 # discord-timestamp
+Reliably create timestamps for Discord entirely within the terminal!
+Mainly made in mind with Linux (Although it will in the future work on Windows too)
 
+## plan
+The program should run purely in the terminal, working on Windows and Linux.
+It should take a couple of commandline arguments based on 
+
+1. What time format (By default 'f').
+2. Short format (HH MM SS) or long format (DD MM YY HH MM SS)
+
+It start the output as: 
+- Current time
+- Information on what to input
+- User input
+
+Do input validation, then output as a copyable format whilst waiting for input before
+continuing.
+
+### Possible additions
+Allow for the user to pass the output into a file for use in the longer term.
+
+Directly allow input using the parser alone.
+## progress
+- [ ] Set up the startup sequence & basic input (and output)
+- [ ] Add a basic system for inputting time and outputting (correct) epoch time
+- [ ] Properly implement commandline parsing as stated in the plan
