Congratulations! You now have a blog up and running (or on your way)

Let’s take a pause to take a look at Jekyll’s conventions.

Project Structure

Quiz: Where can you tell Jekyll to ignore specific files?
Hint:* We worked with this file in step 2
_config.yml

File Types

Content and Data

Pages .html, .md root content
Posts .html, .md _posts built-in content type
Data .yml, .csv, .json _data Properties, Configuration, Lists
Collections .html, .md custom Custom content types and data

Theme and Style

Layouts .html _layouts content containers, structural view
Includes .html _includes reusable fragments across layouts or pages
Styles .sass _sass source files for CSS
Assets images, video, pdf … any Jekyll happily serves any file type

Variables

Template Variables Have Scopes

page File’s Front Matter
site Everything in _config.yml
layout Layout file’s front matter
include Include’s front matter OR provided at point of include
data _data collection files (yml, json, csv)
Puzzle: What if you have a property in both a layout AND a page?

They don't conflict. Each variable scope is a separate namespace.
page.blah != layout.blah != site.blah
