-#### open file in new process and make the nnn not block
+### Troubleshooting
 
-The desktop file opener should take care of opening files in new processes without causing `nnn` to block.
-If `nnn` does block/freeze when a file is open, then set the environment variable `NNN_NOWAIT` to any
-non-zero value.
+#### nnn blocks on opening files
+
+Ideally nnn should not block. Unfortunately, sometimes even the same desktop opener behaves differently on different Linux desktop environments. If `nnn` does block when a file is open, set the environment variable `NNN_NOWAIT` to any non-zero value. For example,
+
+    export NNN_NOWAIT=1
