+# Walkthrough of the Hello World Example Internals
+
+This walkthrough will take you through the internals of the Hello World example program. It will explain how major parts of Dioxus interals interact with each other to go from a source file to a running program.
+
+## The Source File
+
+We start will a hello world program. This program renders a desktop app with the text "Hello World" in a webview.
+
+```rust
+{{#include ../../../../../examples/readme.rs}}
+```

+
+## The rsx! Macro
+
+Before rust runs the program, it will expand all macros. Here is what the hello world example looks like expanded:
+
+```rust
+{{#include ../../../examples/readme_expanded.rs}}
+```
+
+The rsx macro separates the static parts of the rsx (the template) and the dynamic parts (the dynamic_nodes and dynamic_attributes).
+
+The static template only contains the parts of the rsx that cannot change at runtime with holes for the dynamic parts:
