+
+3. Visit your website at the address indicated by GitHub.
+
+#### Deploy on Other Platforms
+
+On platforms other than GitHub, we cannot enjoy the convenience of **GitHub Actions**. Therefore, we should build the site locally (or on some other 3rd-party CI platform) and then put the site files on the server.
+
+Go to the root of the source project, build your site by:
+
+```console
+$ JEKYLL_ENV=production bundle exec jekyll b
+```
+
+Or build the site with Docker by:
+
+```terminal
+$ docker run -it --rm \
+    --env JEKYLL_ENV=production \
+    --volume="$PWD:/srv/jekyll" \
+    jekyll/jekyll \
+    jekyll build
+```
+
+Unless you specified the output path, the generated site files will be placed in folder `_site` of the project's root directory. Now you should upload those files to your web server.

-### Author Information
-
-The author information of the post usually does not need to be filled in the _Front Matter_ , they will be obtained from variables `social.name` and the first entry of `social.links` of the configuration file by default. But you can also override it as follows:
-
-Add author information in `_data/authors.yml` (If your website doesn't have this file, don't hesitate to create one.)
-
-```yaml
-<author_id>:
-  name: <full name>
-  twitter: <twitter_of_author>
-  url: <homepage_of_author>

-{: file="_data/authors.yml" }
-
-And then set up the custom author in the post's YAML block:
-
-```yaml
----
-author: <author_id>

-```
-
-> Another benefit of reading the author information from the file `_data/authors.yml`{: .filepath } is that the page will have the meta tag `twitter:creator`, which enriches the [Twitter Cards](https://developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started#card-and-content-attribution) and is good for SEO.

-### Image Path
-
-When a post contains many images, it will be a time-consuming task to repeatedly define the path of the images. To solve this, we can define this path in the YAML block of the post:

-```yml

-  alt: image alternative text

-
-Except for `alt`, all other options are necessary, especially the `width` and `height`, which are related to user experience and web page loading performance. The above section "[Size](#size)" also mentions this.
-
-Starting from _Chirpy v5.0.0_, the attributes `height` and `width` can be abbreviated: `height` → `h`, `width` → `w`. In addition, the [`img_path`](#image-path) can also be passed to the preview image, that is, when it has been set, the  attribute `path` only needs the image file name.

-There are two ways to create a new repository for this theme:
+- **Install from RubyGems** - Easy to update, isolate irrelevant project files so you can focus on writing.
+- **Fork on GitHub** - Convenient for custom development, but difficult to update, only suitable for web developers.
 
-- [**Using the Chirpy Starter**](#option-1-using-the-chirpy-starter) - Easy to upgrade, isolates irrelevant project files so you can focus on writing.
-- [**Forking on GitHub**](#option-2-forking-on-github) - Convenient for custom development, but difficult to upgrade. Unless you are familiar with Jekyll and are determined to tweak or contribute to this project, this approach is not recommended.
+### Installing the Theme Gem
 
-#### Option 1. Using the Chirpy Starter
+Add this line to your Jekyll site's `Gemfile`:
 
-Create a new repository from the [**Chirpy Starter**][use-starter] and name it `<GH_USERNAME>.github.io`, where `GH_USERNAME` represents your GitHub username.
+```ruby
+gem "jekyll-theme-chirpy"
+```
 
-#### Option 2. Forking on GitHub
+And add this line to your Jekyll site's `_config.yml`:
 
-[Fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork) on GitHub and rename it to `<GH_USERNAME>.github.io`. Please note that the default branch code is in development.  If you want the site to be stable, please switch to the [latest tag][latest-tag] and start writing.
+```yaml
+theme: jekyll-theme-chirpy
+```
+
+And then execute:
+
+```console
+$ bundle
+```
+
+Finally, copy the required files from the theme's gem (for detailed files, see [starter project][starter]) to your Jekyll site.
+
+> **Hint**: To locate the installed theme’s gem, execute:
+>
+> ```console
+> $ bundle info --path jekyll-theme-chirpy
+> ```
+
+Or you can [**use the starter template**][use-starter] to create a Jekyll site to save time copying files from the theme's gem. We have prepared everything for you there!

 Now you can choose ONE of the following methods to deploy your Jekyll site.
 
-### Deploy by Using Github Actions
+#### Deploy on GitHub Pages
 
-For security reasons, GitHub Pages build runs on `safe` mode, which restricts us from using plugins 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 GitHub Pages service.

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 GH Pages service.
 
 Quickly check the files needed for GitHub Actions build:
 
-- Ensure your Jekyll site has the file `.github/workflows/pages-deploy.yml`{: .filepath}. Otherwise, create a new one and fill in the contents of the [sample file][workflow], and the value of the `on.push.branches` should be the same as your repo's default branch name.

+- Ensure your Jekyll site has file `tools/test.sh` and `tools/deploy.sh`. Otherwise, copy them from this repo to your Jekyll site.
 
-- Ensure your Jekyll site has file `tools/deploy.sh`{: .filepath}. Otherwise, copy it from here to your Jekyll site.
-
-- Furthermore, if you have committed `Gemfile.lock`{: .filepath} to the repo, and your runtime system is not Linux, don't forget to update the platform list in the lock file:
-
-  ```console
-  $ bundle lock --add-platform x86_64-linux
-  ```
-
-After the above steps, rename your repository to `<GH_USERNAME>.github.io` on GitHub.
+And then rename your repository to `<GH-USERNAME>.github.io` on GitHub.
 
 Now publish your Jekyll site by:
 
 1. Push any commit to remote to trigger the GitHub Actions workflow. Once the build is complete and successful, a new remote branch named `gh-pages` will appear to store the built site files.
 
-2. Browse to your repository on GitHub. Select the tab _Settings_, then click _Pages_ in the left navigation bar, and then in the section **Source** of _GitHub Pages_, select the `/(root)` directory of branch `gh-pages` as the [publishing source][pages-src]. Remember to click <kbd>Save</kbd> before leaving.
+2. Browse to your repo's landing page on GitHub and select the branch `gh-pages` as the [publishing source](https://docs.github.com/en/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site) through _Settings_ → _Options_ → _GitHub Pages_:

 3. Visit your website at the address indicated by GitHub.
 
-### Manually Build and Deploy

-## Upgrading
-
-It depends on how you use the theme:
-
-- If you are using the theme gem (there will be `gem "jekyll-theme-chirpy"` in the `Gemfile`{: .filepath}), editing the `Gemfile`{: .filepath} and update the version number of the theme gem, for example:
-
-  ```diff
-  - gem "jekyll-theme-chirpy", "~> 3.2", ">= 3.2.1"
-  + gem "jekyll-theme-chirpy", "~> 3.3", ">= 3.3.0"
-  ```
-  {: .nolineno file="Gemfile" }
-
-  And then execute the following command:
-
-  ```console
-  $ bundle update jekyll-theme-chirpy
-  ```
-
-  As the version upgrades, the critical files (for details, see the [Startup Template][starter]) and configuration options will change. Please refer to the [Upgrade Guide](https://github.com/cotes2020/jekyll-theme-chirpy/wiki/Upgrade-Guide) to keep your repo's files in sync with the latest version of the theme.
-
-- If you forked from the source project (there will be `gemspec` in the `Gemfile`{: .filepath} of your site), then merge the [latest upstream tags][latest-tag] into your Jekyll site to complete the upgrade.
-The merge is likely to conflict with your local modifications. Please be patient and careful to resolve these conflicts.
