 ### Day 1: Get `print8.ls8` running
+
 - [ ] Inventory what is here
 - [ ] Implement `struct cpu` in `cpu.h`
 - [ ] Add RAM functions `cpu_ram_read` and `cpu_ram_write`

 - [ ] Add the `PRN` instruction
 
 ### Day 2: Add the ability to load files dynamically, get `mult.ls8` and `stack.ls8` running
+
 - [ ] Un-hardcode the machine code
 - [ ] Implement the `cpu_load` function to load an `.ls8` file given the filename passed in as an argument
 - [ ] Implement a Multiply instruction and Print the result (run `mult8.ls8`)
 - [ ] Implement the System Stack and be able to run the `stack.ls8` program
 
 ### Day 3: Get `call.ls8` running
+
 - [ ] Implement the CALL and RET instructions
 - [ ] Implement Subroutine Calls and be able to run the `call.ls8` program
 
 ### Stretch
+
 - [ ] Add the timer interrupt to the LS-8 emulator
 - [ ] Add the keyboard interrupt to the LS-8 emulator
