-This repository contains a basic rest api for clamav which allows sites to scan files as they are uploaded
+This is two in one docker image so it runs open source virus scanner ClamAV (https://www.clamav.net/), automatic virus definition updates as background process and REST api interface to interact with ClamAV process.
 
-!! Project needs cleenup, Makefile and documentation doesn't match current status !!
+Travis CI build will build new release on weekly basis and push those to Docker hub [ClamAV-rest docker image](https://hub.docker.com/r/niilo/clamav-rest/). Virus definitions will be updated on every docker build.
