create a blog like application

Hello guys i have a non game project that i am trying to achieve with unity im alsow using ngui

And it is to create a blog like application , where you will have posts (articles) that will be displayed in a time line ( like facebook)

But the probleme is that i want to know how can i feed my aaplication that content(posted content) without having to update the app itself , is there a way i would have the articles and pictures hosted in a website , and that i will be able by updating the website , to have the content of the application updated aswell ?

for exemple if i create a new aarticle today , i want it to be added to the time line as the lastest news , and so on , a be able to create an article every day , a feed it to the app

Is there an asset on the assetstore that do this , if not do you have an idea how can i achieve that result , any help will be appreciated thanks a lot !
