+**E2E (API) Python Based Test Scripting Guide**
+
+
+**Preparation**
+
+After getting Harbor source code (git clone https://github.com/goharbor/harbor.git), Harbor E2E API  test scripts  can be found in tests/apitests/python directory.
+
+Before scripting, please make sure swagger client has been made by "make swagger_client", then archive "harborclient" will be made
+
+1. `git clone https://github.com/goharbor/harbor.git`
+
+2. `cd harbor`
+
+3. `make swagger_client`
+
+4. `cd harborclient/`
+
+
+We use $HARBORCLIENT_PATH represent the path of "harborclient" you've made by "make swagger_client".
+
+Deploy Harbor instance for testing, and we will use $HARBOR_URL to represent the deployed Harbor in this document.
+
+Harbor E2E API test scripts will import python library under archive "harborclient", please set OS environment variant for Harbor E2E API test scripts:
+
+
+1. `export HARBOR_HOST=$HARBOR_URL`
+2. `export SWAGGER_CLIENT_PATH=$HARBORCLIENT_PATH`
+
+Until now, we have all preparation work done.
+
+**Scripting**
+
+As you can see, we will use python library made by "make swagger_client", in this library, we have all API functions and models, but for more convenience we encapsulate one more level in archive "library", so the script structure is as bellow:
+
+	-library/
+
+	-test_project_level_policy_content_trust.py
+
+	-test_project_quota.py
+
+	-test_retention.py
+
+	-...
+
+You can add both library code and script code, since not all APIs have been encapsulated.
+
+
+**Execution Example**
+
+root@harbor:/harbor/code/harbor# `python ./tests/apitests/python/test_add_sys_label_to_tag.py`
