 # TG2PDF
 This telegram bot converts any libreoffice-supported document into a pdf file.
-It uses [pyrogram](https://docs.pyrogram.org/), [libreoffice](https://libreoffice.org) and optionally [unoserver](https://github.com/unoconv/unoserver).
-The unoserver dependency is entirely optional - however it improves theoretical processing speed, so its included into Dockerfile by default.
+It uses [pyrogram](https://docs.pyrogram.org/), [libreoffice](https://libreoffice.org) and [unoserver](https://github.com/unoconv/unoserver).
