-A Helm chart for Kubernetes
+Open Source Infrastructure-wide continuous profiling
+
+**Homepage:** <https://parca.dev/>
+
+## Source Code
+
+* <https://github.com/rlex/helm-charts>
+
+### Usage
+
+Please consult official docs on usage.  
+Chart includes prometheus-style discovery rule with annotations:  
+
+If you want k8s prometheus-like scraping for pprof endpoints, all you need is to add annotations for pod:
+```
+parca.dev/scrape: 'true'
+```
+
+to furter adjust scope of scraping, you can use
+```
+parca.dev/port: 'debug'
+```
