+# NASG - not another static generator...
 
+This is my semi-static generator, written in Python.
+Semi, because it generates 2 extra PHP files:
 
-magics:
-- automatic exif .json "cache" gets generated next to the source file
-    - updated if the cache timestamp < source file timestamp
-- on resize, forcing resize if resized timestamp < source timestamp
+- search.php to read and FTS4 based sqlite database for search
+- index.php to properly handle HTTP 410 and 301 headers for gone/redirect content
+
+Content is YAML + Markdown.
+
+External requirement: exiftool, because nothing else reads Lens data yet.
