+# Config for multi-device knowledge distillation in knowledge_distillation_distributed.py
+# using a teacher and student model
+#
+# This config assumes that you've ran the following commands before launching KD:
+# First download the student and teacher models
+#   tune download Qwen/Qwen2-0.5B-Instruct --output-dir /tmp/Qwen2-0.5B-Instruct --ignore-patterns None
+#   tune download Qwen/Qwen2-1.5B-Instruct --output-dir /tmp/Qwen2-1.5B-Instruct --ignore-patterns None
+#
+# You get better results using KD if the teacher model has already been fine-tuned on the target dataset:
+#   tune run --nnodes 1 --nproc_per_node 2 lora_finetune_distributed --config qwen2/1.5B_lora
+#
+# To launch on a single device, run the following command from root:
+#   tune run --nnodes 1 --nproc_per_node 2 knowledge_distillation_distributed --config qwen2/knowledge_distillation_distributed
+#
+# This config works only for distilling on a single device.
