+# Passing Props Down To React-Router Route
+
+When using [react-router](https://github.com/ReactTraining/react-router),
+you'll often use the `component` prop to have a certain component rendered.
+
+```javascript
+<Route
+  path="/my/path"
+  component={MyComponent}
+/>
+```
+
+If, however, you need to pass props down into `MyComponent`, then you'll
+want to use the `render` prop with an inline function.
+
+```javascript
+<Route
+  path="/my/path"
+  render={(routeProps) => (
+    <MyComponent {...routeProps} {...props} />
+  )}
+/>
+```
+
+The two spread operator statements are essential. They will pass down the
+[route
+props](https://reacttraining.com/react-router/web/api/Route/Route-props)
+that `Route` would have passed down plus the additional set of props that
+you want to pass down.
