Hello, this extension and the tools it offers are amazing. However the installation documentation is not enough detailed for private wikis administrators, quite often not advanced users, able to work on server configuration etc.. E.g. the guide provided here for the ocr tool should be improved with the specification of the apache and php directives to change, and possible issues that could come up during installation.
Hope someone could improve the documentation! I am available to translate it and collaborate but I don't have skills to write it down.
