+## Frequently asked questions
+
+> Why would I want to write SQL instead of a real programming language? SQL is not even [Turing-complete](https://en.wikipedia.org/wiki/Turing_completeness)!
+
+ - You are probably worrying about the wrong thing. If you can express your application in a purely declarative manner, you should propably do it,
+   even if you are using a traditional programming language. 
+  It will be much more concise, readable, easy to reason about and to debug than any imperative code you could write.
+ - SQL is much more simple than traditional programming languages. It is often readable even by non-programmers, and yet it is very powerful.
+ - If you really want to make your website more complicated than it needs to be, please note that [SQL is actually Turing-complete](https://stackoverflow.com/questions/900055/is-sql-or-even-tsql-turing-complete/7580013#7580013).
+ - Even if it wasn't (if it didn't have recursive queries), a sequence of SQL statement executions driven by an user, like SQLPage allows you to do, would still be Turing-complete. You could build a sql website representing a Turing machine where the user would have to click "next" repeatedly to compute the next state of the machine.
+
+> Is this the same as Microsoft Access?
+
+The goal is the same: make it easy to create simple data-centric applications.
+But the tools are very different:
+ - SQLPage is a web server, not a desktop application.
+ - SQLPage is not a database, it _connects_ to real battle-tested databases. Microsoft Access tries to be a database, and it's [not very good at it](https://www.quora.com/Is-the-Access-database-reliable-and-secure).
+ - Microsoft Access is an expensive proprietary software, SQLPage is [open-source](./LICENSE.txt).
+ - Microsoft Access [is a zombie that will stab you in the back](https://medium.com/young-coder/microsoft-access-the-zombie-database-software-that-wont-die-5b09e389c166), SQLPage won't.
+ - SQLPage will not tortue you with [Visual Basic for Applications](https://en.wikipedia.org/wiki/Visual_Basic_for_Applications).
+
+> Is the name a reference to Microsoft Frontpage ?
+
+Frontpage was visual static website building software popular in the late 90s.
+I had never heard of it before someone asked me this question.
+
+> I like CSS, I want to design web site, not write SQL.
+
+Are you human ? [Human beings hate CSS](https://uxdesign.cc/why-do-most-developers-hate-css-63c92bce36ed).
+
+The take of SQLPage is that you should not spend time designing the border radius of your buttons until you have a working prototype.
+We provide a set of components that look decent out of the box, so that you can focus on your data model instead.
+
+However, if you really want to write your own HTML and CSS, you can do it by creating your own components.
+Just create a [`.handlebars`](https://handlebarsjs.com/guide/) file in `sqlpage/templates` and write your HTML and CSS in it. ([example](./sqlpage/templates/alert.handlebars))
