 At the moment this project is very basic and just reads the cards from the txt file and emulates the NFC's but this is very early days of development and i wanted to make a basic version of my idea first
 
 ## How it works (As of the moment will change):
-When you start the app there is a start button when pressed starts the playlist
+When starting the app you are greeted by a select file option where you choose the playlist you wanna run.
 
-To set the playlist you need to create a file in ext/apps_data/nfc_playlist called playlist.txt you can find an example of the file in the repository
+All the playlists should be placed in ext/apps_data/nfc_playlist and an example of how the data in the file should look can be found below.
+```txt
+/ext/nfc/link.nfc
+/ext/nfc/link2.nfc
+```
+An example file can be found in the repository
 
 ## How to build
 This app was design, built and tested using the <a href="https://github.com/Flipper-XFW/Xtreme-Firmware">Xtreme firmware</a> i don't see why it wont work with other firmwares but do keep this in mind when building it with FBT/uFBT
 
 ## Ideas
-- [x] Add the ability to change playlist
+- [X] Add the ability to change playlist
 - [ ] Make it so changed settings are saved (maybe make it so settings can be specified for each playlist changing the settings based on the playlist selected)
