+
+## Why this another fluentd image?
+
+- We have custom plugins like slack plugin that we want to use with fluentd, which aren't available in the original image
+- We've updated the dockerfile to allow custom config paths via environment variables
+- We've bundled a couple of source, filters and matches with this image that we want to use with kubernetes
+
+## What it contains
+
+### Source
+
+The image contains a lot of predefined sources related to kubernetes, docker and systemd. Following list contains all of them:
+
+- cluster-autoscaler
+- docker
+- etcd
+- glbc
+- kube-apiserver-audit
+- kube-apiserver
+- kube-controller-manager
+- kube-proxy
+- kube-rescheduler
+- kube-scheduler
+- kubelet
+- kubernetes
+- minion
+- startupscript
+- systemd-bootkube
+- systemd-docker
+- systemd-kubelet
+
+### Filter
+
+This image only contains `kubernetes-metadata` filter for now.
+
+### Match
+
+We've included `elasticsearch` and `fluentd` matches in this image.
+
