+## Downloading using huggingface-cli
+If you do not have hugginface-cli installed:
+```
+pip install -U "huggingface_hub[cli]"
+```
+Download the specific file you want:
+```
+huggingface-cli download legraphista/Qwen2-1.5B-IMat-GGUF --include "Qwen2-1.5B.Q8_0.gguf" --local-dir ./
+```
+If the model file is big, it has been split into multiple files. In order to download them all to a local folder, run:
+```
+huggingface-cli download legraphista/Qwen2-1.5B-IMat-GGUF --include "Qwen2-1.5B.Q8_0/*" --local-dir ./
+# see FAQ for merging GGUF's
+```
+

+
+## Inference
+
+### Simple chat template
+```
+<|im_start|>system
+You are a helpful assistant<|im_end|>
+<|im_start|>user
+{user_prompt}<|im_end|>
+<|im_start|>assistant
+{assistant_response}<|im_end|>
+<|im_start|>user
+{next_user_prompt}<|im_end|>
+
+```
+
+### Chat template with system prompt
+```
+<|im_start|>system
+{system_prompt}<|im_end|>
+<|im_start|>user
+{user_prompt}<|im_end|>
+<|im_start|>assistant
+{assistant_response}<|im_end|>
+<|im_start|>user
+{next_user_prompt}<|im_end|>
+
+```
+
+### Llama.cpp
+```
+llama.cpp/main -m Qwen2-1.5B.Q8_0.gguf --color -i -p "prompt here (according to the chat template)"
+```

+
+## FAQ
+
+### Why is the IMatrix not applied everywhere?
+According to [this investigation](https://www.reddit.com/r/LocalLLaMA/comments/1993iro/ggufs_quants_can_punch_above_their_weights_now/), it appears that lower quantizations are the only ones that benefit from the imatrix input (as per hellaswag results). 
+
+### How do I merge a split GGUF?
+1. Make sure you have `gguf-split` available
+    - To get hold of `gguf-split`, navigate to https://github.com/ggerganov/llama.cpp/releases
+    - Download the appropriate zip for your system from the latest release
+    - Unzip the archive and you should be able to find `gguf-split`
+2. Locate your GGUF chunks folder (ex: `Qwen2-1.5B.Q8_0`)
+3. Run `gguf-split --merge Qwen2-1.5B.Q8_0/Qwen2-1.5B.Q8_0-00001-of-XXXXX.gguf Qwen2-1.5B.Q8_0.gguf`
+    - Make sure to point `gguf-split` to the first chunk of the split.
