+## Next Steps
+
+Here is some information if you want to modify the quickstart to test ORY Kratos in with different settings.
+
+__Using different databases__
+
+If you want to run the quickstart with PostgreSQL, run the following docker-compose:
+`docker-compose -f quickstart.yml -f quickstart-standalone.yml -f quickstart-postgres.yml up --build --force-recreate`
+
+If you want to run the quickstart with CockroachDB, run the following docker-compose:
+`docker-compose -f quickstart.yml -f quickstart-standalone.yml -f quickstart-crdb.yml up --build --force-recreate`
+
+If you want to run the quickstart with MySQL, run the following docker-compose:
+`docker-compose -f quickstart.yml -f quickstart-standalone.yml -f quickstart-mysql.yml up --build --force-recreate`
+
+__Changing ports__
+
+If you want to change ports for the SelfService-UI, you need to change them in `quickstart.yml` as well as in the `contrib/quickstart/kratos/email-password/.kratos.yml` accordingly. 
+
+Note that you also need to change the ports for flows (error, settings, recovery, verification, logout, login, registration).
+
+The same procedure applies if you want to change ports for the Public UI/Admin UI or the Mailslurper.
+
+__Hooks__
+
+If you want to change the redirects happening after registration,login or a settings change, take a look at this document: [Hooks](https://www.ory.sh/kratos/docs/self-service/hooks/index/).
+
+If you delete the `session` hook from `kratos.yml`, the user will _not_ be immediately signed in after registration. 
+
+__OIDC__ 
+
+If you want to test ORY Kratos integration with different OIDC providers, you will find more information in this document: [OIDC](https://www.ory.sh/kratos/docs/guides/sign-in-with-github-google-facebook-linkedin)
