+# Running the broker client on windows
+
+To run a fully local enrolment test you will need the following five services running and bound to different ports on localhost.
+
+ * student-mobility-broker/client
+ * student-mobility-broker/server
+ * student-mobility-home-institution-mock
+ * student-mobility-inteken-ontvanger-generiek
+ * student-mobility-inteken-ontvanger-email (or equivalent)
+
+## student-mobility-broker/client
+Default: **http://localhost:3003**
+
+https://github.com/SURFnet/student-mobility-broker (/client)
+
+Start as a Node.js application using yarn.
+
+1) Install node.js on windows
+    1) From https://nodejs.org/en download and run node-v22.14.0-x64.msi
+    2) When asked if you want to run a script to install additional build tools (python and some .net stuff for VS) answer yes
+2) Open a new powershell terminal and navigate to where you cloned student-mobility-broker, and go into the client directory (you should be able to see package.json)
+3) Run the following commands to install the dependencies (you only need to run these once) 
+```
+      npm update --legacy-peer-deps
+      npm install --legacy-peer-deps yarn
+      .\node_modules\.bin\yarn install
+```
+4) From now on you can start the client using the command ``.\node_modules\.bin\yarn dev``. 
+   This will start the client and pop a web browser window on http://localhost:3003/.
+
+The default test enrolment flow will start immediately - and fail unless the remaining four services are 
+running and configured correctly. Restart the test by reloading http://localhost:3003/ .
+
+
+## student-mobility-broker/server 
+Default **http://localhost:8091**
+
+https://github.com/SURFnet/student-mobility-broker (/server)
+
+Start as a normal Java application.
+
+Edit service-registry.yml if the other services are not running at their default locations.
+
+
+## MyAcademicID registration
+You will need to perform a MyAcademicID registration on https://tech-docs.eduxchange.eu/registration.html .
+During registration set your "Redirect URLs" to where you expect your copy of student-mobility-inteken-ontvanger-generiek 
+to run for external tests.
+You no not need to have a service running there yet (we will explain a workaround below), but keep in mind that the 
+requests hitting this endpoint will contain your real, valid, bearer tokens for your personal university account, so 
+don't set it to https://example.com/redirect_uri/ :)
+
+**The workaround**
+
+Once you have all your local service running, and you start the enrolment test by calling GET:http://localhost:3003 in 
+a web browser (use Firefox incognito to avoid the browser side session id set by the broker client), then you will 
+eventually be redirected to your institutions login page. After login, you will be redirected to \<Redirect URL\>. Be 
+sure to have your browsers network inspect panel open and copy the full path that the browser is trying to redirect to 
+(this will not show up in the address bar) - this pageload will eventually time out because no service is running at 
+\<Redirect URL\>, this is fine.  
+
+If you registered ``https://<university-domain>/redirect_uri/`` as your redirect, the url you copy will look like 
+this:
+```
+https://<university-domain>/redirect_uri/?state=...&scope=openid&code=...&iss=https%3A%2F%2Fproxy.prod.erasmus.eduteams.org&client_id=...
+```
+
+Change the schema and host/port to match your local enrolment service (see below). The updated url should look like this:
+```
+http://localhost:8092/redirect_uri/?state=...&scope=openid&code=...&iss=https%3A%2F%2Fproxy.prod.erasmus.eduteams.org&client_id=...
+```
+
+GET this url in a new browser tab, and the rest of the enrolment flow will happen normally.
+
+
+## student-mobility-home-institution-mock 
+Default **http://localhost:8076**
+
+https://github.com/SURFnet/student-mobility-home-institution-mock
+
+Start as a normal Java application.
+
+Update application.yml:
+  * ``spring.security.oauth2.resourceserver.opaque-token.introspection-uri = https://proxy.prod.erasmus.eduteams.org/OIDC/introspect``
+  * ``spring.security.oauth2.resourceserver.opaque-token.client-id = <from MyAcademicID registration>``
+  * ``spring.security.oauth2.resourceserver.opaque-token.client-secret = <from MyAcademicID registration>``
+
+
+## student-mobility-inteken-ontvanger-generiek 
+Default **http://localhost:8092**
+
+https://github.com/SURFnet/student-mobility-inteken-ontvanger-generiek
+
+Start as a normal Java application.
+
+You may need to make the following edits to application.yml
+
+If you change the jpa settings to use postgres then you will need to add ([stackoverflow](https://stackoverflow.com/questions/49110818/method-org-postgresql-jdbc-pgconnection-createclob-is-not-yet-implemented#49261146)): 
+  * ``spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation: true``  
+
+If you are not a Dutch university set:
+  * ``features.require_eduid: false``
+
+Set ``sis.user`` and ``sis.password`` to be the basic auth credentials that the enrolment service will use when calling 
+this service to request an association request me sent to the home university.
+
+Set ``backend.url``, ``backend.api_user``, and ``backend.api_password`` to be service url and basic auth credentials 
+that this service will call when it requests that the enrolment service handle the enrolment. An example of a service 
+url is http://localhost:8083/intake .
+
+To make the OAuth MyAcademicID work set:
+  * ``oidc.client-id: <from MyAcademicID registration>``
+  * ``oidc.client-secret: <from MyAcademicID registration>``
+  * ``oidc.redirect-uri: <from MyAcademicID registration>``
+  * ``oidc.authorization-uri: https://proxy.prod.erasmus.eduteams.org/OIDC/authorization``
+  * ``oidc.token-uri: https://proxy.prod.erasmus.eduteams.org/OIDC/token``
+  * ``oidc.jwk-set-uri: https://proxy.prod.erasmus.eduteams.org/OIDC/jwks``
+
+
+## your custom enrolment service
+Default **http://localhost:8093**
+
+This is where you need to write your own service that connects to your local SIS in a custom way.
+A reference implementation is provided in [student-mobility-inteken-ontvanger-email](https://github.com/SURFnet/student-mobility-inteken-ontvanger-email) 
+
+You will need to make a single endpoint called POST:/intake that accepts a JSON body: 
+```
+{
+  "person" : <https://openonderwijsapi.nl/specification/v5/docs.html#tag/person_model>
+  "offering" : <https://openonderwijsapi.nl/specification/v5/docs.html#tag/program_offering_model>
+}
+```
+
+... and is authorized using the basic auth credentials shared with student-mobility-inteken-ontvanger-generiek above.
+
+Besides deciding if the host university accepts the students enrolment request, this service must also communicate this 
+decision back to home university. Do this by calling the appropriate existing endpoints on your local copy of  
+student-mobility-inteken-ontvanger-generiek using the second set of basic auth credentials that we set in the previous 
+section.
