+General-purpose OAuth 1.0 authentication strategy for [Passport](http://passportjs.org/).
+
+This module lets you authenticate using OAuth in your Node.js applications.
+By plugging into Passport, OAuth authentication can be easily and unobtrusively
+integrated into any application or framework that supports
+[Connect](http://www.senchalabs.org/connect/)-style middleware, including
+[Express](http://expressjs.com/).
+
+Note that this strategy provides generic OAuth support.  In many cases, a
+provider-specific strategy can be used instead, which cuts down on unnecessary
+configuration, and accommodates any provider-specific quirks.  See the
+[list](https://github.com/jaredhanson/passport/wiki/Strategies) for supported
+providers.
+
+Developers who need to implement authentication against an OAuth provider that
+is not already supported are encouraged to sub-class this strategy.  If you
+choose to open source the new provider-specific strategy, please add it to the
+list so other people can find it.
+
+## Install
+
+    $ npm install passport-oauth1
+
+## Usage
+
+#### Configure Strategy
+
+The OAuth authentication strategy authenticates users using a third-party
+account and OAuth tokens.  The provider's OAuth endpoints, as well as the
+consumer key and secret, are specified as options.  The strategy requires a
+`verify` callback, which receives a token and profile, and calls `cb`
+providing a user.
+
+    passport.use(new OAuth1Strategy({
+        requestTokenURL: 'https://www.example.com/oauth/request_token',
+        accessTokenURL: 'https://www.example.com/oauth/access_token',
+        userAuthorizationURL: 'https://www.example.com/oauth/authorize',
+        consumerKey: EXAMPLE_CONSUMER_KEY,
+        consumerSecret: EXAMPLE_CONSUMER_SECRET,
+        callbackURL: "http://127.0.0.1:3000/auth/example/callback",
+        signatureMethod: "RSA-SHA1"
+      },
+      function(token, tokenSecret, profile, cb) {
+        User.findOrCreate({ exampleId: profile.id }, function (err, user) {
+          return cb(err, user);
+        });
+      }
+    ));
+
+#### Authenticate Requests
+
+Use `passport.authenticate()`, specifying the `'oauth'` strategy, to
+authenticate requests.
+
+For example, as route middleware in an [Express](http://expressjs.com/)
+application:
+
+    app.get('/auth/example',
+      passport.authenticate('oauth'));
+    
+    app.get('/auth/example/callback', 
+      passport.authenticate('oauth', { failureRedirect: '/login' }),
+      function(req, res) {
+        // Successful authentication, redirect home.
+        res.redirect('/');
+      });
