   Before calling `doPoll`:
   - Try to execute `atFirstPoll` once (and retry, if that failed)

   After calling `doPoll`:
   - Reset `motorStatusProblem_`, `motorStatusCommsError_` and `motorMessageText_` if `doPoll` returned `asynSuccess`
   - Run `callParamCallbacks`
   - Return the status of `doPoll`
 - `doPoll`: This is an empty function which should be overwritten by concrete driver implementations.
 
+## Versioning
+
+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`.

 ## How to build it
 
-The makefile in the top directory includes all necessary steps for compiling a shared library together with the header files into `/ioc/modules` (using the PSI EPICS build system).Therefore it is sufficient to run `make install -f Makefile` from the terminal. If you want to compile a new version, adjust the entry `LIBVERSION` accordingly.

 To use the library when writing a concrete motor driver, include it in the makefile of your application /library the same way as other libraries such as e.g. `asynMotor` by adding `REQUIRED+=sinqMotor` to your Makefile.
