This topic assumes you have already installed DITA Open Toolkit and its prerequisite products, and have verified your installation, as described in the installation chapter of this document.
Note: In our experience, DocBook support by the DITA Open Toolkit can sometimes be problematic. According to IBM, "there is no guarantee of fault-free transforms."
In general, the instructions in this topic assume the Windows environment; the procedure is very similar in other operating system environments.
