+
+`sphinx-helm` is a [Sphinx](https://www.sphinx-doc.org/) plugin for automatically generating documentation for your [Helm charts](https://helm.sh/).
+
+It will use the chart's `Chart.yaml` and `values.yaml` files in order to
+generate the content in a markup language of your choice.
+
+## Features
+
+- Render documentation from your `Chart.yaml` and `values.yaml` files.
+- Sphinx extension for including in Python documentation.
+- Works with `rst` and `md` documentation source files.
+
+## Installation
+
+```console
+$ pip install sphinx-helm
+```
+
+## Example
+
+Create an example `hello-world` Helm chart with `helm create`.
+
+```console
+$ helm create hello-world
+Creating hello-world
+```
+
+- Enable the plugin in your Sphinx ``conf.py`` file:
+
+```python
+extensions = ['sphinx-helm.ext']
+```
+
+- Now you can use the `helm` directive wherever you wish in your documentation.
+
+```rst
+.. helm:: path/to/hello-world
+```
+
+```{note}
+sphinx-helm paths are relative to the root of your documentation.
+```
+
+## Example
+
+*The following was autogenerated from the simple nginx example chart in sphinx-helm's test suite.*
+
+
+```{helm} ../sphinx_helm/tests/mockcharts/simple
+
+```
