+## Fork
+
+This is a fork of the Hyde theme I (Brendan Abolivier) made containing a few changes I made:
+
+* Getting rid of Google Fonts
+* Adding FontAwesome
+* Adding meta tags for social network sharing and kind of SEO
+* Adding an `author` key in the `params` section from the configuration file
+* Adding special links to the sidebar menu using values from the `params` section in the configuration file:
+
+| Configuration key | Description                                                       | Example value                                     |
+|-------------------|-------------------------------------------------------------------|---------------------------------------------------|
+| twitter           | Twitter @username                                                 | BrenAbolivier                                     |
+| github            | GitHub username                                                   | babolivier                                        |
+| email             | Email address                                                     | hello@brendanabolivier.com                        |
+| pgp               | PGP key fingerprint                                               | E1D4 B745 7A82 9D77 1FBA 8CAC E860 1572 74A2 8D7E |
+| keyserver         | The key server to use in the key's menu link (must support HTTPS) | pgp.key-server.io                                 |
+| creativeCommons   | The Creative Commons license                                      | by-sa                                             |
+
+* Replacing the `copyright` key in the `params` section from the configuration file with a `creativeCommons` key, expected to be a Creative Commons license identifier (such as `by`, `by-sa`, etc.)
+* Adding a proper RSS feed template including items' descriptions in `<description>` tags, and their contents in `<content:encoded>` tags
+* Adding support for posts' thumbnails, by supporting a `thumbnail` key in a post's front matter. Note that this value must not contain the `https://myblog.tld/images` part of the image's URL, which is added automatically before the key's value.
+
+Note that none of the configuration parameters I added are optional (mainly because I don't need them to be, but PRs are welcome!). A live demo is available [on my blog](https://brendan.abolivier.bzh).
+
+Of course, everything I didn't mess with belongs to the Hugo Hyde theme's authors and contributor.
