 *Note:* It is a good idea to put the `PATH` export line into your `.bashrc` or
 `.zshenv`.
 
+### Build the applications
+
 Use `make` to build the web app resources and applications:

 ```shell
 go install github.com/nicksnyder/go-i18n/v2/goi18n@latest
 make
 ```
 
+## Deployment options
+
+There are two deployment options for the Hydra server and for the custom applications:
+
+1. local deployment
+2. Vagrant deployment
+
+You only need one of these options.
+
+Both options use [ansible](https://docs.ansible.com/) to:
+
+- setup the Hydra authorization server
+- setup IDP (provides login and consent screens)
+- setup demo application
+- setup OpenID Connect client registration application
+
+### Local deployment

 Use `ansible-playbook` to deploy Hydra, IDP, Client registration and the demo
 application:

+You can also use [Vagrant](https://www.vagrantup.com/) with the

+Note: You may also want to configure your browser to trust the CA certificate
+in `/usr/local/share/ca-certificates/mkcert-vagrant-oidc.crt`. If you do not
+add this trust configuration you will get browser warnings for an unknown
+certificate authority.
+
+## Testing your local setup
+
+### Test the authorization server
+
+Request the OpenID connect auto discovery information from Hydra
+
+```shell
+curl https://hydra.cacert.localhost:4444/.well-known/openid-configuration | python3 -m json.tool
+```
+
+This should give you a JSON document with information about the authorization server.

+### Test the identity provider

+Open

+this should ask you for a CAcert class 3 client certificate and should render a
