+# How to contribute?
+
+## Testing 
+
+Just use OpenTracks and tell us what can be improved by opening an issue [here](https://github.com/OpenTracksApp/OpenTracks/issues/new/choose)
+
+If we broke things (happens now and then), please tell us also.
+
+## Coding new features
+
+You have a cool idea for a feature that is missing in OpenTracks?
+And you would like to help by implementing it?
+If not, you can just take a look at the [issue tracker](https://github.com/OpenTracksApp/OpenTracks/issues).
+
+Advices:
+* creating an issue beforehand might be a good idea
+  Sometimes it is helpful to discuss your idea and also your implementation approach first.
+  We may be able to give you some hints on how to tackle the problem.
+  It also makes merging your changes easier and, usually, faster.
+* please only add new dependencies if is absolutely necessary
+  If you need to:
+  * tell us why those are required,
+  * what alternatives are existing, and
+  * why you choose this dependency.
+  And also verify that the license(s) are compatible with _Apache 2.0_ as well as open-source.
+ 
+## Coding conventions
+
+None so far.
+Just keep it simple.
+And follow the _scout rule_. 
+
+You can take a look at existing code and get a feeling for it.
+
+Please autoformat your code using AndroidStudio's code formatter.

+
+          "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
+          editorial revisions, annotations, elaborations, or other modifications

+
+          "Contribution" shall mean any work of authorship, including

+          (except as stated in this section) patent license to make, have made,
+          use, offer to sell, sell, import, and otherwise transfer the Work,

+          Contribution(s) alone or by combination of their Contribution(s)
+          with the Work to which such Contribution(s) was submitted. If You
+          institute patent litigation against any entity (including a
+          cross-claim or counterclaim in a lawsuit) alleging that the Work
+          or a Contribution incorporated within the Work constitutes direct
+          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.
+
+       END OF TERMS AND CONDITIONS
+
+       APPENDIX: How to apply the Apache License to your work.

 ## Custom Dashboards (incl. Map)
 As of v3.3.1 OpenTracks enables to use custom dashboards.
 The reference implementation is [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard), which presents an OpenStreetMap map (showing the current track, incl. updates).
 The developer documentation is in [README_API.md](README_API.md).
 
-Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)).
+Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand)).
 However, this is rather slow and does not provide updates while recording.
