-# pan.do/ra site config overlay
+# pan.do/ra overlay for t-for-time
 
-fork this repo into pandora_sitename and add your pan.do/ra customizations
+pandora settings and render pipeline.
 
-place your config as config.jsonc, add custom files to static/js, poster scripts to scripts
+`apt install melt kdenlive ladspa-sdk xvfb`
 
-custom files should be in the form <file>.<sitename>.js
+`pandoractl manage genreate_clips`
 
-i.e. js overlay:
+`pandoractl manage render`
 
-    static/js/home.<sitename>.js
-
-png overly the same i.e.
-
- static/png/icon.<sitename>.png
-
-poster/icon script without <sitename>:
-    script/item_icon.py
-    script/list_icon.py
-    script/potser.py
-
-if you need a custom django module, touch __init__.py and install.py will take care of that too.
-
-to use js pages from other sites, add them to overwrite in install.py
-
-to deploy, checkout your fork into /srv/pandora/pandora/<sitename> and run ./install.py
