+.. warning::
+    Mksh users have to set ``$POWERLINE_SHELL_CONTINUATION`` and 
+    ``$POWERLINE_SHELL_SELECT`` to 1 to get PS2 and PS3 (continuation and 
+    select) prompts support respectively: as command substitution is not 
+    performed in these shells for these prompts they are updated once each time 
+    PS1 prompt is displayed which may be slow.
+
+    It is also known that while PS2 and PS3 update is triggered at PS1 update it 
+    is *actually performed* only *next* time PS1 is displayed which means that 
+    PS2 and PS3 prompts will be outdated and may be incorrect for this reason.
+
+    Without these variables PS2 and PS3 prompts will be set once at startup. 
+    This only touches mksh users: busybox and dash both have no such problem.

     Job count is using some weird hack that uses signals and temporary files for 
     interprocess communication. It may be wrong sometimes. Not the case in mksh.
