+# Selenium standalone grid deployment script
+
+## Cloud provider
+
+This script use the services of Hetzner.
+
+It should be easily modified to use other cloud providers.
+
+## Dependencies
+
+You need to install `jq`, `nmap` and `hcloud`, the Hetzner cloud API CLI.
+
+On Debian
+```bash
+apt install jq nmap hcloud-cli
+```
+
+## Usage
+
+Just read the help provided by the script
+
+```bash
+./create-selenium-stack.sh -h
+```
+
+To remove all servers in the context:
+```bash
+./create-selenium-stack.sh -d -y
+```
