+
+The LLM Rubric Auto-grader
+==========================
+
+The **LLM Rubric Autograde** assessment automatically grades student submissions using an LLM-generated rubric and displays feedback directly to students without requiring instructor approval.
+
+It can be found in the **Auto-Graded** section of the assessments menu. If you wish to approve the LLM grading before it is displayed to the student, see the :ref:`LLM Rubric <llm-based-rubric>` assessment in the **Manually Graded** section.
+
+More information about adding assessments can be found in our :ref:`assessment documentation <add-assessment>`.
+
+There are two steps to the **LLM Rubric Autograde** process:
+
+1. Rubric generation
+2. LLM-based grading using the generated rubric
+
+
+Add an **LLM Rubric Autograde** assessment to your guide page and follow the steps below.
+

+- Contents of the provided solution file
+- The Course, Module, and Assignment name
