 # Sleeper Function Image
 
-This images compares the payload info with the header.
+This function sleeps for some number of seconds that you pass in. 
 
-## Requirements
-
-- IronFunctions API
-
-## Development
-
-### Building image locally
+Test it with:
 
-```
-# 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
+```sh
+fn build
+echo '{"sleep": 5}' | fn run
 ```
