-Apache Submarine site
+# Apache Submarine website
+
+This readme will walk you through building the Submarine website
+
+## Introduction
+
+1. The `master` branch of the submarine is used to manage the website source code. Every time you modify the website, you need to submit it to the `master` branch for saving.
+
+2. The `asf-site` branch is used for the static page branch of the website. Every time you modify the website, you need to save the latest generated static page here. https://submarine.apache.org will be updated automatically.
+
+## Build website by docker
+
+```
+git clone https://github.com/apache/submarine-site.git
+git checkout master
+
+docker run -it -p 4000:4000 -v $PWD/submarine-site:/submarine-site hadoopsubmarine/submarine-website:1.0.0 bash
+cd /submarine-site
+bundle exec jekyll serve --watch --host=0.0.0.0
+```
+
+The static page of the website will be generated in the `$PWD/submarine-site/_site` directory.
+
+view submarine website in local: http://localhost:4000/
+
+## Adding a new page
+
+```
+rake page name="new-page.md"
+```
+
+## Deploy website
+
+1. Submit the `master` branch to github repo.
+2. Copy the `_site` directory to the other backup path, e.g., `back_site`.
+3. Switch to the `asf-site` branch, clear all the contents of the directory, copy the contents of the `back_site` directory to the root directory, and submit the `asf-site` branch to github repo.
