How can other people (who doesn’t know how to make a website) edit a website you’ve done for them?

If they have to update/change the particular website regularly…Does this mean they’re stuck along with one net developer

make a Content Software System as an alternative to standard HTML internet pages.
It can easily update or perhaps change the actual content of a website perhaps by anyone who doesn’t realize how to write the actual code

I don’t really fully grasp your query.If anyone doesn’t realize how to make an internet site ., he/she won’t be able to edit this.
