+# Hacker Slides
+
+### Hack together simple slides
+
+<!-- .slide: data-transition="zoom" -->
+
+---
+
+## The Basics
+
+- Separate slides using '`---`' on a blank line
+- For vertical slides use '`--`'  
+- Write github flavored markdown
+- Click 'Present' (top right) when you're ready to talk
+
+---
+
+## Quick tips
+
+- There is also a speaker view, with notes - press '`s`'
+- Press '`?`' with focus on the presentation for shortcuts
+- <em>You can use html when necessary</em>
+- Share the 'Present' URL with anyone you like!
+
+Note:
+- Anything after `Note:` will only appear here
+
