+# No Code of Conduct
+
+This project does  **NOT** have a so called Code  of Conduct, nor will
+it ever get one.
+
+The reasons are somewhat complicated and  I'll try my best to document
+them here.
+
+Ethical codes  or rules come  along like laws.  But how is  ethical or
+moral behavior defined? And who  defines which behavior is ethical and
+which is not? Certainly not me.
+
+Unless  you  live  in  a  dictatorship (and  more  than  half  of  the
+population of  planet earth  do as  of this  writing), laws  come into
+existence by democratic procedures. Laws  cover almost every aspect of
+live in  a society. Laws allow  and forbid behavior and  laws sanction
+infringements.
+
+A software project like  this one on the other hand  is not a society.
+There   are   not   enough   people  involved   to   form   democratic
+structures. And there will always be  a minority of users who have the
+right to commit or reject code. How could any maintainer of a software
+project dare to decree rules upon  others? Actually, am I, the current
+maintainer of this very project authorized to do so?
+
+I think the anser to this question clearly is NO.
+
+The  issue  is  being  complicated  by  the  fact,  that  open  source
+development these  days happens  on planetary  scale. And  this planet
+houses hundreds if not  thousands of different cultures, philosophies,
+ideologies and worldviews.  The answer  to many ethical questions will
+in most cases vague and nebulous.
+
+Ones joke will always be another ones insult.
+
+Then there  is the  problem of  language. I myself  am not  an english
+native, but I publish everyting using  the english language. I am able
+to communicate with  most people in the open  source community because
+of that.   But I am  certainly not  able to understand  everything and
+everyone. There  might be nuances to  a sentence I don't  sense, there
+might be  sarcastic connotations I  don't understand or  references to
+historical figures, events  or traditions I don't know  and never have
+heard of.
+
+Juding over other peoples online behavior looks like a titanic task to
+me. It  is just not my  job to judge  others. I am not  legitimized or
+authorized to do so.
+
+Another huge  problem with ethical rules  is that you need  to outline
+and enforce  sanctions on thos who  violate the rules. But  since I am
+not an  elected authority  how would  I be  able to  do this?  I don't
+know.  And what  happens if  someone complains  about myself?  Shall I
+remove myself from my own project? Come on!
+
+Last but  not least  there's the  law. I  am a  german citizen  and am
+living  in relatively  freedom.  Unlike  many other  people living  in
+democracies these days,  I myself fought for this very  freedom on the
+streets of  Leipzig in 1989.  I  saw the tanks, the  Stasi officers, I
+felt the  fear. But the laws  under I live  today and which I  have to
+adhere to, are only limited to the small speck on earth I am living on.
+
+So, let's say someone in india  says something insulting to some other
+developer in an issue.  Of course  german law does not apply to indian
+people. More, the insult might actually  not be an insult in india. In
+the end, nothing would happen. Under normal circumstances, maintainers
+would delete the posting, ban the user or remove push privileges etc.
+
+But then, is there a way for  the offending user to defend himself? Of
+course not, since neither indian or german law alone applies. I cannot
+go to  a german court  and sue the  guy and he  cannot do the  same in
+india. Or -  we possibly could but the judges  on both countries would
+just laugh and close the case.
+
+And let's not  even start talking about  there undemocratic "comitees"
+many projects are forming to  circumvent this problem.
+
+That  being said,  I  don't have  the  power nor  the  tools, nor  the
+authority to enforce serious sanctions  of any meaningful kind against
+others. Therefore I cannot outline any rules whatsoever.
+
+## So, which are the ethical rules within this project then?
+
+Well, there are none.
+
+This project is  about code, not society. It doesn't  matter where you
+come from,  how you look,  how you think,  what you believe,  who your
+friends are, whay you  said or did sometime in the  past. I don't even
+care if you are a human being. You are an alien so bored that you need
+to submit code on github? Fine with me.
+
+**The only thing I am interested here is Code and only Code.**
+
+So if anyhing happens here I don't like  or I am obliged by law to act
+on,  I  will  decide  on  a  case to  case  basis  what  to  do.   And
+unfortunately,  since this  is the  nature  of a  github project,  you
+cannot complain, object or protest. I am very sorry!
+
+If you will, let's at least  outline these:
+
+- Please - just please -  behave towards others as you'd expect others
+  to behave towards yourself.
+
+- Don't judge others for any reason.
+
+- Only judge the code.
+
+But these are not rules, only a  friendly appeal to you as a developer
+and user.
+
+
+Thanks a lot!

+## Project Goals
+
+The goal of this  project is to build a small tool  which helps in day
+to day  work with tabular  output of various commandline  programs. It
+should be small,  fast and easy to understand. The  idea is to replace
+multiline  shell  pipes  using  awk,   sed  and  grep  with  just  one
+binary.
+
+There will be no GUI, no web interface, no public API of some sort, no
+builtin interpreter.
+
+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)
+- tablizer version (`tablizer --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
+  [manpage](tablizer.pod).
+
+- 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!
