+
+Scope: All project spaces (issues, PRs, forums, events).
+
+Reporting: Email tom AT vondein DOT org. Acknowledge within 72 hours.
+
+Enforcement:    Two    maintainers     review,    one    recuses    on

+## Project Goals
+
+The idea behind this  project is to build a small commandline   tool to 
+manage an ElasticSearch cluster. 
+
+There  will  be no  GUI,  no  web interface,  no  public  API of  some
+sort. TUI subcommands maybe added.
+
+The  programming  language  used  for  this  project  will  always  be
+[GOLANG](https://go.dev/)  with  the  exception of  the  documentation
+([Perl POD](https://perldoc.perl.org/perlpod)) and the Makefile.
+
+# Contributing
+
+You can contribute to this project in various ways:
+
+## Open an issue
+
+If you encounter  a problem or don't understand how  the program works
+or if you think the documentation is unclear, please don't hesitate to
+open an issue.
+
+Please add as much information about the case as possible, such as:
+
+- Your environment (operating system etc)
+- program version
+- Input data. Please replace sensitive information with mock data!
+- Actual program output.
+- Expected program output.
+- Error message - if any.
+
+Be aware  that I  am working on  this (and some  other) project  in my
+spare  time which  is scarce.   Therefore  please don't  expect me  to
+respond to  your query within  hours or even  days. Be patient,  but I
+WILL respond.
+
+## Pull Requests
+
+Code and documentation help is  always much appreciated! Please follow
+thes guidelines to successfully contribute:
+
+-  Every  pull   request  shall  be  based   on  latest  `development`
+  branch. `main` is only used for releases.
+  
+- Execute the  unit tests before committing: `make  test`. There shall
+  be no errors.
+  
+- Strive  to be  backwards compatible  so that  users who  are already
+  using the program  don't have to change their habits  - unless it is
+  really neccessary.
+
+- Try to add a unit test for your addition.
+
+- Don't ever change existing unit tests!
+
+- Add a meaningful and comprehensive rationale about your contribution:
+  - Why do you think it might be useful for others?
+  - What did you actually change or add?
+  - Is there an open issue which  this PR fixes and if so, please link
+    to that issue.
+
+- [Re-]format your code with `gofmt -s`.
+
+- Avoid unneccesary dependencies, especially for very small functions.
+
+- **If** a  new dependency is being added, it  must be compatible with
+  our [license agreement](LICENSE).
+  
+- You  need to accept  that the  code or documentation  you contribute
+  will be redistributed under the  terms of said license agreement. If
+  your  contribution  is  considerably  large  or  if  you  contribute
+  regularly, then  feel free  to add  your name and  if you  want your
+  email    address     to    the    *AUTHORS*    section     of    the
+  manual page.
+
+- Adhere to the above mentioned project goals.
+
+-  If  you are  unsure if  your addition or  change will  be accepted,
+  better ask before starting coding. Open an issue about your proposal
+  and let's  discuss it! That way  we avoid doing unnessesary  work on
+  both sides.
+    
+Each pull  request will be  carefully reviewed and  if it is  a useful
+addition  it  will  be  accepted. However,  please  be  prepared  that
+sometimes a  PR will be  rejected.  The reasons  may vary and  will be
+documented.   Perhaps the  above guidelines  are not  matched, or  the
+addition seems  to be not so  useful from my perspective,  maybe there
+are  too  much  changes  or  there  might  be  changes  I  don't  even
+understand.
+
+But whatever happens: your contribution is always welcome!
