 :ref:`Prerequisite Obtaining a Pre-Trained Model <prerequisite>`
    This section provides instructions on how to download pre-trained LLMs in .nemo format. The following section will use these base LLMs for further fine-tuning and alignment. 
 
+:ref:`Model Alignment by REINFORCE <nemo-aligner-reinforce>`
+   In this tutorial, we will guide you through the process of aligning a NeMo Framework model using REINFORCE. This method can be applied to various models, including LLaMa2 and Mistral, with our scripts functioning consistently across different models.

 :ref:`Model Alignment by Supervised Fine-Tuning (SFT) <nemo-aligner-sft>`
    In this section, we walk you through the most straightforward alignment method. We use a supervised dataset in the prompt-response pairs format to fine-tune the base model according to the desired behavior.
