+# First wrote a brief overview of the first milestone of the project:
+- load files form the os
+- create the memory struct with read/write functions on the memory
+- create a cpu state with registers 
+
+# For the day:
+- Setup goland
+- Disable autocomplete on space because it doesn't work
+- Find ways to store memory state in go
+- Write memory module with read, write, writeall functions
+- Reading or writing outside of memory bounds will close app
+- Write cpu module with registers, PC, SP
+- Are registers only 8bits?
+- Where are instructions stored?
+
+# Conclusion
+- Can read roms from external files
+- Have a 64kb memory with functions to read and write to it
+- Have a cpu which reads instructions from the memory and increments the PC
