+Proxy set up
+--------------------------
+
+In proxies section, you can set up the proxy you want to 
+```ini
+[proxies]
+http=http.proxy.com:8080
+https=https.proxy.com:3128
+```
+or you can use the --proxies argument with dictionary data of proxy like:
+
+```
+{http: 'http.proxy.com:8080'}
+```
+
+
 The default naming convention for the credential section can be overriden by using the `--long-term-suffix` and
 `--short-term-suffix` command line arguments. For example, in a multi account scenario you can have one AWS account
 that manages the IAM users for your organization and have other AWS accounts for development, staging and production
