+# ansible-pilote
+
+Ansible repository to manage `pilote`, a Raspberry Pi host running monitoring
+software at home. This host was described in my [Journey of a Home-based
+Personal Cloud Storage
+Project](https://julien.riou.xyz/socallinuxexpo2024.handout.html) talk. This is
+a personal repository that you can use as an example.
+
+# Requirements
+
+1. Configure network
+1. Configure password for root user
+1. Allow password for root user on SSH
+1. Enable and start ssh.service
+1. Write IP address in `inventory/hosts` file
+1. Update variables in `group_vars/pilote.yml` file
+
+# First run
+
+```
+ansible-playbook --ask-pass main.yml
+```
+
+# Subsequent runs
+
+```
+ansible-playbook main.yml
+```
+
+# Variables
+
+See [documentation](group_vars/README.md).
