+class SSLAdapter(HTTPAdapter):
+    """
+    A HTTPS Adapter for Python Requests that allows the choice of the SSL/TLS
+    version negotiated by Requests. This can be used either to enforce the
+    choice of high-security TLS versions (where supported), or to work around
+    misbehaving servers that fail to correctly negotiate the default TLS
+    version being offered.
+
+    Example usage:
+
+        >>> import requests
+        >>> import ssl
+        >>> from requests_toolbelt import SSLAdapter
+        >>> s = requests.Session()
+        >>> s.mount('https://', SSLAdapter(ssl.PROTOCOL_TLSv1))
+
+    You can replace the chosen protocol with any that are available in the
+    default Python SSL module. All subsequent requests that match the adapter
+    prefix will use the chosen SSL version instead of the default.
+
+    This adapter will also attempt to change the SSL/TLS version negotiated by
+    Requests when using a proxy. However, this may not always be possible:
+    prior to Requests v2.4.0 the adapter did not have access to the proxy setup
+    code. In earlier versions of Requests, this adapter will not function
+    properly when used with proxies.
