 Are you interested in bringing Actual to a broader audience by translating and localizing the app into new languages? Great! This guide will show you how to get started. Adding translations can be a great first step into contributing to open-source software.
 
-:::warning Community translations
+## Translating existing strings
 
-Currently, Actual Budget **is not yet ready** to receive community translations.
+Actual uses [Weblate](https://hosted.weblate.org/projects/actualbudget/actual) to manage all translations. In particular, we use Weblate's "suggestions" system to maintain high-quality translations.
+
+:::note Pull Requests
+
+We do not accept GitHub Pull Requests modifying translation files—any PRs in the translations repository will be automatically closed.

-## Current Status
+### Suggesting a new translation
+
+To suggest a translation for a language you are familiar with, just find a string you'd like to translate, fill in a translation, and hit "Suggest." This will then give others the opportunity to vote on the most accurate translation. Check out the [Weblate docs](https://docs.weblate.org/en/latest/user/translating.html) for more details.
+
+Please only fill in translations that you are confident in, and be sure to include the same formatting markers as the English text (example: `<1>English</1>` -> `<1>Anglais</1>`).
+
+### Voting on existing suggestions
 
-Actual is currently being prepared for internationalization (i18n). This means that initially everything in the app was English, but we're slowly marking all texts for translation.
+To help vote on high-quality strings, click on "Strings with suggestions" from a language page, and use the thumbs-up or thumbs-down icons to vote. If you click thumbs-down, it's always helpful to provide a reason so that the original translator can improve.
 
-## Marking for Translation
+## Marking new strings for translation
 
 Developing translated software requires that every text shown to the user passes through a translation function. Actual uses [i18next](https://www.i18next.com/) to achieve this goal.
