Pages are rendered from the _posts directory and are written in markdown. To add a page, create a file in the _posts directory with the format YEAR-MONTH-DAY-title.md and add the following front-matter:
---
title: Your title
date: 20 May 2019 # Date when the page was last updated
permalink: /newpage # What url you want the page to be shown at (/newpage will show the page at exunclan.github.io/resources/newpage)
layout: post
---
and you're ready to write!
