+Scritp the context
+==================
+
+Context objects are accessible from a Python script.
+
+## Load configuration from JSON file
+
+A context configuration can be loaded from a JSON file using the [*load*](../../../argaze.md/#argaze.load) function.
+
+```python
+from argaze import load
+
+# Load a context
+with load(configuration_filepath) as context:
+
+    while context.is_running():
+
+        # Do something with context
+        ...
+
+        # Wait some time eventually
+        ...
+```
+
+!!! note
+    The **with** statement enables context by calling its **enter** method then ensures that its **exit** method is always called at the end.
+
+## Load configuration from dictionary
+
+A context configuration can be loaded from a Python dictionary using the [*from_dict*](../../../argaze.md/#argaze.DataFeatures.from_dict) function.
+
+```python
+from argaze import DataFeatures
+
+import my_package
+
+# Set working directory to enable relative file path loading 
+DataFeatures.set_working_directory('path/to/folder')
+
+# Edit a dict with context configuration
+configuration = {
+    "name": "My context",
+    "parameter": ...,
+    "pipeline": ...
+}
+
+# Load a context from a package
+with DataFeatures.from_dict(my_package.MyContext, configuration) as context:
+
+    while context.is_running():
+
+        # Do something with context
+        ...
+
+        # Wait some time eventually
+        ...
+```
+
+## Manage context
+
+Check the context or the pipeline type to adapt features.
+
+```python
+from argaze import ArFeatures
+
+# Assuming the context is loaded and is running
+...
+
+    # Check context type
+
+    # Live processing case: calibration method is available
+    if issubclass(type(context), ArFeatures.LiveProcessingContext):
+        ...
+
+    # Post processing case: more playback methods are available
+    if issubclass(type(context), ArFeatures.PostProcessingContext):
+        ...
+
+    # Check pipeline type
+
+    # Screen-based case: only gaze positions are processes
+    if issubclass(type(context.pipeline), ArFeatures.ArFrame):
+        ...
+
+    # Head-mounted case: camera images also processes
+    if issubclass(type(context.pipeline), ArFeatures.ArCamera):
+        ...
+```
+
+## Display context
+
+The context image can be displayed in low priority to not block pipeline processing.
+
+```python
+# Assuming the context is loaded and is running
+...
+
+    # Display context if the pipeline is available
+    try:
+
+        ... = context.image(wait = False)
+
+    except DataFeatures.SharedObjectBusy:
+
+        pass
+```
