+== General Configuration Format
+
+The APEX configuration file is a JSON file containing a few main blocks for different parts of the configuration.
+Each block then holds the configuration details.
+The following code shows the main blocks:
+
+[source%nowrap,json]
+----
+{
+  "engineServiceParameters":{
+    ... // <1>
+    "engineParameters":{ <2>
+      "engineParameters":{...}, <3>
+      "contextParameters":{...} <4>
+    }
+  },
+  "eventInputParameters":{ <5>
+    "input1":{ <6>
+      "carrierTechnologyParameters":{...},
+      "eventProtocolParameters":{...}
+    },
+    "input2":{...}, <7>
+      "carrierTechnologyParameters":{...},
+      "eventProtocolParameters":{...}
+    },
+    ... // <8>
+  },
+  "eventOutputParameters":{ <9>
+    "output1":{ <10>
+      "carrierTechnologyParameters":{...},
+      "eventProtocolParameters":{...}
+    },
+    "output2":{ <11>
+      "carrierTechnologyParameters":{...},
