-# How to contribute to Computer Vision Annotation Tool (CVAT)
+# Contributing to this project
 
-When contributing to this repository, please first discuss the change you wish to make via issue,
-email, or any other method with the owners of this repository before making a change.
+Please take a moment to review this document in order to make the contribution
+process easy and effective for everyone involved.
+
+Following these guidelines helps to communicate that you respect the time of
+the developers managing and developing this open source project. In return,
+they should reciprocate that respect in addressing your issue or assessing
+patches and features.
+
+## Branching model
+
+The project uses [a successful Git branching model](https://nvie.com/posts/a-successful-git-branching-model).
+Thus it has a couple of branches. Some of them are described below:
+
+- `origin/master` to be the main branch where the source code of
+HEAD always reflects a production-ready state.
+- `origin/develop` to be the main branch where the source code of
+HEAD always reflects a state with the latest delivered development
+changes for the next release. Some would call this the “integration branch”.
+
+## Using the issue tracker
+
+The issue tracker is the preferred channel for [bug reports](#bugs),
+[features requests](#features) and [submitting pull
+requests](#pull-requests), but please respect the following restrictions:
+
+* Please **do not** use the issue tracker for personal support requests (use
+  [Stack Overflow](http://stackoverflow.com)).
+
+* Please **do not** derail or troll issues. Keep the discussion on topic and
+  respect the opinions of others.
+
+  <a name="bugs"></a>
+## Bug reports
+
+A bug is a _demonstrable problem_ that is caused by the code in the repository.
+Good bug reports are extremely helpful - thank you!
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** &mdash; check if the issue has already been
+   reported.
+
+2. **Check if the issue has been fixed** &mdash; try to reproduce it using the
+   latest `develop` branch in the repository.
+
+3. **Isolate the problem** &mdash; ideally create a reduced test case.
+
+A good bug report shouldn't leave others needing to chase you up for more
+information. Please try to be as detailed as possible in your report. What is
+your environment? What steps will reproduce the issue? What browser(s) and OS
+experience the problem? What would you expect to be the outcome? All these
+details will help people to fix any potential bugs.
+
+Example:
+
+> Short and descriptive example bug report title
+>
+> A summary of the issue and the browser/OS environment in which it occurs. If
+> suitable, include the steps required to reproduce the bug.
+>
+> 1. This is the first step
+> 2. This is the second step
+> 3. Further steps, etc.
+>
+>
+> Any other information you want to share that is relevant to the issue being
+> reported. This might include the lines of code that you have identified as
+> causing the bug, and potential solutions (and your opinions on their
+> merits).

+## Feature requests
+
+Feature requests are welcome. But take a moment to find out whether your idea
+fits with the scope and aims of the project. It's up to *you* to make a strong
+case to convince the project's developers of the merits of this feature. Please
+provide as much detail and context as possible.
+
+<a name="pull-requests"></a>
+## Pull requests
+
+Good pull requests - patches, improvements, new features - are a fantastic
+help. They should remain focused in scope and avoid containing unrelated
+commits.
+
+**Please ask first** before embarking on any significant pull request (e.g.
+implementing features, refactoring code, porting to a different language),
+otherwise you risk spending a lot of time working on something that the
+project's developers might not want to merge into the project.
+
+Please adhere to the coding conventions used throughout a project (indentation,
+accurate comments, etc.) and any other requirements (such as test coverage).
+
+Follow this process if you'd like your work considered for inclusion in the
+project:
+
+1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
+   and configure the remotes:
+
+   ```bash
+   # Clone your fork of the repo into the current directory
+   git clone https://github.com/<your-username>/<repo-name>
+   # Navigate to the newly cloned directory
+   cd <repo-name>
+   # Assign the original repo to a remote called "upstream"
+   git remote add upstream https://github.com/<upstream-owner>/<repo-name>
+   ```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+   ```bash
+   git checkout <dev-branch>
+   git pull upstream <dev-branch>
+   ```
+
+3. Create a new topic branch (off the main project development branch) to
+   contain your feature, change, or fix:
+
+   ```bash
+   git checkout -b <topic-branch-name>
+   ```
+
+4. Commit your changes in logical chunks. Please adhere to these [git commit
+   message guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+   or your code is unlikely be merged into the main project. Use Git's
+   [interactive rebase](https://help.github.com/articles/interactive-rebase)
+   feature to tidy up your commits before making them public.
+
+5. Locally merge (or rebase) the upstream development branch into your topic branch:
+
+   ```bash
+   git pull [--rebase] upstream <dev-branch>
+   ```
+
+6. Push your topic branch up to your fork:
+
+   ```bash
+   git push origin <topic-branch-name>
+   ```
+
+7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
+    with a clear title and description.
+
+**IMPORTANT**: By submitting a patch, you agree to allow the project owner to
+license your work under the same license as that used by the project.

 # Computer Vision Annotation Tool (CVAT)
 
+[![Gitter chat](https://badges.gitter.im/opencv-cvat/gitter.png)](https://gitter.im/opencv-cvat)
+
 CVAT is completely re-designed and re-implemented version of [Video Annotation Tool from Irvine, California](http://carlvondrick.com/vatic/) tool. It is free, online, interactive video and image annotation tool for computer vision. It is being used by our team to annotate million of objects with different properties. Many UI and UX decisions are based on feedbacks from professional data annotation team.

+### AWS-Deployment Guide
+
+There are two ways of deploying the CVAT.
+1. **On Nvidia GPU Machine:** Tensorflow annotation feature is dependent on GPU hardware. One of the easy ways to launch CVAT with the tf-annotation app is to use AWS P3 instances, which provides the NVIDIA GPU. Read more about [P3 instances here.](https://aws.amazon.com/about-aws/whats-new/2017/10/introducing-amazon-ec2-p3-instances/)
+Overall setup instruction is explained in [main readme file](https://github.com/opencv/cvat/), except Installing Nvidia drivers.  So we need to download the drivers and install it. For Amazon P3 instances, download the Nvidia Drivers from Nvidia website. For more check [Installing the NVIDIA Driver on Linux Instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-nvidia-driver.html) link.
+
+2. **On Any other AWS Machine:** We can follow the same instruction guide mentioned in the [Readme file](https://github.com/opencv/cvat/). The additional step is to add a [security group and rule  to allow  incoming connections](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html).
+
+For any of above, don't forget to add exposed AWS public IP address to `docker-compose.override.com`.
