Remember the questions you had when you first tried Friendica?
A good place to start can be to help new people find their way around Friendica in the [general support forum](https://helpers.pyxis.uberspace.de/profile/helpers).
Welcome them, answer their questions, point them to documentation or ping other helpers directly if you can't help but think you know who can.
Friendica uses [Composer](https://getcomposer.org) to manage dependencies libraries and the class autoloader both for libraries and namespaced Friendica classes.
It's a command-line tool that downloads required libraries into the `vendor` folder and makes any namespaced class in `src` available through the whole application through `boot.php`.
For the sake of consistency between contribution and general code readability, Friendica follows the widespread [PSR-2 coding standards](http://www.php-fig.org/psr/psr-2/) to the exception of a few rules.
Here's a few primers if you are new to Friendica or to the PSR-2 coding standards:
* By default, strings are enclosed in single quotes, but feel free to use double quotes if it makes more sense (SQL queries, adding tabs and line feeds).
* Operators are wrapped by spaces, e.g. `$var === true`, `$var = 1 + 2` and `'string' . $concat . 'enation'`
####Check with [PHP Code Sniffer](https://github.com/squizlabs/PHP_CodeSniffer)
This tool checks your files against a variety of coding standards, including PSR-2, and ouputs a report of all the standard violations.
You can simply install it through PEAR: `pear install PHP_CodeSniffer`
Once it is installed and available in your PATH, here's the command to run before committing your work:
$> phpcs --standard=PSR2 <fileordirectory>
The output is a list of all the coding standards violations that you should fix before committing your work.
Additionally, `phpcs` integrates with a few IDEs (Eclipse, Netbeans, PHPStorm...) so that you don't have to fiddle with the command line.
####Fix with PHP Code Beautifier and Fixer (phpbcf) included in PHP Code Sniffer
If you're getting a massive list of standards violations when running `phpcs`, it can be annoying to fix all the violations by hand.
Thankfully, PHP Code Sniffer is shipped with an automatic code fixer that can take care of the tedious task for you.
Here's the command to automatically fix the files you created/modified:
$> phpcbf --standard=PSR2 <fileordirectory>
If the command-line tools `diff` and `patch` are unavailabe for you, `phpcbf` can use slightly slower PHP equivalents by using the `--no-patch` argument.
If you are interested in having the documentation of the Friendica code outside of the code files, you can use [Doxygen](http://doxygen.org) to generate it.
