Although translating nodes is usually the bulk of the content translation burden, there might be "content" from other entities as well. This section walks us through the configuration for these non-node core entities, namely, comments, users, and taxonomy terms.
For each content type, you will need to decide if it makes sense to translate comments. If comments are coming from the general public, then it's unlikely that they should be translated. But, if there are comments that you control, then translating them might make sense. For example, if you have a company blog where only employees make comments and the blog posts will be translated, you might decide to translate the comments as well.
Unlike nodes, comments can only be handled using field translation as follows:
1. Navigate to Configuration | Regional and language | Entity translation.
2. Select the Comment checkbox and click on Save configuration.
3. Now we can enable field translation for any of our comment...
