# Contributing to Device Year Class
2+
We want to make contributing to this project as easy and transparent as
3+
possible.
4+
5+
## Our Development Process
6+
We work directly in the github project and provide versioned releases
7+
appropriate for major milestones and minor bug fixes or improvements. GitHub
8+
is used directly for issues and pull requests and the developers actively
9+
respond to requests.
10+
11+
## Pull Requests
12+
We actively welcome your pull requests.
13+
1. Fork the repo and create your branch from `master`.
14+
2. If you've added code that should be tested, add tests
15+
3. If you've changed APIs, update the documentation.
16+
4. Ensure the test suite passes.
17+
5. Make sure your code lints.
18+
6. If you haven't already, complete the Contributor License Agreement ("CLA").
19+
20+
## Contributor License Agreement ("CLA")
21+
In order to accept your pull request, we need you to submit a CLA. You only need
22+
to do this once to work on any of Facebook's open source projects.
23+
24+
Complete your CLA here: <https://code.facebook.com/cla>
25+
26+
## Issues
27+
We use GitHub issues to track public bugs. Please ensure your description is
28+
clear and has sufficient instructions to be able to reproduce the issue.
29+
30+
Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe
31+
disclosure of security bugs. In those cases, please go through the process
32+
outlined on that page and do not file a public issue.
33+
34+
## Coding Style
35+
* 2 spaces for indentation rather than tabs
36+
* Line wrapping indents 4 spaces
37+
* 100 character line length
38+
* One parameter per line when line wrapping is required
39+
* Use the `m` member variable prefix for private fields
40+
* Opening braces to appear on the same line as code
41+

# Device Year Class
2+
3+
Device Year Class is a library that implements a simple algorithm that maps
4+
a device's RAM, CPU cores, and clock speed to the year where those combination
5+
of specs were considered high end. This allows a developer to easily modify
6+
application behavior based on the capabilities of the phone's hardware.
7+
8+
## Integration
9+
10+
### Download
11+
Download [the latest JARs](https://github.com/facebook/yearclass/releases/latest) or grab via Gradle:
12+
```groovy
13+
compile 'com.facebook.device.yearclass:yearclass:1.0.0'
14+
```
15+
or Maven:
16+
```xml
17+
<dependency>
18+
<groupId>com.facebook.device.yearclass</groupId>
19+
<artifactId>yearclass</artifactId>
20+
<version>1.0.0</version>
21+
</dependency>
22+
```
23+
24+
### Calculate Device Year Class
25+
Calculating the current device's Year Class is simple.
26+
27+
```java
28+
int year = YearClass.get(getApplicationContext());
29+
```
30+
31+
Then, later on, you can use the year class to make decisions in your app, or
32+
send it along with your analytics.
33+
34+
```java
35+
if (year >= 2013) {
36+
// Do advanced animation
37+
} else if (year > 2010) {
38+
// Do simple animation
39+
} else {
40+
// Phone too slow, don't do any animations
41+
}
42+
```
43+
44+
See the `yearclass-sample` project for more details.
45+
46+
## Improve Device Year Class!
47+
See the CONTRIBUTING.md file for how to help out.
48+
49+
## License
50+
Device Year Class is BSD-licensed. We also provide an additional patent grant.
