+# Bootcamp
+
+[![Build Status](https://travis-ci.org/vitorfs/bootcamp.svg?branch=master)](https://travis-ci.org/vitorfs/bootcamp)
+
+Bootcamp is an open source **enterprise social network** built with [Python][0] using the [Django Web Framework][1].
+
+The project has three basic apps:
+
+* Feed (A Twitter-like microblog)
+* Articles (A collaborative blog)
+* Question & Answers (A Stack Overflow-like platform)
+
+## Feed App
+
+The Feed app has infinite scrolling, activity notifications, live updates for likes and comments, and comment tracking.
+
+
+## Articles App
+
+The Articles app is a basic blog, with articles pagination, tag filtering and draft management.
+
+
+## Question & Answers App
+
+The Q&A app works just like Stack Overflow. You can mark a question as favorite, vote up or vote down answers, accept an answer and so on.
+
