Psiphon is available on Android, iOS, and Windows.

2. Join the Psiphon Translation Team:

3. Download Psiphon:

Download Psiphon for the platforms you are translating! This is an important step that will allow you to get comfortable with the tool and view the original English strings and translations in context. Psiphon is available to download on Android, iOS and Windows.

4. Review the #Translation Guidelines:

Make sure you are familiar with the Translation Guidelines before you begin translating. They contain important information like whether or not to translate or transcribe the Project name.

5. Start Translating from the #Translation Priorities & Resources:

The list of resources and translation priorities will help you decide which content to work on first in the Psiphon project. Some resources are much more important to work on than others because they affect a larger number of Psiphon users. Dedicate your time on the resources that will make the most impact for users first.

Translation Guidelines

Do not translate "Psiphon."

Do not translate or transcribe "Psiphon". If you feel speakers of your language would benefit from a transcription of the project name, please place it in parentheses after the original name.
Example: Psiphon (سايفون)

Be aware of placeholders.

Many Psiphon strings contain placeholders which may replace HTML or XML tags or variables. It is important to retain those tags in the translation. You can move the placeholders depending on where they grammatically make the most sense in your language.
Variables in Transifex
Review the Transifex documentation to learn how to manage placeholders in the translation editor.
