👍🎉 Hello, and thanks for contributing to
GNSS-SDR! 🎉👍

Any code contributions going into GNSS-SDR will become part of a GPL-licensed,
open source repository. It is therefore imperative that code submissions belong
to the authors, and that submitters have the authority to merge that code into
the public GNSS-SDR codebase.

For that purpose, we use the
Developer's Certificate of Origin.
It is the same document used by other projects. Signing the DCO states that
there are no legal reasons to not merge your code.

To sign the DCO, suffix your git commits with a Signed-off-by: line. When
using the command line, you can use git commit -s to automatically add this
line. If there were multiple authors of the code, or other types of
stakeholders, make sure that all are listed, each with a separate
Signed-off-by: line.

Before submitting your pull request, please make sure the following is done:

1. You undertake the
   Contributor Covenant Code of Conduct.
2. You have read the
   Developer's Certificate of Origin
   and
   signed your commits
   as an indication of fulfillment.
3. You have read the
   Contributing Guidelines.
4. You have read the coding style guide.
   Specifically, you have read
   about clang-format
   and about clang-tidy,
   and you have applied those tools to your changes.
5. You have forked the
   gnss-sdr upstream repository and
   have created your branch from next (or any other currently living branch
   in the upstream repository).
6. Please include a description of your changes here.

Please feel free to delete this line and the above text once you have read it
and in case you want to go on with your pull request, and explain your intend
below.
