Sadly there is no easy way to do a PR for the wiki, so I'm writing this in an issue. Copy-pasting the markdown in the wiki should be enough.
Following #288 , condensers now have sidedness. Here is documentation to add to the "Alchemy" wiki entry for that.

Automating Condensers

Condensers inventory, both basic and advanced, are sided, just like vanilla blocks. This means the slot you can insert/extract from depends on the side with which you interact with the condenser.

Retorts do use a side and so prevent interaction from that side, unless you have some sort of remote interaction. Advanced condenser inventory can be accessed with the top block, while only the standard condenser's bottom block can be used for automation.

The sides behave like so:

• top (Advanced Condenser only): modifier slot
• back: bottle slot and fuel slots (Note that items that can be used as fuel in a furnace will never go in the bottle slot. You can still place them here yourself using the GUI)
• side and front: ingredients slots
• bottom: output slot (only extracting is possible, of course)

Fluid can be inserted from all faces using pipes.
