+# Fluxcloud
+
+Fluxcloud is a tool to receive events from the [Weave flux](https://github.com/weaveworks/flux).
+
+Fluxcloud is a valid upstream for Weave, allowing you to send Flux events to Slack or a
+webhook without using Weave Cloud.
+
+## Introduction
+
+This chart bootstraps a [Flux](https://github.com/justinbarrick/fluxcloud) deployment on
+a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+## Installation
+
+I assume if you got here you have already installed at least Flux using Helm. This is of course very similar (and simpler).
+
+
+### Installing the Chart
+
+```sh
+helm install incubator/fluxcloud
+```
+
+### Configuration
+
+The following configuration values are defaults that can be modified:
+
+```yaml
+replicaCount: 1
+
+imageRepository: justinbarrick/fluxcloud
+imageTag: v0.3.4
+imagePullPolicy: IfNotPresent
+
+servicePort: 80
+serviceTargetPort: 3032
+
+extraEnvs: []
+#extraEnvs:
+#- name: SLACK_URL
+#  value: "https://hooks.slack.com/services/WEBHOOK_URL"
+#- name: SLACK_CHANNEL
+#  value: "#kubernetes" # Or multiple channels (comma separated <channel>=<namespace>). e.g.: value: "#kubernetes=*,#team=team"
+#- name: SLACK_USERNAME
+#  value: Flux Deployer
+#- name: SLACK_ICON_EMOJI

+#- name: GITHUB_URL
+#  value: "https://github.com/justinbarrick/fluxcloud/"
+#- name: LISTEN_ADDRESS
+#  value: ":3032"
+```
