To start using the Tilde Drupal module, you'll need to provide your access key, select the translation engines, and configure the machine translation notice.
To add notice informing users that the content may be machine translated:
Go to Structure > Block layout.
Choose a region that appears on every page, e.g., Header. Note: position of MT notice will not change based on region – MT notice bar will always appear at the top of the page.
Click Place block.
Find a block called “Machine translation notice” and click Place block.
Configure block’s visibility settings – for example, by language. Typically, you would select every language supported by your MT provider, except the source language. That way MT notice will be shown for every language that may be machine-translated.
To manually edit the MT notice text for each language, find and update its translation in User interface translation settings.
