+#### Auto-Join Networks
+
+Define: 
+
+```
+ZT_NETWORK_IDS= [Network IDs with Space in between each ID]
+```
+
+
+The container will JOIN ALL the Networks mentioned in this variable and LEAVE ANY OTHER Network NOT defined in this variable.
+
+
+#### Health Checks
+
+Environment Variable Options:
+
+   1. Check For Specific Networks:
+
+        ```
+        ZT_CHK_SPECIFIC_NETWORKS=[Enter Specific Networks for checking with a space between each network; ALL Networks mentioned here would be checked; ZT_CHK_MIN_ROUTES_FOR_HEALTH is ignored if this is used.]
+        ```
+   
+   2. Check for Minimum number of Connections:
+
+        ```
+        ZT_CHK_MIN_ROUTES_FOR_HEALTH=[Should be a Number greater than 0; Ignored if CHK_ZT_SPECIFIC_NETWORK is used.]
+        ```
+    
+   3. Check for ALL Networks to be connected:
+     This is default mode when no Environment variable is defined.
+
+
+
 #### Router mode
 
 A variation on the container which implements a local network router. See:
