 ## How To Use

 Main (and the only) function you can use is **ViragDevTool_AddData(data, "some string name")**:
+
 ```lua
 --- Adds data to ViragDevTool UI list to monitor
 -- @param data (any type)- is object you would like to track.

+#### Here is how i use ViragDevTool_AddData:
+```lua
+--define print fn so we can easily turn it off
+function MyOtherAddon_Print(strName, tData)
+    if ViragDevTool_AddData and MyOtherAddon.kbDEBUG then
+        ViragDevTool_AddData(tData, strName)
+    end
+end
+
+-- use this function all over my code instead of print
+MyOtherAddon_Print("MyOtherAddon", MyOtherAddon) -- sends object to UI
+```
+### How to use sidebar:
+There are 3 tabs in sidebar and text field has different behavior in each tab.
+
+* **In \vdt history tab** it is just easy way to call `/vdt ...` for example you can print `find Virag` and it is the same as printing `/vdt find Virag` in chat
+
+* **In Events tab** textfield can only use `eventname` or `eventname unit` and this is the same as `/vdt eventadd eventname` or `/vdt eventadd unit` where eventname is Blizzard API event(http://wowwiki.wikia.com/wiki/Events_A-Z_(Full_List)) string name
+For example: `UNIT_AURA player` in textbox is the same as `/vdt eventadd UNIT_AURA player` in chat
+```lua
+if unit then f:RegisterUnitEvent(event, unit)
+else f:RegisterEvent(event) end
+```
+![ViragDevTool events demo][eventsDemo]
+
+* **In Fn Call Log** tab you can type `tableName functionName` into textfield and it will try to find `_G.tableName.functionName` and if this field is a function it will be replaced with logger function like this:
+```lua
+tParent[fnName] = function(...)
+   ViragDevTool:Add({ ... }) -- will add args to the list
+   local result = { savedOldFn(...) }
+   ViragDevTool:Add(result) -- will add return value to the list
+   return unpack(result)
+end
+```
