<h2 class="alert alert-success">Congratulations, your <a class="alert-link" href="http://luminusweb.net">Luminus</a> site is ready!</h2>
This page will help guide you through the first steps of building your site.
#### Why are you seeing this page?
The `home-routes` handler in the `cat.routes.home` namespace
defines the route that invokes the `home-page` function whenever an HTTP
request is made to the `/` URI using the `GET` method.
```
(defroutes home-routes
(GET "/" []
(home-page))
(GET "/docs" []
(-> (response/ok (-> "docs/docs.md" io/resource slurp))
(response/header "Content-Type" "text/plain; charset=utf-8"))))
```
The `home-page` function will in turn call the `cat.layout/render` function
to render the HTML content:
```
(defn home-page []
(layout/render "home.html"))
```
The page contains a link to the compiled ClojureScript found in the `target/cljsbuild/public` folder:
```
{% script "/js/app.js" %}
```
The rest of this page is rendered by ClojureScript found in the `src/cljs/cat/core.cljs` file.
#### Organizing the routes
The routes are aggregated and wrapped with middleware in the `cat.handler` namespace:
```
(defstate app
:start
(middleware/wrap-base
(routes
(-> #'home-routes
(wrap-routes middleware/wrap-csrf)
(wrap-routes middleware/wrap-formats))
(route/not-found
(:body
(error-page {:status 404
:title "page not found"}))))))
```
The `app` definition groups all the routes in the application into a single handler.
A default route group is added to handle the `404` case.

The `home-routes` are wrapped with two middleware functions. The first enables CSRF protection.
The second takes care of serializing and deserializing various encoding formats, such as JSON.
#### Managing your middleware
Request middleware functions are located under the `cat.middleware` namespace.
This namespace is reserved for any custom middleware for the application. Some default middleware is
already defined here. The middleware is assembled in the `wrap-base` function.
Middleware used for development is placed in the `cat.dev-middleware` namespace found in
the `env/dev/clj/` source path.

#### Database configuration is required
If you haven't already, then please follow the steps below to configure your database connection and run the necessary migrations.
* Create the database for your application.
* Update the connection URL in the `dev-config.edn` and `test-config.edn` files with your database name and login credentials.
* Run `lein run migrate` in the root of the project to create the tables.
* Let `mount` know to start the database connection by `require`-ing `cat.db.core` in some other namespace.
* Restart the application.
