I have very simple sentence, however I have 3 problems with it. The major one is whether I should you Past Simple or Present Perfect when saying that something was/has been generated. The Second one is whether I should use this or that, and the third one is whether I should use by or with. The sentence is as follows:
This/That documentation was/has been automatically generated by/with XYZ tool.
Maybe it is worth to mention, that this sentence is placed in the generated documentation itself.
