 ## Setup
+Make sure that your host system has at least one WireGuard interface (for example wg0) available.
+If you did not start up a WireGuard interface yet, take a look at [wg-quick](https://manpages.debian.org/unstable/wireguard-tools/wg-quick.8.en.html) in order to get started.

 A detailed description for using this software with a raspberry pi can be found in the [README-RASPBERRYPI.md](README-RASPBERRYPI.md).
 
-## What is out of scope
+## Configuration
+You can configure WireGuard Portal using either environment variables or a yaml configuration file.
+The filepath of the yaml configuration file defaults to **config.yml** in the working directory of the executable.
+It is possible to override the configuration filepath using the environment variable **CONFIG_FILE**.
+For example: `CONFIG_FILE=/home/test/config.yml ./wg-portal-amd64`.
 
- * Generation or application of any `iptables` or `nftables` rules
- * Setting up or changing IP-addresses of the WireGuard interface on operating systems other than linux

+### RESTful API
+WireGuard Portal offers a RESTful API to interact with.
+The API is documented using OpenAPI 2.0, the Swagger UI can be found
+under the URL `http://<your wg-portal ip/domain>/swagger/index.html?displayOperationId=true`.
+
+The [API's unittesting](tests/test_API.py) may serve as an example how to make use of the API with python3 & pyswagger.
+
+## What is out of scope
+ * Creating or removing WireGuard (wgX) interfaces.
+ * Generation or application of any `iptables` or `nftables` rules.
+ * Setting up or changing IP-addresses of the WireGuard interface on operating systems other than linux.
+ * Importing private keys of an existing WireGuard setup.

+# pyswagger unittests for the API & UI
+
+## Requirements
+
+```
+wg-quick up conf/wg-example0.conf
+sudo LOG_LEVEL=debug CONFIG_FILE=conf/config.yml ../dist/wg-portal-amd64 
+
+python3 -m venv ~/venv/apitest
+~/venv/apitest/bin/pip install pyswagger mechanize requests pytest PyYAML
+```
+
+## Running
+
+### API
+```
+~/venv/apitest/bin/python3 -m unittest test_API.TestAPI 
+```
+
+### UI
+```
+~/venv/lsl/bin/pytest pytest_UI.py 
+```
+
+
+## Debugging
+Debugging for requests http request/response is included for the API unittesting.
+To use, adjust the log level for "api" logger to DEBUG
+
+```python
+log.setLevel(logging.DEBUG)
+<action>
+log.setLevel(logging.INFO)
+```
+This will provide:
+```
