 This directory contains a demo springboot implementation of the SLI-API healthcheck method.
 
 To start this server, run:
-
-java -jar -DserviceLogicDirectory=src/main/resources target/sliapi-springboot-{version}.jar
+mvn -DserviceLogicDirectory=src/main/resources spring-boot:run
 
 This will start a servlet on port 8080.  To test to that servlet, post a blank
 message to that port:
 
-curl http://127.0.0.1:8080/SLI-API:healthcheck -X POST -H "Content-Type: application/json"
\ No newline at end of file
+curl http://127.0.0.1:8080/restconf/operations/SLI-API:healthcheck -X POST -H "Content-Type: application/json"
+
+Requests can also be sent to `http://localhost:8080/executeGraph`
+
+The graph details need to match a graph which has been loaded and activated
+
+An example request
+```
+{
+    "graphDetails": {
+        "module": "prov",
+        "rpc": "test",
+        "mode": "sync"
+    },
+    "input": {
+        "name": "Hello World",
+        "test": "one",
+        "mixed": "cAsE"
