func (p *Page) load() error {
    c, err := LoadConfig("config.json")
    if err != nil {
        return err
    }

    data, err := ioutil.ReadFile(p.File)
    if err != nil {
        return nil
    }

    p.HTML = string(blackfriday.MarkdownCommon(data))
    p.Title = c.Name()
    p.Author = c.Author()
    return nil
}
