Follow the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installtion of basic environment (Ruby, RubyGem, Bundler and Jekyll).

> **Note**: If you want to add any third-party Jekyll plugins or custom scripts to your project, please refer to [*Option 2: Build locally*](#option-2-build-locally).
**1**. Rename your repository as `<username>.github.io`.
**2**. Commit the changes of your repository, then run the initialization script:
For security reasons, GitHub Pages runs on `safe` mode, which means the third-party Jekyll plugins or custom scripts will not work. If you want to use any another third-party Jekyll plugins, **your have to build locally rather than on GitHub Pages**.
The build results will be stored in the root directory of `<username>.github.io` and don't forget to push the changes of `<username>.github.io` to branch `master` on GitHub.
