Hi @rogyar this PR should contain all the changes you recommended me t apply in a previous PR. Could you please have a look and let me know if so see something missing? Thanks

Hi @diazwatson. I'm not sure how you were able to create an exact copy of the existing guide :)
guides/v2.3/config-guide/config/config-files.md already exists but this PR shows it as a new file. Maybe there's an issue in the file path (encoding issue) or so.

Also, please, take a look at the review for PR with the same idea. There are some additional ideas that need to be implemented in order to cover all the information requested in the original issue.

Thank you

@diazwatson , a correct file location - src/guides/v2.3/config-guide/config/config-files.md

Please pull the latest changes from master branch!

Thank you!

Thanks @atwixfirster I got confused because one of the initial recommendation was to add this changes to 2.2 and 2.3 and it was valid for both versions. I'll update this PR with the correct location today. 👍

@diazwatson please note, what we do not accept PRs with updates for 2.2 version. So, please add your updates for 2.3 only.

Thanks
