 # go-errors
 
-simple but powerful errors library that allows easy wrapping and stacktracing of errors.
-
-to disable stacktraces set the `notrace` build tag.
\ No newline at end of file
+powerful errors library with a simple API that allows:
+- accessing all the standard library errors functions
+- wrapping of errors
+- adding values to errors, in a similar manner to contexts
+- including calling function prefix when tag=errcaller is set
+- including stacktrace with error when tag=errtrace is set
