+# Script Name: plex-exporter.sh
+# Version: 1.0
+# Description: Prometheus exporter for Plex Media Server providing operational
+#              metrics via the Plex API — library counts, active sessions,
+#              transcoding stats, bandwidth usage, server info, and storage
+#
+# Author: Phil Connor
+# Contact: contact@mylinux.work
+# Website: https://mylinux.work
+# License: MIT
+#
+# Prerequisites:
+#   - Plex Media Server running with API access
+#   - Plex authentication token (X-Plex-Token)
+#   - curl for API calls
+#   - netcat (nc) for HTTP mode
+#
+# Usage:
+#   # Output to stdout
+#   ./plex-exporter.sh --token YOUR_PLEX_TOKEN
+#
+#   # HTTP server mode
+#   ./plex-exporter.sh --http --token YOUR_PLEX_TOKEN
+#
+#   # Textfile collector mode
+#   ./plex-exporter.sh --textfile --token YOUR_PLEX_TOKEN
+#
+#   # Custom Plex URL
+#   ./plex-exporter.sh --url http://10.0.0.50:32400 --token YOUR_PLEX_TOKEN
+#
+# Metrics Exported:
+#   - plex_up - API reachability (1=up, 0=down)
+#   - plex_info{version,platform,hostname} - Server info
+#   - plex_library_items_total{library,type} - Items per library
+#   - plex_sessions_active - Active streams
+#   - plex_sessions_transcode - Active transcode sessions
+#   - plex_sessions_direct_play - Active direct play sessions
+#   - plex_sessions_direct_stream - Active direct stream sessions
+#   - plex_session_info{user,player,title,state,decision} - Per-session details
+#   - plex_bandwidth_bytes - Current total bandwidth
+#   - plex_transcode_speed - Current transcode speed ratio
+#   - plex_library_size_bytes{library} - Library storage usage
+#   - plex_server_update_available - Update available (1/0)
+#   - plex_exporter_duration_seconds - Script execution time
+#   - plex_exporter_last_run_timestamp - Last run timestamp
+#
+# Configuration:
+#   Default HTTP port: 9595
+#   Default Plex URL: http://localhost:32400
+#   Textfile directory: /var/lib/node_exporter
