+== How to use icons in the wiki
+
+You can use any font awesome icon listed at link:https://fontawesome.com/v4.7.0/icons/[https://fontawesome.com/v4.7.0/icons/] in your wiki documents by use of the icon macro.
+
+.Syntax for inserting icons
+```
+icon:thumbs-up []
+icon:database[role=green] // change color by use of the role syntax
+icon:heart[2x] // icons can be sized
+icon:shield[rotate=90, flip=vertical] // rotate and flip
+```
+
+[TIP]
+====
+When setting the icons name, you do not have to preface it with `fa-`, asciidoctor will accept the font name.
+====
+
+The icon macro has three attributes you can set, they are size, rotate, and flip.
+
+* size +
+  ** The first positional attribute found, scales the icon; values are: `1x` (default), `2x`, `3x`, `4x`, `5x`, `lg`, `fw`
+  ** You can fix the width of the icon by use of the `fw` attribute. This helps when trying to align with other elements by giving the icon a fixed width.
+* rotate
+  ** Rotates the icon; values are: `90`, `180`, `270`
+* flip
+  ** Flips the icon; values are: `horizontal`, `vertical`
+
+The first unnamed attribute is assumed to be the size. For instance, to make the icon twice the size as the default, simply add 2x inside the square brackets.
+
+```
+icon:heart[2x]
+```
+Results:
+
+icon:heart[] 2x icon:heart[2x]
+
+To rotate and flip the icon:
+```
+icon:shield[rotate=270, flip=vertical]
+```
+Results:
+
+icon:shield[] rotated 90, and flipped vertical icon:shield[rotate=90, flip=vertical]
+
+You can also link to icons.
+```
+icon:download[link="https://rubygems.org/downloads/asciidoctor-1.5.2.gem"]
+```
+Results:
+
+icon:download[link="https://rubygems.org/downloads/asciidoctor-1.5.2.gem"]
+
+Lastly, you can color your icons using the role syntax.
+```
