+# php-ppub
 
+*Portable PUBlications for PHP*
 
+
 
+This is a simple blog engine using PPUB and PPIX formats that started with [PyPPUB](https://github.com/Tilo15/PyPPUB). It is minimalistic but configurable. It makes use of [Vanilla CSS](https://vanillacss.com/) and generates some very simple and standards compliant HTML.
 
+
 
+It can show an index based on a raw folder of ppub files, or it can be configured to use a PPIX index file to enable tags and searching.
