 ### How to compile with docker
 ```Shell
-docker build -t sequenceparser:centos6 .
-docker run -v <path to sequenceparser>:/opt/sequenceparser sequenceparser:centos6 /opt/sequenceparser/docker/centos6/build.sh
+docker build -t sequenceparser:centos7 .
+docker run -v <path to sequenceparser>:/opt/sequenceparser sequenceparser:centos7 /opt/sequenceparser/tools/docker/centos7/build.sh
 ```
 The compiled libraries is installed into centos6 folder at root folder of sequenceparser repository
