+You need to have Python 3 installed.
+
+Run PostgreSQL database on `localhost:5432` with user `db`, password `db` and
+database `openlobby`. You can provide different address in environment variable
+`DATABASE_DSN`.

+Run Elasticsearch server

+### Local run
+
+Clone this repository and run:
 
 1. `make init-env` - prepares Python virtualenv in dir `.env`
 2. `source .env/bin/activate` - activates virtualenv
 3. `make install` - installs requirements and server in development mode

 ### Testing
 
 Run: `pytest`
 
-Expects Elasticsearch for tests running on `localhost:9200` (can be override by
-environment variable `ELASTICSEARCH_DSN`). Tests creates random indices with
-prefix `test_` and deletes all indices matching `test_*` on teardown.
+For full test suite run you have to provide OpenID Provider issuer URL which
+allows client registration. For example you can run Keycloak sever locally:
+`docker run -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=pass -p 8080:8080 --rm jboss/keycloak`
+
+Login into Keycloak admin console `http://localhost:8080/auth/admin/`
+(as admin/pass) and go to Realm Settings -> Client Registration -> Client 
+Registration Policies -> Trusted Hosts. There add `localhost` to "Trusted 
+Hosts", turn off "Host Sending Client Registration Request Must Match" and save
+it.
+
+Now run: `pytest --issuer=http://localhost:8080/auth/realms/master`
