+Usage:
+
+This is a vision capable model. It can be used together with its multimedia projector layers to process images and text inputs
+and generate text outputs. The mmproj file is made available in this repository. To test vision mode follow the docs in the mtmd
+readme in the tools directory of the source tree https://github.com/ggml-org/llama.cpp/blob/master/tools/mtmd/README.md . 
+Use of the best available model (Q4_K_H) is recommended to maximize the accuracy of vision mode.  To run it on a 12G VRAM
+GPU use --ngl 32.  Generation speed is still quite good with partial offload.
