+# Web Tests
+Web tests are selenium-based browser interaction tests, that fully simulate
+actual user's behaviours.
+
+# Preparation
+- Have Google Chrome (Any version) installed.
+- Install following python packages with `pip`:
+    - `selenium`
+    - `webdriver-manager`
+
+# Run Tests
+- Have WebUI with ControlNet installed running on `localhost:7860`
+- Run `python main.py --overwrite_expectation` for the first run to set a 
+baseline.
+- Run `python main.py` later to verify the baseline still holds.
