-### Getting started
+## Getting started
-#### Installation
+
+### Requirements
+- `docker-compose` in version `1.25.0`
+- `docker` in version `20.10.7`
+
+### Installation
 ```bash
 git clone https://github.com/miloszowi/everyone-mention-telegram-bot.git
-pip install -r requirements.txt
-python entrypoint.py
 ```
-
+after that, you need to copy env files and fulfill it with correct values
-#### Requirements
-- `python` with version specified in `runtime.txt`
-- `pip` with version `20.0.2`
-
-#### Env files
-First, copy env files for database and app containers
 ```bash
-cp docker/config/app/app.dist.env docker/config/app/app.env
+cp docker/config/app.dist.env docker/config/app.env
-cp docker/config/database/database.dist.env docker/config/app/app.env
+cp docker/config/database.dist.env docker/config/app.env
 ```
-and then fulfill copied `.env` files with required values
+and finally, you can run the bot by launching docker containers
-
+```bash
+docker-compose up -d
+```
+(`-d` flag will run containers in detached mode)
+### Logs
+You can use
+```bash
+docker/logs <container>
+```
+to check container logs
+### Env files
 app.env
-- `bot_token` - your telegram bot token from [BotFather](https://telegram.me/BotFather)
+- `BOT_TOKEN` - your telegram bot token from [BotFather](https://telegram.me/BotFather)
 - `MONGODB_DATABASE` - MongoDB database name
 - `MONGODB_USERNAME` - MongoDB username
 - `MONGODB_PASSWORD` - MongoDB password
 - `MONGODB_HOSTNAME` - MongoDB host (default `database` - container name)
-- `MONGODB_PORT` - MongoDB port (default `port` - given in docker-compose configuration)
+- `MONGODB_PORT` - MongoDB port (default `27017` - given in docker-compose configuration)
 
 database.env
 - `MONGO_INITDB_ROOT_USERNAME` - conf from `app.env`
 - `MONGO_INITDB_ROOT_PASSWORD` - conf from `app.env`
