 Service is built with Python, FastAPI and is using Redis for data storage.
 
+## Installation
+
+### Requirements
+
+- Python 3.11+
+- Redis
+- Python development libraries (optional, only needed for `hiredis` module installation)
+
+### How to install
+
+#### TL/DR
+
+```bash
+$ git clone git@git.ivnglkv.ru:ivnglkv/rectes.git
+$ python3 -m venv venv
+$ . ./venv/bin/activate
+$ pip install .
+```
+
+---
+
+Steps to install Rectes:
+
+1. Clone repository
+2. (optional) Create virtual environment
+3. Install package
+
+### Running Rectes server
+
+After installation is done, you can start rectes with `rectes` command.
+The web server will be started with `uvicorn` ASGI web server.
+
+```bash
+$ rectes
+```
+
+### Configuration
+
+Configuration is done through config file. By default, path is `/etc/rectes/rectes.toml`.
+You can override this by setting environment variable `RECTES_CONF_FILE` value to actual file
+location, i.e.:
+
+```bash
+$ RECTES_CONF_FILE=/home/user/.conf/rectes.toml rectes
+```
+
+You can find all available configuration options in the example file, located
+at [conf/rectes.toml.example](conf/rectes.toml.example) under Git root.
