 ## Установка:
-+ Скачать и распаковать набор скриптов, например в `/home/$USER/.vk0nline`
-+ Создать директорию для юнитов systemd: `mkdir -p ~/.config/systemd/user` 
-и перейти в неё: `cd ~/.config/systemd/user`
-+ Сделать символические ссылки на сервис и таймер:
-```
-ln -s /home/user_name/.vk0nline/systemd/user/vk0nline.service .
-ln -s /home/user_name/.vk0nline/systemd/user/vk0nline.timer .
-```
-+ Изменить настройки скрипта и сделать его исполняемым:
-```
-cd ~/.vk0nline/
-mv config.json.example config.json
-chmod 755 ./vk0nline.py
-edit config.json
-```
-+ Прописать полный путь к файлу конфигурации в скрипте:
