Translations for the OWASP Zed Attack Proxy help files: https://www.owasp.org/index.php/OWASP_Zed_Attack_Proxy_Project
If you'd like to translate ZAP to a language not on the list then let us know and we'll add it in.
Please note that the ZAP UI translations are handled in the http://crowdin.net/project/owasp-zap-help/
Please note that we have a policy that we only promote to proofreader those translators who have already made a significant number of translations. This is to ensure that we keep the translations as high quality as possible.
