-### Handling errors
-
-Throwing calls throw either an `AudioDecoder.Error`
-
-``` swift
-do {
-    let fileURL = URL(fileURLWithPath: "Invalid.mp3")
-    try AudioFingerprint(from: fileURL)
 } catch {
-    // AudioDecoder.Error.invalidFile
+    // AcoustID.Error
 }
 ```
 
-Or an `AudioFingerprint.Error`
+### Handling errors
 
-``` swift
-do {
-    try AudioFingerprint(from: "Invalid", duration: 46.0)
-} catch {
-    // AudioFingerprint.Error.invalidFingerprint
-}
-```
+The `AudioFingerprint` class throws either `AudioDecoder.Error` or `AudioFingerprint.Error` errors, the `AcoustID` class throws `AcoustID.Error` errors.
