+# Tomcat
+
+> Apache Tomcat, often referred to as Tomcat, is an open-source web server and servlet container developed by the Apache Software Foundation. Tomcat implements several Java EE specifications including Java Servlet, JavaServer Pages, Java EL, and WebSocket, and provides a "pure Java" HTTP web server environment for Java code to run in.
+
+Based on the [Bitnami Tomcat](https://github.com/bitnami/bitnami-docker-tomcat) image for docker, this Chart bootstraps a [Tomcat](https://tomcat.com/) deployment on a [Kubernetes](http://kubernetes.io) cluster using [Helm](https://helm.sh).
+
+## Persistence
+
+For persistence of the Tomcat data, mount a [storage volume](http://kubernetes.io/docs/user-guide/volumes/) at the `/app` path of the Tomcat pod.
+
+By default the Tomcat Chart mounts an [emptyDir](http://kubernetes.io/docs/user-guide/volumes/#emptydir) volume.
+
+## Configuration
+
+To edit the default Tomcat configuration, run
+
+```bash
+$ helm edit tomcat
+```
+
+Configurable parameters can be specified in `tpl/values.toml`. If not specified default values as defined by the [Bitnami Tomcat](https://github.com/bitnami/bitnami-docker-tomcat) image are used.
+
+> Tip: If you have issues running the above command, add `se autochdir` to your `~/.vimrc` profile or simply edit `~/.helm/workspace/charts/tomcat/tpl/values.toml` in your favourite editor.
+
+Finally, generate the chart to apply your changes to the configuration.
+
+```bash
+$ helm generate tomcat
+```
+
+## Cleanup
+
+To delete the Tomcat deployment completely:
+
+```bash
+$ helm uninstall -n default tomcat
+```
