 ## Creating new blog posts
 
-To create a new blog post, you can add a new Markdown file in the [\_posts](_posts/) directory. The [name of the file must follow](https://jekyllrb.com/docs/posts/#creating-posts) the format `YYYY-MM-DD-title.md`. The easiest way to do this is to copy an existing blog post and modify it. Note that some blog posts have optional fields in the [frontmatter](https://jekyllrb.com/docs/front-matter/) that are used to enable specific behaviors or functions.

 ## Adding Collections
 
-This Jekyll theme implements `collections` to let you break up your work into categories. The theme comes with two default collections: `news` and `projects`. Items from the `news` collection are automatically displayed on the home page. Items from the `projects` collection are displayed on a responsive grid on projects page.
+This Jekyll theme implements [collections](https://jekyllrb.com/docs/collections/) to let you break up your work into categories. The theme comes with three default collections: `news`, `projects`, and `books`. Items from the `news` collection are automatically displayed on the home page, while items from the `projects` collection are displayed on a responsive grid on projects page and items from the `books` collection are displayed on its own `bookshelf` page inside `submenus`.
 
 You can easily create your own collections, apps, short stories, courses, or whatever your creative work is. To do this, edit the collections in the [\_config.yml](_config.yml) file, create a corresponding folder, and create a landing page for your collection, similar to [\_pages/projects.md](_pages/projects.md).
 
+If you wish to create a collection with support for categories and tags, like the blog posts, you just need to add this collection to the `jekyll-archives` section of your [\_config.yml](_config.yml) file. You can check how this is done with the `books` collection. For more information about customizing the archives section or creating your own archives page, check the [jekyll-archives-v2 documentation](https://george-gca.github.io/jekyll-archives-v2/).

+To access the collections, you can use the `site.COLLECTION_NAME` variable in your templates.

 ## Adding a new publication
 
 To add publications create a new entry in the [\_bibliography/papers.bib](_bibliography/papers.bib) file. You can find the BibTeX entry of a publication in Google Scholar by clicking on the quotation marks below the publication title, then clicking on "BibTeX", or also in the conference page itself. By default, the publications will be sorted by year and the most recent will be displayed first. You can change this behavior and more in the `Jekyll Scholar` section in [\_config.yml](_config.yml) file.
