This message “If your .htaccess file were writable, we could do this automatically, but it isn’t so these are the mod_rewrite rules you should have in your .htaccess file”

This page is not very user friendly for such a critical step in new installations for many new users. It is not clear how to allow .htaccess permision.

Can someone give me a simple paste this text: where? type screenshot. This link is not helpful https://codex.wordpress.org/Changing_File_Permissions

RewriteEngine On
RewriteBase /blog/
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]

It seems like using the default setting https://codex.wordpress.org/Changing_File_Permissions is actually NOT an option:
“For core WordPress files, all should be writable only by your user account. However, if you utilize mod_rewrite Permalinks or other .htaccess features you should make sure that WordPress can also write to your /.htaccess file. “

I saved my permalink settings from the default to month and name. But that does not seem to be enough.

Can anyone help? This seems like it would be a common problem.
