-This is a worker that just echoes the "input" param in the payload.
+# Sleeper Function Image
 
-eg:
+This images compares the payload info with the header.
 
-This input:
+## Requirements
 
-```json
-{
-  "sleep": 5
-}
-```
+- IronFunctions API
 
-Will make this container sleep for 5 seconds.
+## Development

-## Building Image
-
-Install [dj](https://github.com/treeder/dj/), then run:
+### Building image locally
 
 ```
-docker build -t iron/sleeper .
-docker run -e 'PAYLOAD={"sleep": 5}' iron/sleeper
+# SET BELOW TO YOUR DOCKER HUB USERNAME
+USERNAME=YOUR_DOCKER_HUB_USERNAME
+
+# build it
+./build.sh
+```
+
+### Publishing to DockerHub
+
+```
+# tagging
+docker run --rm -v "$PWD":/app treeder/bump patch
+docker tag $USERNAME/func-sleeper:latest $USERNAME/func-sleeper:`cat VERSION`
+
+# pushing to docker hub
+docker push $USERNAME/func-sleeper
+```
+
+### Testing image
+
+```
+./test.sh
+```
+
+## Running it on IronFunctions
+
+### Let's define some environment variables
+
+```
+# Set your Function server address
+# Eg. 127.0.0.1:8080
+FUNCAPI=YOUR_FUNCTIONS_ADDRESS
+```
+
+### Running with IronFunctions
+
+With this command we are going to create an application with name `sleeper`.
+
+```
+curl -X POST --data '{
+    "app": {
+        "name": "sleeper",
+    }
+}' http://$FUNCAPI/v1/apps
+```
+
+Now, we can create our route
+
+```
+curl -X POST --data '{
+    "route": {
+        "image": "'$USERNAME'/func-sleeper",
+        "path": "/sleeper",
+    }
+}' http://$FUNCAPI/v1/apps/sleeper/routes
+```
+
+#### Testing function
+
+Now that we created our IronFunction route, let's test our new route
+
+```
+curl -X POST --data '{"sleep": 5}' http://$FUNCAPI/r/sleeper/sleeper
 ```
