What is Alt Text?
Alt text allow users and editors to provide a text equivalent for the object (like an image, area, or etc). This is a short, text description of the visual contents of the image in context if applicable.

Why is it important?
There are many reasons as to why the inclusion of alt text in images is important to end-users. First, readers with visual impairments of vaing degrees who browse Wikipedia with assistive technology, such as a screen reader or braille display, will not be able to understand what the image is trying to convey. Second, end users that do not load images (such as users of Wikipedia Zero) will not be able to gain any contextual richness from the images as there is no associated alt text to provide the "visual". And lastly, bots will often pull alt tags as a means of deriving context.

How do I do it correctly?
According to the W3C, the governing body of the internet, use text that fulfills the same function as the image. This is because we are attempting to relate the image to the visual information contained in the image. Meaning that we are looking to glean the same information from the alt text that one would get from looking at the image visually.
