+# Doc on VLM training
+
+## Installation
+
+Required packages are mostly the same as for LLMs. Need to install PIL package to work with images: `pip install pillow`.
+
+Some HF-related scripts may also require `pip install accelerate`.
+
+`hf_transfer` may be installed to speed-up downloads from HF.
+
+All scripts also use [Idefics3 processor](https://huggingface.co/docs/transformers/en/model_doc/idefics3#transformers.Idefics3Processor) instead of tokenizer. By default it is expected to be saved in `hf_idefics3_processor` folder.
+
+## Overview
+
+VLM functionality uses [Idefics3](https://arxiv.org/pdf/2408.12637) architecture. It combines a CLIP-style model with a Llama-style model using their pixel shuffling technique. 
+
+[`models/idefics.py`](/src/nanotron/models/idefics.py) contains code of the VLM implementation.
+
+[`tools/idefics`](/tools/idefics3/) contains HF/Nanotron conversion and simple evaluation scripts.
+
+[`examples/vqa`](/examples/vqa/) contains a simple fine-tuning example using a small dataset that fits into RAM.
+
+[`example/caption-pretrain`](/examples/caption-pretrain/) contains code that runs pretraining on a preprocessed/raw captioning dataset (LAION).
+
+Training dataloader uses `datasets.IterableDataset` to load and preprocess the dataset step-by-step. It allows having different encoders for different datasets and is inspired by Megatron-Energon dataloader. Each dataset requires a sample encoder, that processes single samples, and a batch encoder that collates and encodes batches. 
+
+> Current sample encoder just appends the \<image\> token to the caption. Need to check whether it is enough or we should use the full prompt template like in [`tools/idefics/loss_on_captions_hf.py`](/tools/idefics3/loss_on_captions_hf.py) 
+
+Dataloader code is present in [`modular_dataloader`](/src/nanotron/modular_dataloader/), and your custom encoders can be added there. Currently dataloader only supports datasets stored in parquet.
