+Otherwise known as `venvs`. Using conda to manage python virtual environments is beyond the scope of this document. But there is an important thing to know if you are using the windows portable build and installing custom nodes 'by hand'.
+* When instructions say to use python, you have to tell it to use the version of python in the standalone build.
+* to run "setup.py" from from the custom_nodes folder, requires a line something like this:
 
+```
+    ..\..\..\python_embeded\python.exe .\setup.py

+* this is so the correct python will be run and the required packages will be installed where comfyui can see them.
+* if using the manager, this isn't a concern since the manager is already using the correct python.
