+### Translations: introduction ###

+Basic workflow for translations:
+ 1. developer adds a tr("foo") string in the code;
+ 2. every few days, a mantainer updates the *_en.ts files adding the new strings;
+ 3. Trasifex picks up the new files from github every 24 hours;
+ 4. translators translate the new untraslated strings on Transifex;
+ 5. before a release, a mantainer fetches the updated translations from Transifex.

 ### Translations (for developers) ###
 
 All the user-interface strings inside Cockatrice's source code must be written in
 english language. Translations to other languages are managed using [Transifex](https://www.transifex.com/projects/p/cockatrice/).

 translations from Transifex and commit them into the Cockatrice source code.
