+# Introduction
+
+This is sample project to demonstrate how to use the docker to run the connector.
+This examples is for http connector but can be used for any connector.
+
+# To build image
+
+To build docker image run:
+```
+make build
+```
+
+This will copy following files from your local file system:
+- your current fluvio profile
+- connector.yaml
+
+The connector.yaml is connector config for http source
+
+
+# To run image
+
+To run image, run:
+```
+make run
+```
+
+This setup will run `host` network mode. This means that connector will be able to access the local network.  If you want to run in different network mode, you can modify the `Makefile` to change the network mode.
