Since 2013, we have been giving credit to our fellow co-authors when integrating changes in our code bases. This was done by using commit message trailers like this one:

```auto
Co-authored-by: FirstName LastName <email@domain.org>

Here are the earliest occurrences of such acknowledgment: [commontk/CTK@9aa389d](https://github.com/commontk/CTK/commit/9aa389d2bfbd816b41229b517451912d891bc968) and [Slicer/Slicer@43808ca](https://github.com/Slicer/Slicer/commit/43808ca41265af260aae0b018032f0703392f834).

Additionally, we often use trailer like this one:

```auto
Thanks: FirstName LastName <email@domain.org>
Reviewed-by: FirstName LastName <email@domain.org>
Suggested-by: FirstName LastName <email@domain.org>

```
