+# keylimectl Configuration File
+#
+# This file contains all available configuration options for keylimectl,
+# the modern command-line tool for Keylime remote attestation.
+#
+# Configuration files are completely optional. keylimectl will work out-of-the-box
+# with sensible defaults if no configuration file is provided.
+#
+# Configuration precedence (highest to lowest):
+# 1. Command-line arguments
+# 2. Environment variables (KEYLIME_*)
+# 3. Configuration files (this file)
+# 4. Default values
+#
+# This file uses TOML format. For more information about TOML syntax,

+# CONFIGURATION FILE LOCATIONS
+#
+# keylimectl searches for configuration files in this order:
+# 1. Explicit path provided via -c/--config (required to exist)
+# 2. ./keylimectl.toml (current directory)
+# 3. ./keylimectl.conf (current directory)
+# 4. /etc/keylime/keylimectl.conf (system-wide)
+# 5. /usr/etc/keylime/keylimectl.conf (alternative system-wide)
+# 6. ~/.config/keylime/keylimectl.conf (user-specific)
+# 7. ~/.keylimectl.toml (user-specific)
+# 8. $XDG_CONFIG_HOME/keylime/keylimectl.conf (XDG standard)
+#
+# If no configuration files are found, keylimectl works with defaults.
