+### Social Follow + Share
+
+The theme automatically adds "Follow" link icons to the header and footer and "Share" link icons to pages unless `disable_share` site parameter is set to true. Each built-in services sports a label, an icon and a color.
+
+In order to register a service to be used, user must add an `ananke_socials` parameter to its project configuration file and list them through it in the desired order. Each entry must bear a 
+- name*: It matches the built-in service reference (Ex: twitter, github)
+- url*: The url of the handle's profile on the service (Ex: https://twitter.com/theNewDynamic, https://github.com/
+theNewDynamic)
+
+```yaml
+params:
+  ananke_socials:
+  - name: twitter
+    url: https://twitter.com/theNewDynamic
+  - name: github
+    url: https://github.com/theNewDynamic
+```
+
+If user needs to overwrite default `color` and `label` of the service, they simply need to append the following to the entry:
+- label: The displayed name of the service to be used to popuplate `[title]` attributes and read-only. (Ex: Twitter, GitHub)
+- color: Used for styling purposes. (Ex: '#1da1f2', '#6cc644')
+
+```yaml
+params:
+  ananke_socials:
+  - name: twitter
+    url: https://twitter.com/theNewDynamic
+    label: TND Twitter
+  - name: github
+    url: https://github.com/theNewDynamic
+    label: TND GitHub Account
+    color: '#ff6800'
+```
+
+#### Social Icons Customization
+
+On top of easily customizing the built-in services' label and color, user can overwrite their icon by adding an svg file at `/assets/ananke/socials` with a filename matching the service's name.
+For example, in order to use your own GitHub icon, simply add an svg file at `/assets/ananke/socials/github.svg`
+
+#### Built-in Services
+Here is the list of built-in services. Those marked with an `*` are also part of the "Share" module.
+
+- twitter*
+- instagram
+- youtube
+- github
+- gitlab
+- keybase
+- linkedin*
+- medium
+- mastodon
+- slack
+- stackoverflow
+- facebook*
+- rss
+
+#### Complement
+
+In order to add an unkown service (absent from the list above), you simply need to add all three settings to `ananke_socials`: name, url, label, color, and optionally add an icon file matching the `name` to the `assets/ananke/socials` directory. In the absence of an icon, the theme will print the service's label.
+
 ### Update font or body classes
 
 The theme is set, by default, to use a near-white background color and the "Avenir" or serif typeface. You can change these in your config file with the `body_classes` parameter, like this:

assets/ananke/css/_social-icons.css
