 - It would be helpful to understand what Markdown is and how to write it. Markdown is just a way to take a piece of text and format it to look a little nicer.  For example, this whole instruction set that you're reading is written in markdown - it's just text with some words being bold/larger/italicized/etc. I recommend taking 5 minutes to learn markdown [with this amazingly easy yet useful tutorial](http://markdowntutorial.com/).

 Disclaimer: I personally am NOT using local development so I don't know much about running Jekyll locally. If you follow this route, please don't ask me questions because unfortunately I honestly won't be able to help!
 
-Aditionally, if you choose to deploy Jekyll using a local ruby installation, you can tell Jekyll to automatically categorize your blog posts by tags. You just need to set `link-tags: true` in `_config.yml`. Jekyll will then generate a new page for each unique tag which lists all of the posts that belong to that tag.

 ## FAQ
 
 Beautiful Jekyll is actively used by thousands of people with wildly varying degrees of competency, so it's impossible to answer all the questions that may arise. Below are answers to a few very common questions. Most questions that I get asked are not directly related to this theme, and instead are more general questions about Jekyll or web development. Many such questions can be answered by reading the [Jekyll documentation](http://jekyllrb.com/) or simply by Googling.
