 ##How to use gist-embed to spice up code snippets on your blog
 
-### Include jQuery:
+### Include jQuery and gist-embed:
 
-    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
-
-### Include gist-embed (If your blog doesn't accept local file includes, then simply copy paste the contents into a script tag):
+  You should include them in your HEAD tag for better performance
 
-    <script type="text/javascript" src="gist-embed.js"></script>
+    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
+    <script type="text/javascript" src="https://github.com/kashif-umair/gist-embed/raw/master/gist-embed.js"></script>
 
 ### Add a code element to your page with an id attribute in the following format:
 
     "gist-<gist-id>"
-	e.g.:
-    <code id="gist-1741"></code>
-    <code id="gist-4147951" data-file="file1.txt"></code>
\ No newline at end of file
+### To embed the whole gist you should put this code element in your body where ever you want it to be displayed.
+    <code id="gist-4672365"></code>
+### To embed a single file from gist, add the data-file attribute to your code element like this.
+    <code id="gist-4672365" data-file="2.java"></code>
+### To embed a single line of a file from gist, add the data-line attribute to your code element like this.
+    <code id="gist-4672365" data-file="2.java" data-line="5"></code>
+    
+    This will embed only line number 5.
+### To embed multiple lines of a file from gist, change the data-line attribute's value to something like MS Word printing page ranges. e.g.
+    <code id="gist-4672365" data-file="2.java" data-line="2-5,10-14,11,20"></code>
+    
+    This will embed line numbers 2,3,4,5,10,11,12,13,14,11,20 in the same order. If lines are duplicated then they will be duplicated in code too.
+
+#### If you are embedding multiple lines then make sure about following points.
+
+ - You can put a range like "2-5", or single line numbers separated with commas like "11,20", or mix of both like "2-5,11,10-14,20"
+ - Spaces are not allowed in data-line value
+
+#### Follow the above instructions to avoid getting any undesired results.
