# PECU Release Selector
4+
# By Daniel Puente García (Danielop95/DVNILXP)
5+
# Version: 0.0 - 14/4/2025
6+
#

# This script fetches PECU releases from GitHub and lets you pick one to run.
8+
# Stable releases are shown in green (with the first stable marked as [RECOMMENDED])
9+
# and pre-releases in yellow.
10+
#
11+
# Before starting, it checks that curl and jq are installed and verifies network
12+
# connectivity, letting you know what's happening along the way.
13+
#
14+
# Usage: Run as root on your Proxmox server.
