+# Evaluation examples
+
+Here we put the data examples to benchmark the ability of agents when interacting with GUI.
+The examples are stored in `./examples` where each data item formatted as:
+
+```
+{
+    "id": "uid", # unique id
+    "snapshot": "snapshot_id", # the snapshot id of the environment, with some data already there and apps already opened, or just desktop
+    "instruction": "natural_language_instruction", # the natural language instruction of the task, what we want the agent to do
+    "source": "website_url", # where we know this example, some forum, or some website, or some paper
+    "config": {xxx}, # the scripts to setup the donwload and open files actions, as the initial state of a task
+    "trajectory": "trajectory_directory", # the trajectory directory, which contains the action sequence file, the screenshots and the recording video
+    "related_apps": ["app1", "app2", ...], # the related apps, which are opened during the task
+    "evaluator": "evaluation_dir", # the directory of the evaluator, which contains the evaluation script for this example
+…
+}
+```
+
+The `./trajectories` file contains the annotated trajectories for each data item in `./examples` for finishing the task.
+
+For now, it is under construction, and only tested on Windows 10. Please:
+- Modify the path accordingly to run the evaluation;
+- Remind us if some parts are overfit to our environment.
