+[[state_dir]]
+==== 'state_dir'
+
+It contains global or system-wide state for osmo-gsm-tester. In a typical state
+dir you can find the following files:
+
+'last_used_msisdn.state'::
+	Contains last used msisdn number, which is automatically increased every
+	time osmo-gsm-tester needs to assign a new subscriber in a test.
+'lock'::
+	Lock file used to implement a mutual exclusion zone around the
+	'reserved_resources.state' file.
+'reserved_resources.state'::
+	File containing a set reserved resources by some osmo-gsm-tester
+	instance. Each osmo-gsm-tester instance is responsible to clear its
+	resources from the list once it is done using them and are no longer
+	reserved.
+
 If you would like to set up several separate configurations (not typical), note
 that the 'state_dir' is used to reserve resources, which only works when all
 configurations that share resources also use the same 'state_dir'.
 
+This way, several concurrent users of osmo-gsm-tester (ie. several
+osmo-gsm-tester processes running in parallel) can run without interfering each
+other (e.g. using same ARFCN, same IP or same ofono modem path).
