+
+## Introduction
+This directory contains a Helm chart to deploy [Parca Server](https://github.com/parca-dev/parca),
+used for Open Source infrastructure-wide continous profiling.
+
+## Installation
+
+To install the chart with the release name `my-release`, you can clone the git repo and run the command:
+```console
+helm install --name my-release ./charts/parca-server
+```
+
+You can override parameters using the `--set key=value[,key=value]` argument to `helm install`,
+e.g., to disable service account creation:
+
+```console
+helm install --name my-release ./charts/parca-server --set serviceAccount.create=false
+```
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+```console
+helm install --name my-release -f myvalues.yaml ./charts/parca-server
+```
+
+### Installing from the Timescale Helm Repo
+
+We have a Helm Repository that you can use, instead of cloning this Git repo. 
+
+First add the repository with:
+```console
+helm repo add timescale 'https://charts.timescale.com'
+```
+
+Next proceed to install the chart:
+
+```console
+helm install my-release timescale/parca-server
+```
+
+To keep the repo up to date with new versions you can do:
+```console
+helm repo update
+```
