 3 | ## Contributor License Agreements
 4 | 
 5 | We'd love to accept your sample apps and patches! Before we can take them, we 
 6 | have to jump a couple of legal hurdles.
 7 |

14 |   * If you work for a company that wants to allow you to contribute your work,
15 |     then you'll need to sign a [corporate CLA]
16 |     (http://code.google.com/legal/corporate-cla-v1.0.html).
17 | 
18 | Follow either of the two links above to access the appropriate CLA and
19 | instructions for how to sign and return it. Once we receive it, we'll be able to
20 | accept your pull requests.

35 | ## Contributing A New Sample App
36 | 
37 | 1. Sign a Contributor License Agreement, if you have not yet done so (see
38 |    details above).

41 |     * apps: quickstart, photohunt-server, photohunt-client
42 |     * example:  gplus-quickstart-android
43 |     * For multi-language apps, concatenate the primary languages like this:
44 |       gplus-photohunt-server-java-python.
45 | 
46 | 1. Create your sample app in this repo.
47 |     * Be sure to clone the README.md, CONTRIBUTING.md and LICENSE files from the
48 |       googleplus repo.
49 |     * Ensure that your code is clear and comprehensible.
