Here is a short description of the requirements for using CMSimple_XH. More detailed information can be found in the wiki.
A working internet connection is required. ;-)
CMSimple_XH requires a Web-server running at least PHP 5.3 (recommended 5.6 or higher). A database is not required. Apache servers are often used by the relevant providers - but CMSimple_XH also works on other systems (successfully tested with e. g. IIS and NGINX).
Of course you need a computer to work with CMSimple_XH. The installed operating system does nor matter - however, an up-to-date Web-browser should be available.
It would also be important to have an FTP program (such as Filezilla), with which you can upload files and - if necessary - assign the necessary write and read permissions to the folders and files on the server.
To test CMSimple_XH offline at home or perhaps for portable presentations, there are (at least) two ways:
htdocs). If you want to experiment with the template design, you also need a text editor that can edit UTF-8 files without BOM (Byte Order Mark) (e. g. Notepad++).
