If you keep the same license, then just add your name to it. Say it was this original license [https://github.com/mauro3/Parameters.jl/blob/master/LICENSE.md](https://github.com/mauro3/Parameters.jl/blob/master/LICENSE.md), then change it to something like:

```julia
Copyright (c): Mauro Werder (2015-2018), Han Hasse (2019)

```

If it is not the same type of license (or no license, or no open source license), then it’s more tricky.

Yes, but if it has an open source license you can use the code, subject to the license.
