+# MongoDB
+
+> MongoDB is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.
+
+Based on the [Bitnami MongoDB](https://github.com/bitnami/bitnami-docker-mongodb) image for docker, this Chart bootstraps a [MongoDB](https://mongodb.com/) deployment on a [Kubernetes](http://kubernetes.io) cluster using [Helm](https://helm.sh).
+
+## Persistence
+
+For persistence of the MongoDB data, mount a [storage volume](http://kubernetes.io/docs/user-guide/volumes/) at the `/bitnami/mongodb/data` path of the MongoDB pod.
+
+By default the MongoDB Chart mounts an [emptyDir](http://kubernetes.io/docs/user-guide/volumes/#emptydir) volume.
+
+## Configuration
+
+To edit the default MongoDB configuration, run
+
+```bash
+$ helm edit mongodb
+```
+
+Configurable parameters can be specified in `tpl/values.toml`. If not specified default values as defined by the [Bitnami MongoDB](https://github.com/bitnami/bitnami-docker-mongodb) 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/mongodb/tpl/values.toml` in your favourite editor.
+
+Finally, generate the chart to apply your changes to the configuration.
+
+```bash
+$ helm generate mongodb
+```
+
+## Cleanup
+
+To delete the MongoDB deployment completely:
+
+```bash
+$ helm uninstall -n default mongodb
+```
