## Github
Be awesome! Feel free to clone and use according to the licence.
If you make a useful change that can benefit others, send a
pull request! This ensures that one version has all the good stuff
and doesn't fall behind.
## Code example
See `_example/` for a simple webserver using the openID
implementation. Also, read the comment about the NonceStore towards
the top of that file. The example must be run for the openid-go
directory, like so:
go run _example/server.go
## App Engine
In order to use this on Google App Engine, you need to create an instance with a custom `*http.Client` provided by [urlfetch](https://cloud.google.com/appengine/docs/go/urlfetch/).
```go
oid := openid.NewOpenID(urlfetch.Client(appengine.NewContext(r)))
oid.RedirectURL(...)
oid.Verify(...)
```

// defined in [XRI_Resolution_2.0] are to be applied.

// Identifier. For the purposes of making OpenID Authentication

// when an OP Identifier is entered.
