Chapter "Change file system storage settings" in INSTALL.txt needs to be adapted to Drupal 8

Yes, it does need changing.

Removing extraneous tags, and adding Novice tag. Also fixing version.

Uploading first patch for this issue.

Thanks! This is a good start. A few thoughts:

1. Just before the part affected by this patch, INSTALL.txt says something about "the files directory created in step 4". It is actually in step 3. Let's fix this in this patch too?
2. I think we need to clarify in the new instructions that you can either enter a directory relative to the Drupal root, or else a full system directory starting with / ... although what about Windows? I have no idea...

4. Also... would someone who is not a coder know how to "uncomment" a line anyway? How about explicit instructions to remove the # at the start instead?

6. I think the part about private files should be a new paragraph, not a "Note".

Modifications are added as per the suggestions.

There are many ways to write the directory structure as per the documentation. Which way should be used in documentation?

Thanks, looking better!

   Can you make this into a complete sentence?

4. Regarding the question of how to explain what a file path is and how to specify it, I guess I would just say something like "relative to your Drupal installation directory" and leave it at that.

Done.

Looks great! One small thing:

Can we add 'and save the file' to this sentence too? Because as the patch is now, the only place it says to save the file is in the part about private files. So we should say it here too (either that or assume people would know to save the file and omit it in both places?) (probably saying "save the file" is fine though, but let's be consistent and do it in both places).

Incorporated suggested changes.

Now i think all the suggestions and corrections given by @jhodgdon in #5 , #8 and #10 are incorporated.
So making this RTBC.

Looks good to me too, thanks!

Looks like. Patch failing is due to unrelated reason. https://www.drupal.org/node/2724871

Changing status to RTBC as per previous comment.

Committed/pushed to 8.2.x, thanks!

And cherry-picked to 8.1.x...
