+### Using pflag with go test
+`pflag` does not parse the shorthand versions of go test's built-in flags (i.e., those starting with `-test.`).
+For more context, see issues [#63](https://github.com/spf13/pflag/issues/63) and [#238](https://github.com/spf13/pflag/issues/238) for more details.
+
+For example, if you use pflag in your `TestMain` function and call `pflag.Parse()` after defining your custom flags, running a test like this:
+```bash
+go test /your/tests -run ^YourTest -v --your-test-pflags
+```
+will result in the `-v` flag being ignored. This happens because of the way pflag handles flag parsing, skipping over go test's built-in shorthand flags.
+To work around this, you can use the `ParseSkippedFlags` function, which ensures that go test's flags are parsed separately using the standard flag package.
+
+**Example**: You want to parse go test flags that are otherwise ignore by `pflag.Parse()`
+```go
+import (
+	goflag "flag"
+	flag "github.com/spf13/pflag"
+)
+
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+
+func main() {
+	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
+    flag.ParseSkippedFlags(os.Args[1:], goflag.CommandLine)
+	flag.Parse()
+}
+```

 After all flags are defined, call
