-#### WSL 2 ####
+#### WSL V2 ####
 
-The new wslbridge2 gateway provides two versions, for WSL V1 and V2 mode, respectively.
-Mintty automatically detects the WSL version and invokes the proper gateway.
+Terminal communication with WSL via its modes V1 or V2 is handled 
+automatically by wsltty (mintty and the wslbridge2 gateway).
+
+#### Starting issues ####
+
+If wsltty fails with an 
+`Error: Could not fork child process: Resource temporarily unavailable`...,
+its runtime may be affected by some over-ambitious virus defense strategy.
+For example, with Windows Defender, option “Force randomization for images” 
+should be disabled.
+
+If wsltty fails with an error message that mentions a disk mount path (e.g. `/mnt/c`),
+workarounds may be the shutdown of the WSL V2 virtual machine (`wsl --shutdown` on the distro) 
+or turning off “fast startup” in the Windows power settings (#246, #248).
