+guacamole
+=========
+
+## TL;DR;
+
+```console
+$ helm repo add beryju https://charts.beryju.io
+$ helm install guacamole beryju/guacamole
+```
+
+Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.
+
+This is a fork of https://artifacthub.io/packages/helm/halkeye/guacamole, but updated to support newer versions and more settings.
+
+### Dependencies
+
+This chart has a dependency on ``postgresql`` to be up and running _before_ this chart is deployed. The init-container will not fail if the ``postgresql`` service is not found.
+
+Sample ``postgresql`` install which works with the defaults of this chart:
+```console
+helm install postgresql bitnami/postgresql \
+ --set auth.username=guacamole \
+ --set auth.password=password \
+ --set auth.postgresPassword=password \
+ --set auth.database=guacamole --wait
+```
+
+## Changelog
+
+1.3.3 - Fixed ingress api and documented postgresql dependency
+
+1.2.3 - Make guacamole run in ROOT context
+
+0.2.3 - Add support for custom envs
+
+0.2.2 - Update liveness and readiness probe path
+
+0.2.1 - helm-docs doesn't add a tl;dr section, so add it manually
+
+0.2.0 - Apparently I didn't actually use it before, i was running an old copy
+
+* Fixed services to expose the ports properly
+* Auto create the db on init if possible
