+# Trackers Configuration Example
+# Copy this file to config.toml and adjust values for your setup
+
+# HTTP server port
+# Default: 8080
+port = 8080
+
+# Directory for caching tracker lists
+# Used to persist tracker data between restarts and handle source failures
+# Default: "cache"
+cache_dir = "cache"
+
+# Interval between polling each source
+# Valid units: s (seconds), m (minutes), h (hours)
+# Examples: "30s", "5m", "1h", "90m"
+# Default: "60m"
+poll_interval = "60m"
+
+# List of tracker sources to aggregate
+# Supported schemes:
+#   - http:// / https:// - Remote HTTP endpoints
+#   - file:// - Local files (e.g., file:///path/to/trackers.txt)
+#
+# Each source should return tracker URLs, one per line
+# Blank lines and duplicates are automatically filtered
+sources = [
+    "https://example.com/trackers/all.txt",

+
+# Proxy Configuration
+# ==================
+# HTTP requests automatically respect standard proxy environment variables:
+#
+#   HTTP_PROXY  - Proxy for HTTP requests (e.g., http://proxy.example.com:8080)
+#   HTTPS_PROXY - Proxy for HTTPS requests (e.g., http://proxy.example.com:8080)
+#   NO_PROXY    - Comma-separated list of hosts to bypass proxy (e.g., localhost,127.0.0.1)
+#
+# Example usage:
+#   export HTTP_PROXY=http://proxy.example.com:8080
+#   export HTTPS_PROXY=http://proxy.example.com:8080
+#   export NO_PROXY=localhost,127.0.0.1,.local
+#   ./trackers -config config.toml
