Generated documentation for PHPMailer is available online, and is regenerated automatically whenever changes are made.
Pre-built PHPMailer API documentation is not provided in this repo, but you can generate it by running phpdoc in the top-level folder of this project, and documentation will be generated in this docs folder. You will need to have phpDocumentor installed. The configuration for phpdoc is in the phpdoc.dist.xml file.
Further help and information is available in the PHPMailer README, the examples folder, and in the GitHub wiki.
Fixes and additions to documentation are welcome - please submit pull requests or improve wiki pages.
