## Welcome to Apache Tomcat!

### What Is It?

The Apache Tomcat® software is an open source implementation of the Java
Servlet, JavaServer Pages, Java Expression Language and Java WebSocket
technologies. The Java Servlet, JavaServer Pages, Java Expression Language and
Java WebSocket specifications are developed under the
[Java Community Process](https://jcp.org/en/introduction/overview).

The Apache Tomcat software is developed in an open and participatory
environment and released under the
[Apache License version 2](https://www.apache.org/licenses/). The Apache Tomcat
project is intended to be a collaboration of the best-of-breed developers from
around the world. We invite you to participate in this open development
project. To learn more about getting involved,
[click here](https://tomcat.apache.org/getinvolved.html) or keep reading.

Apache Tomcat software powers numerous large-scale, mission-critical web
applications across a diverse range of industries and organizations. Some of
these users and their stories are listed on the
[PoweredBy wiki page](https://wiki.apache.org/tomcat/PoweredBy).

Apache Tomcat, Tomcat, Apache, the Apache feather, and the Apache Tomcat
project logo are trademarks of the Apache Software Foundation.
