individual you can donate tax-free to NLNet, and they can in turn gift
our developers. Contact lkcl@lkcl.net for more information.

If you want to write code with us (and receive donations from NLNet
for doing so), keep reading. If you want to *learn*
just get in touch on the list, there is plenty to do.
1. First, join the
-[mailing list](http://lists.libre-riscv.org/mailman/listinfo/libre-riscv-dev),
-introduce yourself (people will happily say "hello" back"). Read through
-[recent posts](http://lists.libre-riscv.org/pipermail/libre-riscv-dev/)
-and the [[charter]], and let everyone know, on the list that you're
-happy with it and agree to it.
-2. The next thing you should do is read through the [bugs
-list](http://bugs.libre-riscv.org) and see if there are any bugs that
-pique your interest.
-3. After that, go ahead and take a look at the [git repositories](https://git.libre-riscv.org).

## How can I learn?
We also need to find a c++ engineer with compiler experience to work on
a MESA 3D driver. This will begin life similar to SwiftShader however
-retaining the vectorisation and predication intrinsics as well as hardware
-accelerated opcodes (all of which SwiftShader lacks)

Also, individuals with experience in formal mathematical verification
are quite welcome.
