Once you have created and populated your Content Groups, you then create a target-language document with a translation workflow.

By definition, translation jobs have both a source language and a target language. In order to leverage tools such as a translation memory (TM), we need both of these languages to be available in the workflow.

Given that an Adobe® InDesign® document is monolingual, we will need both our original source-language document and a separate target-language document. The target-language document is named a Version.

This is an excerpt from the workshop: Create a Translation Workflow.
