I wanted the index page to be a static page (which you can write in the Ghost editor) rather than the list of posts (which you can only edit by changing the template). Hacked the router so the index page redirects to a static page at /index

gistfile1.js

var frontend    = require('../controllers/frontend');

module.exports = function (server) {
    /*jslint regexp: true */

    // ### Frontend routes
    server.get('/rss/', frontend.rss);
    server.get('/rss/:page/', frontend.rss);
    server.get('/page/:page/', frontend.homepage);
    server.get('/blog/', frontend.homepage);

    // Only capture the :slug part of the URL
    // This regex will always have two capturing groups,
    // one for date, and one for the slug.
    // Examples:
    //  Given `/plain-slug/` the req.params would be [undefined, 'plain-slug']
    //  Given `/2012/12/24/plain-slug/` the req.params would be ['2012/12/24/', 'plain-slug']
    //  Given `/plain-slug/edit/` the req.params would be [undefined, 'plain-slug', 'edit']
    server.get(/^\/([0-9]{4}\/[0-9]{2}\/[0-9]{2}\/)?([^\/.]*)\/$/, frontend.single);
    server.get(/^\/([0-9]{4}\/[0-9]{2}\/[0-9]{2}\/)?([^\/.]*)\/edit\/$/, frontend.edit);
    
    server.get('/', function(req, res) {
        req.params[1] = 'index';
        return frontend.single(req, res);
    });
};
