+# Microscope
+
+Microscope is a simple social news app that lets you share links, comment, and vote on them.
+
+It was built with [Meteor](http://meteor.com) as a companion app to [The Meteor Book](http://themeteorbook.com), and is the "little brother" of [Telescope](http://telesc.pe), the (much more complex) open-source social news app that was the inspiration for the book.
+
+Microscope itself is free and open-source, and is a good example of common Meteor app patterns such as:
+
+- Routing
+- User Accounts
+- Notifications
+- Errors
+- Publications/Subscriptions
+- Permissions
+
+## This Repository
+
+The commits to this repository are organized in a very linear fashion, corresponding to progress throughout the book. Commits are tagged in the format `chapterX-Y`, indicating the `Y`th commit of chapter `X`.
+
+Also, note that as the book focuses on _development_, all CSS is committed in a single commit early on.
+
+### Branches
+
+There are 2 branches in this repository which correspond to advanced code that is covered in sidebars of the book, and outside of the main code progression. They are tagged `sidebarX-Y`, corresponding to the sidebar number in the book.
+
+### Developing on Nitrous.IO
