+# Support IE
+
+Earlier, this package might not work in IE11. The reason is that if popup and opener do not have same domain, popup cannot send message to opener. For more information about this, please visit [here](https://stackoverflow.com/questions/21070553/postmessage-still-broken-on-ie11). From `1.0.7`, we can bypass this by open a popup to our page, then redirect to Linked In authorization page, it should work fine. IE11 is supported in `1.0.7`. Following is step to support it. (If you don't have need to support IE, please ignore this part)  
+
+
+1. Pass prop `supportIE` 
+2. Pass `redirectPath`  which has path route to `LinkedinPopUp` component, default value is `/linkedin` (for above example, `<Route exact path="/linkedin" component={LinkedInPopUp} />` => `redirectPath="/linkedin"`)
+```
+<LinkedIn
+  ...
+  supportIE
+  redirectPath="/linkedin"
+  ...
