+# Configuration
+
+`xds-cli` configuration is defined either by environment variables or by
+setting command line options.
+
+Configuration through environment variables may also be defined in a file that
+will be sourced by `xds-cli` on start-up.
+
+Use `--config|-c` option or set `XDS_CONFIG` environment variable to specify the config file to use.
+
+So configuration is driven either by environment variables or by command line
+options or using a config file knowing that the following priority order is used:
+
+1. use option value (for example use project ID set by `--id` option),
+1. else use variable `XDS_xxx` (for example `XDS_PROJECT_ID` variable) when a
+   config file is specified with `--config|-c` option,
+1. else use `XDS_xxx` (for example `XDS_PROJECT_ID`) environment variable
+
+<!-- section-note -->
+**Note:**
+
+All parameters after a double dash (--) are considered as the command
+to execute on xds-server.
