+
+## Python smart_open 1.7.1
+
+smart_open is a python library for efficient streaming of large files from/to HDFS, S3, HTTP, or local files.
+The simplest way to install `smart_open` is using `pip`
+
+``` pip install smart_open ```
+
+It is a good replacement for built-in open().
+It does everything open() can, and falls back to native open whenever possible.
+
+#### Why?
+
+It can be a pain while working with large S3 files using boto and boto3 libraries.
+`smart_open` builds on boto3 and is very simple to work with. 
+
+
+``` python
+import smart_open
+
+with smart_open.smart_open('s3://tmp-bucket/myfile.txt') as f:
+  lines = f.readlines()
+  for line in lines:
+    print line
+
+```
+
+`smart_open` is an open source software, maintained on [GitHub](https://github.com/RaRe-Technologies/smart_open)
