-# Accessibility
+# Accessiblity
+Using semantic HTML plays a key role when it comes to accessibility.
 
-> TODO: Add content
+## Accessible Rich Internet Applications - ARIA
+WAI-ARIA, the Accessible Rich Internet Applications specification, defines a way to make Web content and Web applications more accessible to people with disabilities. 
+
+> Note: It is [recommended][using-aria] to use semantic elements as the primary method to achieve accessibility rather than adding aria attributes. Adding aria attributes should be seen as a secondary method for creating accessible elements.
+
+### Role
+The `role` attribute describes the role the element plays in the context of the document.
+
+Check the list of WAI-ARIA roles [here][roles]
+
+## Icons
+When using icons or images that aren't absolutely needed to understand the context, we should use `aria-hidden="true"`.
+
+On the other hand, if an icon is crucial to understand the context we should do one of the following:
+1. Use `aria-label` in the element with a meaningful description
+1. Use `aria-labelledby` to point to an element that contains the explanation for that icon
+
+## Form inputs
+In forms we should use the `for` attribute in the label statement:
+```
+<div>
+  <label for="name">Fill in your name:</label>
+  <input type="text" id="name" name="name">
+</div>
+```
+
+## Testing
+
+1. On MacOS you can use [VoiceOver][voice-over] by pressing `cmd+F5`.
+1. On Windows you can use [Narrator][narrator] by pressing Windows logo key + Ctrl + Enter.
