 Notice that you can pass in `fmt.Sprintf` arguments after the expected JSON structure.
 
-`Asserter.Assert()` supports assertions against the following payload data types:
-
-- `string`
-- `*json.RawMessage`
-- `*http.Request`
-- Any `struct` with `json:` tags
-
-### Advanced usage
-
-#### Validate presence, not value
-
-Sometimes you do not care about the value of a key, but only its presence. Take timestamps and UUIDs for example:
-
-```json
-{
-    "uuid": "cb5230fc-f98f-4c63-abb7-d0588295983b",
-    "timestamp": "2018-10-26T23:43:50+00:00"
-}
-```
-
-The properties here may be non-deterministic and difficult to test against.
-In this case you may replace the expected value with `"<PRESENCE>"` to assert its presence, but not its value:
-
-```json
-{
-    "uuid": "<PRESENCE>",
-    "timestamp": "<PRESENCE>"
-}
-```
-
-`"<PRESENCE>"` works for any key, regardless of type.
-
-#### Advanced configuration
-
-Instead of calling `jsonassert.New(t)` you may call `jsonassert.NewWithConfig(t, config)`, which allows you to pass in a `jsonassert.Configuration` struct.
-
-```go
-{
-    // IgnoreArrayOrder, when set, will check that the values present in the
-    // actual JSON payload matches the assertion payload, but will ignore the
-    // order of these elements. Applies to all arrays in the payload.
-    IgnoreArrayOrder: true,
-
-    // When enabled will pretty-print the entire given JSON payload for any
-    // assertion failures.
-    Verbose: true,
-}
-```
+`Asserter.Assert()` currently supports assertions against strings only.
