+
+
+## Structure
+
+
+```
+    _______       ___________________       __________
+    |Nginx| ----> |google_auth_proxy| ----> |upstream| 
+    -------       -------------------       ----------
+                          ||

+                  [google oauth2 api]
+
+```
+
+## Configuration
+    
+1) visit to Google Api Console https://code.google.com/apis/console/
+2) under "API Access", choose "Create an OAuth 2.0 Client ID"
+3) Edit the application settings, and list the Redirect URI(s) where you will run your application. For example: 
+`https://internalapp.yourcompany.com/oauth2/callback`
+
+## Usage
+
+```
+./google_auth_proxy
+  -client-id="": the Google OAuth Client ID: ie: "123456.apps.googleusercontent.com"
+  -client-secret="": the OAuth Client secret
+  -cookie-secret="": the seed for cookie values
+  -redirect-url="": the http base to redirect to. ie: https://internalapp.yourcompany.com/oauth2/callback
+  -htpasswd-file="": additionally lookup basic auth in a htpasswd file. Entries must be created with "htpasswd -s" for SHA encryption
+  -pass-basic-auth=true: pass basic auth information to upstream
+  -upstream=[]: the http url(s) of the upstream endpoint(s). If multiple, routing is based on URL path
