 # Python Semantic Matching Service
 
-This is a proof-of-concept implementation of a semantic matching service
-using Python. 
+This is a proof-of-concept implementation of a semantic matching service using Python. 
+The idea behind this service is to create a uniform interface for exchanging semantic matches, that are stored
+decentralized across multiple semantic matching services. 
 
-## Docker
+> [!warning]
+> This project is **not** about finding semantic matches or semantic similarities, it rather requires these as input.
 
+## Structure
+The project is structured as follows:
+- `algorithm.py` implements the decentralized match aggregation algorithm
+- `service.py` offers the service implementation using the [FastAPI](https://fastapi.tiangolo.com/) framework.
+  Note that you can find a detailed interface description (OpenAPI) by [running](#how-to-use) the server locally and 
+  navigating to `<endpoint>/docs`.
+
+## How to Use
+There are two main options to run:
+
+### Run `service.py`
+You need a working Python installation (3.11 or higher).
+- Clone this repository
+- Create a new virtual environment: `python3 -m venv venv` (Note that the service is only tested on Linux systems)
+- Activate the virtual environment: `source venv/bin/activate`
+- Install the package: `pip install .`
+- Copy the `config.ini.default` to `config.ini` and adapt the fields as necessary
+- Run the service: `python3 semantic_matcher/service.py`
+
+### Run via Docker
+To run via docker, you obviously need a working docker installation.
+- Clone the repository
+- Copy the `config.ini.default` to `config.ini` and adapt the fields as necessary
+- Choose one of the two options below:
+
+**Option 1:** Build and run manually
+
+In the project root directory:
 ```commandline
 docker build -t semantic_matching_service .
 ```
 ```commandline
 docker run -d -p 8000:8000 semantic_matching_service
 ```
+
+> [!note]
+> You may have to change the port in the run command if you changed it in your `config.ini`. 
+
+**Option 2:** Use the docker compose file
+
+In the project root directory:
+```commandline
+docker compose up
+```
+
+> [!note]
+> If you changed your `config.ini`, you might need to adapt the respective fields in the `compose.yaml`.
