CMS – One abbreviation for Content Management System. It can be used for lot of things. I have mostly is used it for web development and design, but it can be used for ERP, CMS for Business portals etc.
So, in short it s – how it is to switch from one big CMS (namely WordPress) to smaller hacker based JAMStack based CMS (Jekyll with HTML5, CSS & Vanilla JS for design) after years of usage that big CMS.
Next move for this web site is integration of better PWA, maybe AMP feature and finishing of SEO things which is sort-of necessary in today web world.
