# Contributing

Contributions should be made via pull requests. Pull requests will be reviewed
by one or more maintainers and merged when acceptable.

The goal of the Awesome Compose is to provide a curated list of application 
samples that can be easily deployed with [Docker Compose](https://github.com/docker/compose).

## Missing an example??

You can request a new example of an application by submitting an issue to our GitHub repository. 

Before submitting a new application, check if there isn't already application sample matching your need.

If there is one, consider updating it instead of creating a new one.
 
If you would like to submit a new application example, please start by submitting a proposal as an issue.
The maintainers will then use this issue to discuss what the most valuable example for the application,
 technology, language, or framework would be.

After the choice has been made, you can submit a pull request with the example remembering to:
- include an example README.md to describe the application and explain how to run/use the sample.
- edit the global README.md to add your sample in the repository main list.

## Commit Messages

Commit messages should follow best practices and explain the context of the
problem and how it was solved-- including any caveats or follow up changes
required. They should tell the story of the change and provide readers an
understanding of what led to it.

[How to Write a Git Commit Message](http://chris.beams.io/posts/git-commit/)
provides a good guide for how to do so.

In practice, the best approach to maintaining a nice commit message is to
leverage a `git add -p` and `git commit --amend` to formulate a solid
change set. This allows one to piece together a change, as information becomes
available.

If you squash a series of commits, don't just submit that. Re-write the commit
message, as if the series of commits was a single stroke of brilliance.

That said, there is no requirement to have a single commit for a pull request,
as long as each commit tells the story. For example, if there is a feature that
requires a package, it might make sense to have the package in a separate commit
then have a subsequent commit that uses it.

Remember, you're telling part of the story with the commit message. Don't make
your chapter weird.

## Sign your work

The sign-off is a simple line at the end of the explanation for the patch. Your
signature certifies that you wrote the patch or otherwise have the right to pass
it on as an open-source patch. The rules are pretty simple: if you can certify
the below (from [developercertificate.org](http://developercertificate.org/)):

```
Developer Certificate of Origin
Version 1.1

Copyright (C) 2004, 2006 The Linux Foundation and its contributors.

Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.

Developer's Certificate of Origin 1.1

By making a contribution to this project, I certify that:

(a) The contribution was created in whole or in part by me and I
    have the right to submit it under the open source license
    indicated in the file; or

(b) The contribution is based upon previous work that, to the best
    of my knowledge, is covered under an appropriate open source
    license and I have the right under that license to submit that
    work with modifications, whether created in whole or in part
    by me, under the same open source license (unless I am
    permitted to submit under a different license), as indicated
    in the file; or

(c) The contribution was provided directly to me by some other
    person who certified (a), (b) or (c) and I have not modified
    it.

(d) I understand and agree that this project and the contribution
    are public and that a record of the contribution (including all
    personal information I submit with it, including my sign-off) is
    maintained indefinitely and may be redistributed consistent with

```

Then you just add a line to every git commit message:

    Signed-off-by: Joe Smith <joe.smith@email.com>

Use your real name (sorry, no pseudonyms or anonymous contributions.)

If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`.
