Write language-add.txt

Great! I made a few small changes to your file - formatting mostly. Also, after you started work on this, we added some things to the template/instructions regarding screen shots... So ... can you take this slightly modified file as a starting point, and work on this a bit more, with screen shots?

Also we need your "attributions" information -- please just paste into a comment how you would like this to appear.

https://userguide-drupal.redesign.devdrupal.org/guidelines/good-writing.... (see the text/images section)
https://userguide-drupal.redesign.devdrupal.org/guidelines/guidelines.ht... (attributions)

We decided to use separate issues for each phase of writing/editing.

This still needs attributions information and rough screen shots (see the @todo note in the file I uploaded in #5), and then I think we can put it in the Guide. Thanks!

Hi! Are you still working on this? Hopefully yes -- if not, please comment here and let us know we need to find someone else. And if you are, do you know when you might finish writing this topic?

By the way... there have been quite a few updates to our processes since the sprint where you took this on. For one thing, we have a more concise guide to contributing (with links to specific instructions) on the project page:
https://www.drupal.org/project/user_guide

Also, the templates and some guidelines have changed, especially in the area of screen shots and images.

And we've finally made a complete outline for the guide! See
https://userguide-drupal.redesign.devdrupal.org/d8guide/en/index.html
to find your topic, along with its new template.

Thanks!

We also put more notes about what each topic should cover in the tracking spreadsheet; see
https://docs.google.com/spreadsheets/d/1ov0FyJhKrJe7PYvohzV5UrrLyRaVCy2A...
for that.

Adding checklist to summary and updating summary for current plans for this topic.

Still needs attributions information, and some work on the topic. Thanks!

@yrvyn: Do you still plan to finish up this topic? If so, do you have a time frame? If not, please unassign the issue so someone else can work on it. Thanks!

And even if you do unassign the issue, please add your attributions information to the issue summary, so that you get proper credit for the work thus far. It's really almost ready...

I'll try to incorporate the remarks.

yrvyn: please re-assign if you want to continue.

New version:

- adding a screenshot
- rephrased a couple of sentences
- removed the link to language-update.txt. This probably does not exist anymore

This looks good to me! I did a few very small edits and committed it:
- Fixed the title
- In prerequisites, the language-concept link text would match what was in the file just before it, so I made it just a link.
- We don't have a topic yet about language switching, and the Installing modules topic will not cover it, so I converted this follow-on task into a @todo note.
- Navigation was *almost* the way we wanted it but not quite, so rather than open a new issue to fix that, I just fixed it.
- Screen shot didn't have a comment explaining how to do it.

Sorry for the long delay in reviewing this -- I've been on vacation.

Also for the attribution, I did not see any text from https://www.drupal.org/resource-guides/configuring-multilingual-site that was used there, so I omitted the "adapted by" part, and credited all who worked on this topic.

Added to the source; will be up on the site shortly!
