+
+This guide will help you set up Kurtosis in your own cloud and exposing it using one of your subdomains e.g. `kurtosis.<your domain>.com`
+
+I. Prerequisites
+-----------------
+
+1. Public facing gateway (e.g. AWS ALB) supporting the Kurtosis subdomain with certificate. The certificate should support the subdomain name and a wildcard subdomain prefix `*.<subdomain>` since the service port URLs format is `port-service-enclave.<subdomain>`. The gateway should terminate TLS.
+2. Host running Ubuntu to install and configure Kurtosis on. The host should be on a private subnet receiving traffic from the Gateway on port 80. Healthchecks should use the `/status` URL.

+
+II. Kurtosis Installation
+-----------------
+
+We provide an install script setting up Docker, Nginx and Kurtosis. The script takes as arguments your subdomain name, a username and password for HTTP basic authentication.
+
+```bash
+curl -s https://raw.githubusercontent.com/kurtosis-tech/kurtosis-cloud-config/main/self-hosting-setup.sh | bash -s <subdomain name> <username> <password>
+```
