# Tutorial - User Guide { #tutorial-user-guide }

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference so you can come back and see exactly what you need.

## Run the code { #run-the-code }

        {
            xpathTransformer = new XpathTransformer();
            xpathTransformer.setName("xpathTransformer");
            Map<String, String> featureMap = newHashMap();
            featureMap.put("http://xml.org/sax/features/namespaces", "false");
            xpathTransformer.setFeatureMap(featureMap);
            Map<String, String> propertyMap = newHashMap();
            xpathTransformer.setPropertyMap(propertyMap);

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *
* **Fewer bugs**: Reduce about 40% of human (developer) induced errors. *
