+Main commands
+=============
+
+The **ArGaze** package comes with top-level commands.
+
+!!! note
+      *Use -h option to get command arguments documentation.*
+
+## Load
+
+Load and execute any [ArContext](../../argaze.md/#argaze.ArFeatures.ArContext) from a JSON CONFIGURATION file
+
+```shell
+python -m argaze load CONFIGURATION
+```
+
+This command should open a GUI window to display the image of the context's pipeline.

+
+### Send command
+
+Use -p option to enable pipe communication at given address:
+
+```shell
+python -m argaze load CONFIGURATION -p /tmp/argaze
+```
+
+Open another tab in the **same** Terminal window then, you can send any Python command into the pipe.
+
+For example:
+
+* Print context:
+```shell
+echo "print(context)" > /tmp/argaze
+```
+
+* Pause context processing:
+
+```shell
+echo "context.pause()" > /tmp/argaze
+```
+
+* Resume context processing:
+
+```shell
+echo "context.resume()" > /tmp/argaze
+```
+
+## Edit
+
+Modify the content of JSON CONFIGURATION file with another JSON CHANGES file then, save the result into an OUTPUT file
+
+```shell
+python -m argaze edit CONFIGURATION CHANGES OUTPUT
+```
