apus is a wiki system which features instant updates. Namely, your changes are broadcasted to other clients.
Copy config.yaml.sample as config.yaml.
Create an OAuth app on GitHub and obtain a client id and secret, then set clientId and clientSecret fields in config.yaml.
Prepare a SSL certificate and a key, and replace the values of tlsCertificate and tlsKey with the paths.
Now you can start a server:
stack build
stack exec apus-exe config.yaml
