 {"name":{"first":"Tom","last":"Anderson"},"age":37,"children":["Sara","Alex","Jack"],"fav.movie":"Deer Hunter","friends":[{"first":"Janet","last":"Murphy","age":44}]}```
 ```
 
+## Spec
+
+Spec cleans comments and trailing commas from input JSON, converting it to
+valid JSON per the official spec: https://tools.ietf.org/html/rfc8259
+
+The resulting JSON will always be the same length as the input and it will
+include all of the same line breaks at matching offsets. This is to ensure
+the result can be later processed by a external parser and that that
+parser will report messages or errors with the correct offsets.
+
+The following example uses a JSON document that has comments and trailing
+commas and converts it prior to unmarshalling to using the standard Go
+JSON library.
+
+```go
+
+data := `
+{
+  /* Dev Machine */
