## Installation & loading
PHPMailer is available via [Composer/Packagist](https://packagist.org/packages/phpmailer/phpmailer). Alternatively, just copy the contents of the PHPMailer folder into somewhere that's in your PHP `include_path` setting. If you don't speak git or just want a tarball, click the 'zip' button at the top of the page in GitHub.
PHPMailer is available via [Composer/Packagist](https://packagist.org/packages/phpmailer/phpmailer) (using semantic versioning), so just add this line to your `composer.json` file:
```json
"phpmailer/phpmailer": "~5.2"
```
or
```sh
composer require phpmailer/phpmailer
```
If you want to use the Gmail XOAUTH2 authentication class, you will also need to add a dependency on the `league/oauth2-client` package.
Alternatively, copy the contents of the PHPMailer folder into one of the `include_path` directories specified in your PHP configuration.. If you don't speak git or just want a tarball, click the 'zip' button at the top of the page in GitHub.
If you're not using composer's autoloader, PHPMailer provides an SPL-compatible autoloader, and that is the preferred way of loading the library - just `require '/path/to/PHPMailerAutoload.php';` and everything should work. The autoloader does not throw errors if it can't find classes so it prepends itself to the SPL list, allowing your own (or your framework's) autoloader to catch errors. SPL autoloading was introduced in PHP 5.1.0, so if you are using a version older than that you will need to require/include each class manually.

SPL autoloading was introduced in PHP 5.1.0, so if you are using a version older than that you will need to require/include each class manually.
PHPMailer does *not* declare a namespace because namespaces were only introduced in PHP 5.3.
If you want to use Google's XOAUTH2 authentication mechanism, you need to be running at least PHP 5.4, and load the dependencies listed in `composer.json`.
### Minimal installation
While installing the entire package manually or with composer is simple, convenient and reliable, you may want to include only vital files in your project. At the very least you will need [class.phpmailer.php](class.phpmailer.php). If you're using SMTP, you'll need [class.smtp.php](class.smtp.php), and if you're using POP-before SMTP, you'll need [class.pop3.php](class.pop3.php). For all of these, we recommend you use [the autoloader](PHPMailerAutoload.php) too as otherwise you will either have to `require` all classes manually or use some other autoloader. You can skip the [language](language/) folder if you're not showing errors to users and can make do with English-only errors. You may need the additional classes in the [extras](extras/) folder if you are using those features, including NTLM authentication, advanced HTML-to-text conversion and ics generation.

Generated documentation is [available online](http://phpmailer.github.io/PHPMailer/).
Examples of how to use PHPMailer for common scenarios can be found in the [examples](examples/) folder. If you're looking for a good starting point, we recommend you start with [the gmail example](examples/gmail.phps).
There are tips and a troubleshooting guide in the [GitHub wiki](https://github.com/PHPMailer/PHPMailer/wiki). If you're having trouble, this should be the first place you look as it's the most frequently updated.
Complete generated API documentation is [available online](http://phpmailer.github.io/PHPMailer/).
You'll find some basic user-level docs in the [docs](docs/) folder, and you can generate complete API-level documentation using the [generatedocs.sh](docs/generatedocs.sh) shell script in the docs folder, though you'll need to install [PHPDocumentor](http://www.phpdoc.org) first. You may find [the unit tests](test/phpmailerTest.php) a good source of how to do various operations such as encryption.
If the documentation doesn't cover what you need, search the [many questions on StackOverflow](http://stackoverflow.com/questions/tagged/phpmailer), and before you ask a question about "SMTP Error: Could not connect to SMTP host.", [read the troubleshooting guide](https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting).
