+not yet support Daisy Seed(with AK4556), Daisy Patch SM.
+
+## Run Examples
+
+The first thing we'd like you to do is to run one of the examples on your Daisy board.
+
+### Prerequisites
+
+You can choose your preferred toolset to run the examples, but we recommend you to install [probe-rs](https://github.com/probe-rs/probe-rs)
+
+### Which Daisy Board You Have?
+
+- If you have `rev5`, it's defaulted.So you don't have to care about options.
+- If you have `rev7`, add `--features=seed_1_2 --no-default-features`  option each time you run an example.
+
+### Choose a Example You Want to Run 
+
+You can run examples with `cargo run --example <example_name>`.
