CHOOSING A FOLDER
There are several ways to open a folder to be served by TinyServer.
• In the app, tap "Choose Folder", then long-press a folder to bring up the context menu. Choose "Serve in TinyServer"
• In the app, tap "Choose Folder", tap "Select" in the navigation bar, select a folder and tap "Open" in the navigation bar
• on iPad, you can have the files app and TinyServer side by side in multitasking. You can drag and drop folders to the top of the TinyServer interface. 
Keep in mind that this way creates a copy, so if you change the files you have to drag them to the app again to see the changes.

IMPORTANT:
The web server can not run in the background. Keep TinyServer in the foreground and the device unlocked. If you do change apps, the web server will restart automatically when you bring the TinyServer app back to the foreground.
TinyServer only works on local WiFi. The web server is not accessible via a cellular network connection.
It is meant for static files, so you can't run e.g. a PHP or Ruby on Rails backend from it.
