The document provides instructions for finding and posting in the discussion board on an online course platform. It explains that the discussion board can be found on the left side under the green tab. To post, students click on the discussion board link and create an original thread with their comments before submitting. They are then asked to respond to two classmates' posts as well. A rubric for grading discussion board posts can be found under the Course Information tab, outlining how in-depth posts should be and how the instructor will assess them.
