-# T5577 Writer App
+# T5577 Raw Writer App
+An easy to use T5577 raw writer app for Flipper Zero. 
+## Instruction:
 
+Configure the modulation, RF Clock, and number of blocks in the `Config` menu. The edit block feature is useless right not but will be implemented to allow editing user blocks in the future. 
+
+Or, you can load a .t5577 file into the app and write it. An example file can be found [here](https://github.com/zinongli/T5577_Raw_Writer/blob/b8f459c787802a443b2a943250b2ad8249f7c0ea/examples/Tag_1.t5577). The configuration will be automatically loaded from block 0 data. 
+
+The texts like:
+`Modulation: ASK/MC
+RF Clock: 64
+Number of User Blocks: 8`
+in the .t5577 files are derived from the block 0 data when saved. So if you want to adjust the configuration, you can simply edit block 0 data, without having to edit the text in the file. Or, you can load the data directly and adjust the configuration in the app before writing tags.
+
+You can also save the data you've just loaded and/or configured. 
+
+## Updates
+As of 2024-7-28, this app only supports writing from the file and load it into the app to write. 
+The feature of add manually is being developed and should be ready soon.
