-To capture an event in Go, you can pass any struct implementing an `error` interface to `CaptureException()`. If you use a 3rd party library instead of native `errors` package, we'll do our best to extract a stack trace.
+To capture an event in Go, you can pass any struct implementing an `error` interface to `CaptureException()`. If you use a 3rd party library instead of native `errors` package and it implements `Unwrap() error` or `Cause() error` method, we'll follow the chain of errors and extract the stack trace from the root cause.
 
 The SDK is fully compatible with (but not limited to):
 
 - `github.com/pkg/errors`
 - `github.com/go-errors/errors`
 - `github.com/pingcap/errors`
+- `github.com/rotisserie/eris`
 
 If there is an errors package that's not working out of the box, let us know!
