+# WARM API
+
+## Setup
+
+### Pre-requisites
+
+Install requirements,
+
+```
+pip install -r requirements.txt
+```
+
+### Build native lib and update bindings
+
+The following command builds the iwasm library and generates the Python bindings,
+
+```sh
+bash language-bindings/python/utils/create_lib.sh
+```
+
+This will build and copy libiwasm into the package.
+
+## Examples
+
+There is a [simple example](./samples/main.py) to show how to use bindings.
+
+```
+python samples/main.py
+```
