+# Extending _why's Legacy
+
+![Would _why have a beard if he existed now](image.png)
+
+The leading mission for Scarpe has been to implement as much backwards compatibility as possible for _why's original
+Shoes library. This remains true. _why's taste and DSL are celebrated and preserved. However, at the discretion of
+core maintainers, new features may be added. They must be approved by Noah Gibbs or Nick Schwaderer, and described
+in this file. They cannot conflict or damage backwards compatibility with the original Shoes library.
+
+## Page Navigation
+
+Similar to URL navigation. see `url_navigation_single_app.rb` for an example. Unlike URLs, they do not accept parameters,
+only the name of the page. They are simply declared and named in blocks.
+
+```ruby
+Shoes.app do
+  page(:home) do
+    title "Home Page"
+    para "Welcome to the home page"
+    button "Go to another page" do
+      visit(:another_page)
+    end
+  end
+
+  page(:another_page) do
+    title "Another Page"
+    para "Welcome to another page"
+    button "Go to home page" do
+      visit(:home)
+    end
+  end
+end
