 ## Features
 
-sinqMotor offers a variety of additional methods for children classes to standardize certain patterns (e.g. writing messages to the IOC shell and the motor message PV). For a detailed description, please see the respective function documentation in the .h-file. All of these functions can be overwritten manually if e.g. a completely different implementation of `poll` is required

 The versioning is done via git tags. Git tags are recognized by the PSI build system: If you tag a version as 1.0, it will be built into the directory /ioc/modules/sinqMotor/1.0. The tag is directly coupled to a commit so that it is always clear which source code was used to build which binary.
 
-All existing tags can be listed with `git tag` in the sinqMotor directory. Detailed information (author, data, commit number, commit message) regarding a specific tag can be shown with `git show X.X`, where X.X is the name of your version. To create a new tag, use `git tag -a X.X`.
