-## Troubles with pip
+## Frequently Asked Questions
+
+### I can't install dependencies on Windows
+
+It can appear that the problem is in filesystem permissions. Try running Blender from an administrator account and install dependencies in this mode.
+
+## I can't install dependencies on Linux, while using Blender installed from Snap
+
+Snap creates readonly file system, so you can't put depencencies into it. The only way known to work reliably is to not use Blender from Snap for Sverchok, if you want to use depencencies. The recommended way is to just download Blender's `tar.xz` from blender.org and unpack it.
