 > A Chrome extension that filters through Facebook Dev Circles around the world to get only the interesting posts in your feed.
 
+## Vision
+
+Instead of having dev circles according to locations, we can now have posts from various dev circles based on our interests.
+
+## What is it?
+
+It is a Google Chrome extension that replaces the feed of your Facebook Dev Circle group according to your interests.
+
+## What does it do?
+
+You put some keywords of your interest, say javascript, node.js, in the options of extension and when you run the extension on a Facebook group page (say your local Dev Circle), you get posts from various public dev circle groups which match your keywords, right into your feed.
+
+So instead of having dev circles by region, you now have dev circles by your interests!
+
+It has some pre-defined tags that help you add your keywords easily. You also have the option to blacklist certain groups, if you don't want to see posts from them (maybe due to language differences).
+
+It uses the graph API to fetch feeds from various dev circle groups.

+# How we built it?
+
+The extension uses the **Graph API** to fetch feeds from various dev circle groups. The posts shown in feed have same CSS classes as of regular posts in feed. We did this to make the feed look as natural as possible.
+
+The options page is written using the **React** framework. Used react components can be seen in GitHub repo.
+
+## Challenges we ran into
+
+1. Never built a Chrome extension before.
+2. Never used Graph API, React before.
+3. Finding the correct classes and minimal html for rendering posts in feed was quite a challenge.
+4. @sidvishnoi (the coder) was sick during development process.
+5. The other teammate (the one with original idea) was busy with out of station work.
+
+# Proud moments
+
+Making the posts and comments look similar to the ones shown in felt pretty cool. It seemed like I have finally built something.
+
+@sidvishnoi learnt react and webpack in one day and made the options page (not a lot, but enough to make it work).
+
+Creating a Chrome extension was also a fun thing to have done.
