 # 9086
 
-An binary compatible 8086 CPU with as many optimizations as possible
+A CPU that aims to be binary compatible with the 8086 and with as many optimisations as possible
+
+### Progress
+* [X] Executing code
+* [ ] can calculate the sieve of Eratosthenes
+* [ ] can boot up MS-DOS / FreeDOS
+* [ ] Is completely binary compatible
+* [ ] Is pipelined
+* [ ] Is Out of Order
+* [ ] Is superscalar
+
+### Building it
+To build it you need Icarus Verilog, bin86, GNU make, xxd and the posix coreutils.
+Go into the cpu directory and run `make`
+
+At the time of development the versions used are :
+
+* Icarus Verilog version 11.0 (stable)
+* bin86 version: 0.16.17
+* GNU Make 4.3
+* xxd 2022-01-14
+* GNU coreutils 8.32
