Facebook has recently introduced Story adding feature. Now they are providing archiving of your stories. It means you can see all your posted stories at one place.
Open facebook app on your phone and at home page in stories section look at the top right corner. Story Archive is written there. Click on it.
At the next page it will show you a message like this. Allow it by pressing OK. It is just telling you about this feature.
Finally you can see the stories available in your facebook stories. Currently i have no story so you can't see anything but if you have posted any in past then you can see them here.
