How to add a Collection

1. Create a folder called _things, remember you must put an underscore _ before the name

2. Edit the _config.yml to add the following lines under the collections field, the collection name must match the folder name except the underscore

    collections:
      # ... omitting previous collections ...
      things:
        permalink: ":/collection/:path/"
        output: true
   

3. And find the line just_the_docs, add the collection you just defined

    just_the_docs:
      collections:
      # ... omitting previosus collections ...
        things:
          name: "Things"
   

4. And create a single page or page with child in the folder, here I just moved the animals folder we created in the last article inside the _things

Here we go

Some notes:

1. You can change the order of the collection by rearranging the order inside the just_the_docs -> collections.
2. Remember to match the names defined in collections and just_the_docs -> collections.
3. After you add a collection, run bundle exec jekyll serve again to see the effects.
