 A helm chart to setup [Pixelfed](https://pixelfed.org/). Uses matt's docker [image](ghcr.io/mattlqx/docker-pixelfed) for now.
+
+
+## TLDR
+
+```bash
+# add the chart repo to your helm repos
+helm repo add pixelfed https://small-hack.github.io/pixelfed-chart
+
+# download the values.yaml and edit it with your own values such as YOUR hostname
+helm show values pixelfed/pixelfed > values.yaml
+
+# install the chart
+helm install --namespace pixelfed --create-namespace pixelfed/pixelfed --values values.yaml
+```
