We'd love to accept your patches! Please read this guide first.
## Identity Disclosure
This project does not accept anonymous contributions. Justine Tunney
won't merge pull requests from strangers. In order to change the Cosmo
codebase, and have your changes be upstreamed, she has to know who you
are. You're encouraged to disclose your full name and email address to
the public too, by including them in your git commit messages; however
that's not a requirement; as we're happy to respect the wishes of
contributors who prefer to remain anonymous to the public.
## Copyright Assignment
Please send an email to Justine Tunney <jtunney@gmail.com> stating that
you intend to assign her the copyright to the changes you contribute to
Cosmopolitan. Please use the same email address you use for git commits
which should only contain original source code from you or other people
who are also assigning copyright. Please note that, if you're employed,
you may need to get your employer's approval beforehand. If you can not
assign copyright due to local laws, then you may alternatively consider
disclaiming it using the language in [Unlicense](https://unlicense.org)
or [CC-0](http://creativecommons.org/share-your-work/public-domain/cc0)
The first time you send a pull request, you need to send an email to
Justine Tunney <jtunney@gmail.com> stating that you intend to assign her
the copyright to the changes you contribute to Cosmopolitan. This only
applies to the code you *choose* to contribute. It only has to happen
once. The email should be sent from an email address associated with
your identity. Your email should link to your pull request.
This is important because we can't produce 12kb single-file executables
that comply with license requirements if we have to embed lots of them.
Although that's less of an issue depending on the purpose of the files.
For example, ownership is much less of a concern in the unit test files
so you're encouraged to put your copyright on those, provided it's ISC.
Please note that in order to give Justine the copyright, it has to be
yours to give in the first place. If you're employed, then you should
get your employer's approval to do this beforehand. Even with big
companies like Google, this process is quick and painless. Usually we
see employers granting authorization in less than one day.
If you live in a country that doesn't recognize one's ability to assign
copyright, then you may alternatively consider disclaiming it using the
language in [Unlicense](https://unlicense.org) or
[CC-0](http://creativecommons.org/share-your-work/public-domain/cc0).
If you're checking-in third party code, then you need to have headers at
the top of each source file (but never header files) documenting its
owners and the code should go in the `third_party/` folder. Every third
party project should have a `README.cosmo` file that documents its
provenance as well as any local changes you've made.

Cosmopolitan can be compiled from source on any of our supported
platforms. First, you need to download or clone the repository. If
you're not using x86-64 Linux then you'll need cosmocc too.
```sh
git clone https://github.com/jart/cosmopolitan cosmo

wget https://cosmo.zip/pub/cosmocc/cosmocc.zip

```sh
o//third_party/gcc/bin/make o//test/posix

```
Cosmopolitan provides a variety of build modes. For example, if you want
really tiny binaries (as small as 12kb in size) then you'd say:
```sh
o//third_party/gcc/bin/make m=tiny
build/bootstrap/make.com m=tiny
```
You can furthermore cut out the bloat of other operating systems, and
have Cosmopolitan become much more similar to Musl Libc.
```sh
o//third_party/gcc/bin/make m=tinylinux
build/bootstrap/make.com m=tinylinux
```
