 ## Running the examples
 
+> **NOTE**
+> It is essential to have a valid value of `GZ_PARTITION` environment variable
+> and to have it set to the same value in all open terminals. As `GZ_PARTITION`
+> is based on hostname and username, especially Windows and Mac users might
+> have problems due to spaces in their username, which are not a valid character
+> in `GZ_PARTITION`. gz-transport prints error `Invalid partition name` in such
+> case. To resolve that, set `GZ_PARTITION` explicitly to a valid value:
+> ```bash
+> # Linux and Mac
+> export GZ_PARTITION=test
+> # Windows
+> set GZ_PARTITION=test
+> ```
+
+> **NOTE**
+> On Windows, you can see firewall or antivirus prompts when running the examples.
+> For them to work properly, you should allow all communication to the
+> example programs.
