 The options passed when the `MultiSamlStrategy` is initialized are also passed as default values to each provider. e.g. If you provide an `issuer` on `MultiSamlStrategy`, this will be also a default value for every provider. You can override these defaults by passing a new value through the `getSamlOptions` function.
 
-Using multiple providers supports `validateInResponseTo`, but all the `InResponse` values are stored on the same Cache. This means, if you're using the default `InMemoryCache`, that all providers have access to it and a provider might get its response validated against another's request. [Issue Report](!https://github.com/node-saml/passport-saml/issues/334). To amend this you should provide a different cache provider per SAML provider, through the `getSamlOptions` function.

 Please note that in the above examples, `findProvider()`, `findByNameId()`, and `findByEmail()` are an examples of functions you need to implement yourself. These are just examples. You can implement this functionality any way you see fit. Please note that calling `getSamlOptions()` should result in `done()` being called with a proper SAML Configuration (see the TypeScript typings for more information) and the `done()` callbacks for the second and third arguments should be called with an object that represents the user.

 ### generateServiceProviderMetadata( decryptionCert, signingCert )
 
-As a convenience, the strategy object exposes a `generateServiceProviderMetadata` method which will generate a service provider metadata document suitable for supplying to an identity provider. This method will only work on strategies which are configured with a `callbackUrl` (since the relative path for the callback is not sufficient information to generate a complete metadata document).
-
-The `decryptionCert` argument should be a public certificate matching the `decryptionPvk` and is required if the strategy is configured with a `decryptionPvk`.
-
-The `signingCert` argument should be a public certificate matching the `privateKey` and is required if the strategy is configured with a `privateKey`. An array of certificates can be provided to support certificate rotation. When supplying an array of certificates, the first entry in the array should match the current `privateKey`. Additional entries in the array can be used to publish upcoming certificates to IdPs before changing the `privateKey`.
+For details about this method, please see the [documentation](https://github.com/node-saml/node-saml#generateserviceprovidermetadata-decryptioncert-signingcert-) at `node-saml`.
 
 The `generateServiceProviderMetadata` method is also available on the `MultiSamlStrategy`, but needs an extra request and a callback argument (`generateServiceProviderMetadata( req, decryptionCert, signingCert, next )`), which are passed to the `getSamlOptions` to retrieve the correct configuration.
