 ENVIRONMENT VARIABLES
 ---------------------
+`LTTNG_UST_APP_PATH`::
+    Path under which unix sockets used for the communication between
+    the application (tracee) instrumented with `liblttng-ust` and the
+    LTTng session and consumer daemons (part of the LTTng-tools project)
+    are located. When `$LTTNG_UST_APP_PATH` is specified, only this path
+    is considered for connecting to a session daemon. The
+    `$LTTNG_UST_APP_PATH` target directory must exist and be accessible
+    by the user before the application is executed for tracing to work.
+    Setting this environment variable disables connection to root and
+    per-user session daemons.
+
 `LTTNG_HOME`::
     Alternative user's home directory. This variable is useful when the
     user running the instrumented application has a non-writable home
-    directory.
