+# Setting Up Hot Reload
+
+1. Hot reloading allows much faster iteration times inside of rsx calls by interperting them and streaming the edits.
+2. It is useful when changing the styling/layout of a program, but will not help with changing the logic of a program.
+3. Currently the cli only implements hot reloading for the web renderer.
+
+# Setup
+Install [dioxus-cli](https://github.com/DioxusLabs/cli).
+Enable the hot-reload feature on dioxus:
+```toml
+dioxus = { version = "*", features = ["web", "hot-reload"] }
+```
+
+# Usage
+1. run:
+```
+dioxus serve --hot-reload
+```
+2. change some code within a rsx macro
+3. open your localhost in a browser
+4. save and watch the style change without recompiling
+
+# Limitations
+1. The interperter can only use expressions that existed on the last full recompile. If you introduce a new variable or expression to the rsx call, it will trigger a full recompile to capture the expression.
+2. Components and Iterators can contain abritary rust code, and will trigger a full recompile when changed.
