 # Examples
 
-This folder contains multiple different example programs for WARDuino.
-All WebAssembly text files (.wat) from the examples can be run without additional hardware, by using the emulated version of WARDuino.
+This folder contains the code for all examples from the [tutorials](https://topllab.github.io/WARDuino/guide/examples/) from the documentation website.
+
+Additionally, the `wat` folder contains a simple example in textual WebAssembly, which relies on no other higher-level languages.
+
+## Running the examples
+
+All WebAssembly binaries (.wasm) from the examples can be run without additional hardware, by using the emulated version of WARDuino.
 This version is packaged as a command line interface.
 
 ```bash
-./wdcli --file example.wat
+./wdcli --file example.wasm
 ```
