+## Prerequisites

-  </p>
-</details>
+Follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of `Ruby`, `RubyGems`, `Jekyll` and `Bundler`.
+
+## Installation
+
+### Creating a New Site
+
+There are two ways to create a new repository for this theme:
+
+- **[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.
+
+#### Option 1. Using the Chirpy Starter
+
+Create a new repository from the [**Chirpy Starter**][use-starter] and name it `<GH_USERNAME>.github.io`, where `GH_USERNAME` represents your GitHub username.
+
+#### Option 2. Forking on GitHub
+
+[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](https://github.com/cotes2020/jekyll-theme-chirpy/tags) and start writing.
+
+And then execute:
+
+```console
+$ bash tools/init.sh
+```
+
+> **Note**: If you don't want to deploy your site on GitHub Pages, append option `--no-gh` at the end of the above command.
+
+The above command will:
+
+1. Removes some files or directories from your repository:
+    - `.travis.yml`
+    - files under `_posts`
+    - folder `docs`
+
+2. If the option `--no-gh` is provided, 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. Removes item `Gemfile.lock` from `.gitignore`.
+
+4. Creates a new commit to save the changes automatically.
+
+### Installing Dependencies
+
+Before running for the first time, go the root directory of your site, and install dependencies as follows:
+
+```console
+$ bundle
+```
+
+## Usage
+
+### Configuration
+
+Update the variables of `_config.yml` as needed. Some of them are typical options:
+
+- `url`
+- `avatar`
+- `timezone`
+- `lang`
+
+### Customing Stylesheet
+
+If you need to customize stylesheet, copy the theme's `assets/css/style.scss` to the same path on your Jekyll site, and then add the custom style at the end of the style file.
+
+Starting from [`v4.1.0`][chirpy-4.1.0], if you want to overwrite the SASS variables defined in `_sass/addon/variables.scss`, create a new file `_sass/variables-hook.scss` and assign new values to the target variable in it.
+
+### 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 the site on Docker with the following command:
+
+```console
+$ docker run -it --rm \
+    --volume="$PWD:/srv/jekyll" \
+    -p 4000:4000 jekyll/jekyll \
+    jekyll serve
+```
+
+After a while, the local service will be published at _<http://127.0.0.1:4000>_.
+
+### 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 by Using Github Actions
+
+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.
+
+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 [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/deploy.sh`. Otherwise, copy it from here to your Jekyll site.
+
+- Furthermore, if you have committed `Gemfile.lock` to the repo, and your runtime system is not Linux, don't forget to update the platform list in the lockfile:
+
+  ```console
+  $ bundle lock --add-platform x86_64-linux
+  ```
+
+After the above steps, 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.
+
+    ![gh-pages-sources](https://cdn.jsdelivr.net/gh/cotes2020/chirpy-images@0a003683c0c3ca549d12c309f9b3e03ea20981e5/posts/20190809/gh-pages-sources.png)
+
+3. Visit your website at the address indicated by GitHub.
+
+#### Manually Build and Deploy
+
+On self-hosted servers, you cannot enjoy the convenience of **GitHub Actions**. Therefore, you should build the site on your local machine and then upload the site files to the server.
+
+Go to the root of the source project, and build your site as follows:
+
+```console
+$ JEKYLL_ENV=production bundle exec jekyll b
+```
+
+Or build the site on Docker:
+
+```console
+$ 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 the target server.
+
+### 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`), editing the `Gemfile` and update the version number of the them gem, for example:
+    ```diff
+    - gem "jekyll-theme-chirpy", "~> 3.2", ">= 3.2.1"
+    + gem "jekyll-theme-chirpy", "~> 3.3", ">= 3.3.0"
+    ```
+
+    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` 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.
