+
+As described in :ref:`i18n-new-language`, new and updated translations'
+availability is limited to new botogram releases, meaning that it could take
+some time for them to reach end users.
+
+Packaged translations may also not always fit a specific use case, making it
+necessary for you to edit some of the messages. While you could use a custom
+build of the package with a modified translation, it is also possible to
+programmatically override the translation of single messages through
+:py:attr:`botogram.Bot.override_i18n`, a dictionary that works basically the
+same way as a ``.po`` file, associating ``msgid``'s to ``msgstr``'s:

+        "Use /help to get a list of all the commands.": \

-Translating botogram to a new language is a non-trivial process and its effects
