+# cvat-ui module
+
+## Description
+This is a client UI for Computer Vision Annotation Tool based on React, Redux and Antd
+
+## Versioning
+If you make changes in this package, please do following:
+
+- After not important changes (typos, bug fixes, refactoring) do: ``npm version patch``
+- After adding new features do: ``npm version minor``
+- After significant UI redesign do: ``npm version major``
+
+Important: If you have changed versions for ``cvat-core``, ``cvat-canvas``, ``cvat-data``, 
+you also need to do ``npm install`` to update ``package-lock.json``
+
+## Commands
+- Installing dependencies:
+
+```bash
+cd ../cvat-core && npm install && cd - && npm install
+```
+
+- Running development UI server with autorebuild on change
+
+```bash
+npm start
+```
+
+- Building the module from sources in the ```dist``` directory:
+
+```bash
+npm run build
+npm run build -- --mode=development     # without a minification
+```
+
+Important: You also have to run CVAT REST API server (please read ``CONTRIBUTING.md``)
+to correct working since UI gets all necessary data (tasks, users, annotations) from there
