 ## Advanced usage
 
 If you need to monitor more (or less) vars, you can specify them with -vars command line flag.
 
     $ expvarmon -help
-    Usage of ./expvarmon:
-    -dummy=false: Use dummy (console) output
-    -i=5s: Polling interval
-    -ports="": Ports for accessing services expvars (start-end,port2,port3)
-    -self=false: Monitor itself
-    -vars="mem:memstats.Alloc,mem:memstats.Sys,mem:memstats.HeapAlloc,mem:memstats.HeapInuse,memstats.EnableGC,memstats.NumGC,duration:memstats.PauseTotalNs": Vars to monitor (comma-separated)
-    Examples:
-        ./expvarmon -ports="80"
-        ./expvarmon -ports="23000-23010,80" -i=1m
-        ./expvarmon -ports="80,remoteapp:80" -vars="mem:memstats.Alloc,duration:Response.Mean,Counter"

 You can also monitor expvarmon itself, using -self flag.
 
+### Basic Auth
+
+If your expvar endpoint is protected by Basic Auth, you have two options:
+
+ - Set environmental variables *HTTP_USER* and *HTTP_PASSWORD* accordingly. These values will be applied to each endpoint.
+ - Embed your credentials to URL via command line flag: `-ports="http://user:pass@myapp:1234"`
+
 ### Vars
 
 Expvarmon doesn't restrict you to monitor only memstats. You can publish your own counters and variables using [expvar.Publish()](http://golang.org/pkg/expvar/#Publish) method or using expvar wrappers libraries. Just pass your variables names as they appear in JSON to -var command line flag.

-
-* ports auto-discovery for given hostname
-* more tests coverage
-* better usage of color highlighting (for max values or failed apps), after relevant patches will be merged to TermUI
