Collections like posts and pages work as you'd expect. If you're new to them be sure to read [Jekyll's documentation](https://jekyllrb.com/docs/collections/).
Minimal Mistakes has been built with collections in mind and you will find [several examples]({{ base_path }}/collection-archive/) on the demo site ([portfolio]({{ base_path }}/portfolio/), [recipes]({{ base_path }}/recipes/), pets).
**Collections in the Wild:** This set of documentation is also [built as a collection]({{ site.gh_repo }}/gh-pages/_docs/) if you're looking for a fully fleshed out example with custom sidebar navigation, next/previous pagination, and more.
A popular use case for collections is to build a portfolio section as part of a personal site. Let's quickly walk through the steps to do that.
**Step 1:** Configure the portfolio collection by adding the following to `_config.yml`.
```yaml
collections:
portfolio:
output: true
permalink: /:collection/:path/
```
These settings essentially say output `index.html` files for each portfolio document in `_portfolio` at `_site/portfolio/<document-filename>/`.
Just like posts and pages you'll probably want to set some defaults for the Front Matter:
```yaml
defaults:
# _portfolio
- scope:
path: ""
type: portfolio
values:
layout: single
author_profile: false
share: true
```
And then create portfolio content like [`_portfolio/foo-bar-website.md`]({{ site.gh_repo }}/gh-pages/_portfolio/foo-bar-website.md), to end up with something like this.
