+# How to contribute
+
+Bug-fixes and features often come from users of the MPAndroidChart library and improve it greatly. We want to keep it as easy as possible to contribute changes that improve the experience for users all around the world. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
+
+## Creating Issues
+
+There are two main issue templates, one for bugs and another for feature requests. Please use them! You're issue will be much easier to understand, and bugs easier to fix, if you follow the templates. If your issue doesn't fit into those, just use the generic template.
+
+Search existing [issues] to see if your bug has already been reported or if a feature request already exists. Don't forget to remove `is:open` so you see all the issues! If you find that one already exists, use reactions to show how much you care!
+
+## Making Pull Requests
+
+Careful! If you fail to follow these guidlines, you're pull request may be closed, *even if it's really awesome*. 
+
+  0. **Search** open [pull requests] AND existing [issues] to make sure what you want to do isn't already being worked on or already has an open pull request.
+  1. **Fork** the repository
+  1. **Create** a new branch based on `master`, and name it according to your changes
+  1. **Add** your commits, they MUST follow the [Commit Style](#commit-style) below
+  1. **Test** your changes by actually running the example app, or create a new example
+  1. **Create** a pull request, following the auto-generated template
+  1. ???
+  1. Profit :money_with_wings:
+  
+You are encouraged to use [GitHub Desktop] to inspect your code changes before committing them. It can reveal small changes that might have gone unnoticed, and would be requested for removal before merging.
+
+Check out [#3975](https://github.com/PhilJay/MPAndroidChart/pull/3975) for an example of a good-made-better pull request.
+
+## Commit Style
+
+  * **Make commits of logical units**  
+  Don't load your commits with tons of changes, this makes it hard to follow what is happening. However, if you have done a lot of work, and there are commits and merges all over the place, squash them down into fewer commits.
+  
+  * **Conform to the code style**  
+  It's easy, just look around!
+  
+  * **Write good commit messages**  
+  You may prefer [Tim Pope's style], you might like the [commitizen-friendly] way. Regardless of the color you pick, you MUST stay within the lines!  
+  ```
+The commit title CANNOT exceed 50 characters
+
+The body of the message comes after an empty new line, and describes the
+changes more thoroughly. If the change is obvious and self-explanatory
+from the title, you can omit the body. You should describe all changes
+if many were made, or maybe some trickery that only code wizards can
+understand.
+
+Be polite and wrap your lines to 72 characters, but if you prefer going
+to 100 characters then I guess we can't stop you.
+```
+

+Thanks for reading the contributing file! Have some cake! :cake:

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
