+# CF Helm Charts 
+
+This repository contains Helm Charts commonly used and developed at the Cardano Foundation.
+
+Use at your own risk.
+
+## Helm Chart Build
+
+This repo is configured following the Helm Chart docs available [here](https://helm.sh/docs/topics/chart_repository/)
+
+### Building a chart
+
+Assuming the folder containing all the charts is called `charts`, you can build and index new charts or updates as follows.
+
+Packaging a chart:
+
+```bash
+helm package path/to/my_chart/
+```
+
+Deploying and indexing a chart:
+
+```bash
+mv my_chart-x.y.z.tgz charts/
+helm repo index charts --url https://cardano-foundation.github.io/cf-helm-charts/
+```
+
+Add new or modified files to git, push changes. 
+
+Congrats, you've deployed a new or updated chart to our repository
