## Blog
Adding a new blog post is a four-step process.
> Some posts have a `permalink` and `comments` in the blog post YAML header. You will not need these for new blog posts. These are an artifact of migrating the blog from Wordpress to gh-pages.
1. Create your blog post in `./_posts` in markdown (file extension `.md` or `.markdown`). See current posts in that folder or `2016-04-07-blog-post-example.md` for an example of the YAML format.
- You can add a `<!--truncate-->` tag in the middle of your post such that you show only the excerpt above that tag in the main `/blog` index on your page.
1. If you have not authored a blog post before, modify the `./_data/authors.yml` file with the `author` id you used in your blog post, along with your full name and Facebook ID to get your profile picture.
1. [Run the site locally](./README.md) to test your changes. It will be at `http://127.0.0.1/blog/your-new-blog-post-title.html`
1. Push your changes to GitHub.
