Transfer of the site to CMS WordPress

The client's site was on a self-written CMS, which was very uncomfortable, because the content was filled very hard, the blog was not, it was hard to do SEO promotion. All the directions had to be made through the company where the site was ordered.
I moved the site to WordPress, created a blog, put the directions in the design. The introduction of the editing takes place through the ACF plugin, all the fillings and changes the client can do on its own.
