- A CLI to preprocess and DB push for Zele project.
+# Zele-Utils
+A CLI tool for preprocessing and pushing data to the database for the Zele project.
+
+## Installation
+1. Install Anaconda or Miniconda.
+2. Create the environment and install required packages:
+   ```bash
+   conda env create -f environment.yml
+   ```
+3. Activate the environment:
+   ```bash
+   conda activate zele-utils
+   ```
+4. Set up your `.env` file using `.example.env` as a template.
+
+## Usage
+Place the file you want to process in `/data/` and push to the database in the appropriate directory. Run the corresponding command. For a list of available commands and options, use:
+   ```bash
+   python main.py --help
+   ```
+## Features
+1. Processes MATSim's `Population.xml` and `Network.xml` files.
+2. Processes data from the Overpass API and `map.osm` file.
