+
+## Files ##
+./Questions
+- For v2.0, download the question files from the [VQA download page](http://www.visualqa.org/download.html), extract them and place in this folder.
+- For v1.0, both real and abstract, question files can be found on the [VQA v1 download page](http://www.visualqa.org/vqa_v1_download.html).

+- Question files from Beta v0.1 release (10k MSCOCO images, 30k questions, 300k answers) can be found [here](http://visualqa.org/data/mscoco/prev_rel/Beta_v0.1/Questions_Train_mscoco.zip).
+
+./Annotations
+- For v2.0, download the annotations files from the [VQA download page](http://www.visualqa.org/download.html), extract them and place in this folder.
+- For v1.0, for both real and abstract, annotation files can be found on the [VQA v1 download page](http://www.visualqa.org/vqa_v1_download.html).

+
+./Images
+- For real, create a directory with name mscoco inside this directory. For each of train, val and test, create directories with names train2014, val2014 and test2015 respectively inside mscoco directory, download respective images from [MS COCO website](http://mscoco.org/dataset/#download) and place them in respective folders.
+- For abstract, create a directory with name abstract_v002 inside this directory. For each of train, val and test, create directories with names train2015, val2015 and test2015 respectively inside abstract_v002 directory, download respective images from [VQA download page](http://www.visualqa.org/download.html) and place them in respective folders.
+
+./PythonHelperTools
+- This directory contains the Python API to read and visualize the VQA dataset
+- vqaDemo.py (demo script)
+- vqaTools (API to read and visualize data)
+
+./PythonEvaluationTools
+- This directory contains the Python evaluation code
+- vqaEvalDemo.py (evaluation demo script)
+- vqaEvaluation (evaluation code)
+
+./Results
+- OpenEnded_mscoco_train2014_fake_results.json (an example of a fake results file for v1.0 to run the demo)
+- Visit [VQA evaluation page] (http://visualqa.org/evaluation) for more details.
+
+./QuestionTypes
+- This directory contains the following lists of question types for both real and abstract questions (question types are unchanged from v1.0 to v2.0). In a list, if there are question types of length n+k and length n with the same first n words, then the question type of length n does not include questions that belong to the question type of length n+k.
