Documetation missing for how to activate OCR (tesseract)

Nobody has claimed this yet.

I really want to try out OCR but every time I run a test using the Get Text keyword, I get the following error message:

[error] text: text recognition is currently switched off

I am stuck pointing robotframework-SikuliLibrary to sikuli with OCR enabled. I think it is because robotframework-SikuliLibrary does not use the Sikuli jar files I have installed on my system.

Any advice for how to enable text recognition?

So far I have
* downloaded the latest version of robotframework-SikuliLibrary from github
* mvn package
* python setup.py install
* Installed sikulix from http://sikulix.com/ and selected the Tesseract option
* run SikuliIDE and enabled OCR in the options
* confirmed that OCR works in SikuliIDE using a simple script containing just 'click ("sometext")'

Start with the Get Text keyword and the installation steps in the issue, including mvn package, python setup.py install, and SikuliIDE's OCR setting. Trace how this installation differs from the SikuliIDE setup, then document the required OCR activation and configuration steps so a user can reproduce the working setup outside SikuliIDE.
