+3. Download the [latest release](https://git.end-play.xyz/HoloUA/Discord/releases/latest)'s archive
+4. Extract the archive
+5. Navigate to the extracted folder and subfolder `Discord` in it
+6. Create a virtual environment:  
+   `python -m venv .venv` or `virtualenv .venv`
+7. Activate the virtual environment:  
+   Windows: `.venv\Scripts\activate.bat`  
+   Linux/macOS: `.venv/bin/activate`
+8. Install the dependencies:  
+   `python -m pip install -r requirements.txt`

+
+## Caching
+
+Although general database access speed is fast, caching might become helpful for
+bigger servers with many bot interactions. Currently, Redis and Memcached are supported.
+
+Configuration happens through the config key `caching`.
+
+Set `caching.type` to the service of you choice ("redis" or "memcached") and then update
+the URI to access the service. It's Redis' default URI format for Redis and "address:port"
+for Memcached.
+
+Which one should I choose?
+
+| Service   | Read/write speed | Config flexibility |
+|-----------|------------------|--------------------|  
+| Redis     | High             | Very flexible      |
+| Memcached | Very high        | Basic              |
+
+> Performance difference between Redis and Memcached is generally quite low, so your setup
+> should normally depend more on the configuration flexibility than on raw speed.
+
+## Debugging
+
+There's a config key `debug` that can be set to `true` for debugging purposes.
+
+It should be set to `false` in production, otherwise log becomes very verbose and might
+contain data that shouldn't normally be logged.
+
+## Docker [Experimental]
+
+As an experiment, Docker deployment option has been added.
+
+### Building the image
+
+1. `git clone https://git.end-play.xyz/HoloUA/Discord.git`
+2. `cd Discord`
+3. `docker build -t holoua-discord .`
+
+### Starting the bot
+
+1. Install MongoDB using the [official installation manual](https://www.mongodb.com/docs/manual/installation)
+2. Download
+   the [configuration example file](https://git.end-play.xyz/HoloUA/Discord/src/branch/main/config_example.json) and
+   store it somewhere you would like your bot to access it
+3. Complete the [configuration](#Configuration) step for this file
+4. `docker run -d -v /path/to/config.json:/app/config.json holoua-discord`
