   There are a few rules in particular that will make it much easier to do
   *an incremental upgrade* using the Angular 2 `upgrade` module:
 
-  * The [Rule of 1](https://github.com/johnpapa/angular-styleguide#single-responsibility)
+  * The [Rule of 1](https://github.com/johnpapa/angular-styleguide/blob/master/a1/README.md#single-responsibility)
     states that there should be one component per file. This not only makes
     components easy to navigate and find, but will also allow us to migrate
     them between languages and frameworks one at a time. In this example application,
     each controller, factory, and filter is in its own source file.
-  * The [Folders-by-Feature Structure](https://github.com/johnpapa/angular-styleguide#style-y152)
-    and [Modularity](https://github.com/johnpapa/angular-styleguide#modularity)
+  * The [Folders-by-Feature Structure](https://github.com/johnpapa/angular-styleguide/blob/master/a1/README.md#folders-by-feature-structure)
+    and [Modularity](https://github.com/johnpapa/angular-styleguide/blob/master/a1/README.md#modularity)
     rules define similar principles on a higher level of abstraction: Different parts of the
     application should reside in different directories and Angular modules.
