+You Only Show Once
+==================
+
+YOSO is a GUI application providing a means of creating training data set for
+`YOLO <http://pjreddie.com/darknet/yolo/>`_, a state-of-the-art, real-time object detection system.
+It can be useful for other computer vision systems, because I believe that YOLO's
+label file format is quite a good and flexible choice.
+
+
+Requirements
+============
+
+- Python 3
+- PyQt5
+
+
+Data Directory Structure
+========================
+
+YOSO should be pointed to a data directory having this structure:
+
+::
+
+ data
+ |\_ classes
+ | \_ "0 - roy.jpg"
+ | \_ "1 - poli.jpg"
+ | \_ ...
+ |\_ images
+ | |\_ poli
+ | | \_ poli-001.jpg
+ | | \_ ...
+ | | \_ poli-009.jpg
+ | | \_ ...
+ | |\_ roy
+ | | \_ roy-1.jpg
+ | | \_ ...
+ | | \_ roy-99.jpg
+ | | \_ ...
+ | \_ ...
+ \_ labels
+ |\_ poli
+ | \_ poli-001.jpg.txt
+ | \_ ...
+ | \_ poli-009.jpg.txt
+ | \_ ...
+ |\_ roy
+ | \_ roy-1.jpg.txt
+ | \_ ...
+ | \_ roy-99.jpg.txt
+ | \_ ...
+ \_ ...
+
+
+``data/classes`` must contain JPEG files describing object classes in format: ``<class number> - <short description>.jpg``
+
+``data/images`` has arbitrary structure and contains JPEG or PNG images (``*.jpg``, or ``*.jpeg``, ``*.png``).
+This is a training set of hundreds or thousands of images.
+
+``data/labels`` is managed by YOSO and has the same structure as ``data/images``.
+All missed subdirectories will be created automatically.
+Note that label files create by YOSO have different naming scheme, so you might have to update
+`Darknet <http://pjreddie.com/darknet>`_ sources.
+
+
+Controls
+========
+
+- To add a bounding box select a region with the mouse pointer.
+ Newly added bounding box will have object class currently selected
+ in the list on the right.
+
+- To delete a bounding box double click on it.
+
+- To change object class drag an item from the list on the right
+ and drop it into existing bounding box.
+
+Whenever a bounding box is added, deleted or changed, the result is automatically saved.
+
