# Resilient web sessions example
2+
3+
This example is associated with blog post (link will be posted post-release).
4+
5+
To start a sample cluster, go to `docker` folder, create `licensekey.env` with `HZ_LICENSEKEY=<your key here>` and then run `docker-compose up`.
6+
7+
Individual nodes can be started or stopped using `docker up/down <instance>`, where `<instance>` is either `london-cluster` or `nyc-cluster`.
8+
9+
After that, you can run `Main` class.
