-# LLaVA-Med model for multimodal radiology report generation
+# LLaVA-Med model for multimodal radiology report generation
+
+This is a model based on LLaVA-Med 1.0, finetuned to generate medical reports, based on a chest X-ray and a prompt, 
+in our case, the instruction was "write the finding section of chest x-ray radiology report".
+
+The dataset used for finetuning was the MIMIC-CXR  share for the challenge in Radiology Report Generation 
+for the Association for Computational Linguistics 2024 at BioNLP Workshop 
+
+We used the 148,374 findings of MIMIC-CXR for finetuing during 3 epochs. 
+
+More details of the challenge can be found on the [challenge web page](https://stanford-aimi.github.io/RRG24/)
+or in [workshop site](https://aclweb.org/aclwiki/BioNLP_Workshop)
