-### What are the requirements?
-- A machine with [Rustc Tier 1 platform support](https://doc.rust-lang.org/nightly/rustc/platform-support.html#tier-1-with-host-tools)
-- Rustup
-- QEMU (for executing)
-- GIT CLI
-
-### How do I run ableos?
-- It is recommended to run ableos under QEMU. Here is how:
-    - Install QEMU
-    - Clone ableos
-    - Go to ableos directory
-    - Pull the limine submodule with `git submodule update --init`
-    - Run `cargo repbuild help`
-
-### How can I contribute?
-- [Contribute code](#how-do-i-contribute-code)
-- [Run ableos on your machine](#how-do-i-run-ableos)
-- Find bugs
-- Create media showing ableos
-
-### How do I contribute code?
-- Start by forking ableos
-- Write something that runs in the userspace, for example:
-    - System drivers
-    - Programs
-    - Libraries
-- Patch bugs and improve code in the kernel
-- Ensure that the code is OK to be maintained by asking in the [discord](https://discord.gg/t5Wt3K4YNA)
-- When you have finished your changes, you can submit a pull request for review [here](https://git.ablecorp.us/ableos/ableos)
-
-### repbuild and kernel compile, but QEMU isn't starting
-- Ensure you have the `qemu-desktop-{arch}` for your OS and target architecture installed
-- Try running again with `--noaccel` if you have QEMU already
-
-### I have run using repbuild but it's slow
-- Ensure release mode is enabled with the `-r` flag
-- Remove the `--noaccel` flag if you can
-- If both of these are already done, there may be a problem with thee VM, kernel, your program, or the hblang compiler
-
-### Compiler is complaining about "reg id leaked"
-- [Submit](#how-do-i-report-a-compiler-bug) an issue, reg id leaked is a bug
-
-### My program isn't running
-- Refer to [here](#i-have-run-using-repbuild-but-its-slow), it may be that your program is simply starting slowly
-- Ensure that your program has a properly written meta.toml file
-- Ensure that your program is enabled in [system_config.toml](sysdata/system_config.toml)
-- Try running again with `--noaccel`, there is a known bug with some systems that prevents programs from starting.
-
-### Kernel panic??? Huh???
-- Kernel panics can be caused by improperly using memory (e.g, writing out of bounds)
-- Kernel panics are most likely to be caused when accessing memory or using `@eca` for kernel ecalls
-- [Report](#how-do-i-report-an-ableos-bug) a kernel panic
-
-### I am running in release mode but I have no debug info
-- Add the `-d` flag for debug info
-
-### What is `@eca`? How do I use it?
-- Eca is an ecall. They are similar to syscalls
-- The `@eca` directive takes the following arguments:
-    - `@eca(ecall_number, reg_1, ..., reg_n)`
-- The various ecalls have different arguments that are given by register values
-- Most ecalls are wrapped by `stn`, for example, `random`, `buffer`, and `memory` all make use of ecalls
-- All ecalls can be found [ecah.rs](kernel/src/holeybytes/ecah.rs)
-
-### How do I report an ableos bug?
-- Submit an issue [here](https://git.ablecorp.us/ableos/ableos/issues) or report it in the [discord](https://discord.gg/t5Wt3K4YNA)
-
-### How do I report a compiler bug?
-- Submit an issue [here](https://git.ablecorp.us/ableos/holey-bytes/issues) or report it in the [discord](https://discord.gg/t5Wt3K4YNA)

+
+`cargo repbuild doc`
+`cargo repbuild run`
+
+## Testing on real hardware
+I recommend using an old x86_64 computer
+* `cargo run --release` to generate a binary image that is bootable
+* flash it to a USB device via `dd` or balenaEtcher
+* Remove said USB device and plug into test machine
+* assure test machine boots from USB devices

STYLE_GUIDE.md

@@ -1,77 +0,0 @@
-# Style Guide
-This style guide has two modes that a guideline may be.
-
-`strict` means that prs will be rejected if they do not follow the guideline.
-
-`loose` means that a pr would be accepted but should later be fixed.
-
-## Empty Functions | loose
-Empty functions are typically a sign of an unfinished program or driver.
-
-In cases where there is a clear reason to have an empty function it will be allowed.
-For example FakeAlloc is only empty functions because it is a example of an the allocator api.
-
-### Allowed
-```rust
-/// in example.hb
-a := fn(): void {}
-```
-### Not Allowed
-```rust
-/// in fat32.hb
-a := fn(): void {}
-```
-## Magic Functions | loose
-'Magic functions' are what I am calling small helper functions that do one or two things.
-### Example
-```rust
-a := null
-magic_a := fn(){
-	a = 10
-}
-```
-The exact policy I want to have here is a bit fuzzy. I think that functions like this are nice in certain situations and not in others.
-Regardless of if you use them or not, put a comment above the function explaining rational.
-
-
-## Magic Numbers | loose
-The policy on magic numbers is make them const and have a comment above them. Typically linking to a source of information about the magic number.
-
-This helps cut down on magic numbers while making acceptable names and atleast half assed documentation. 
-
-Constants are inlined anyways, so its the same thing in the binary.
-
-```rust
-// The standard vga port is mapped at 0xB8000
-$VGA_PTR := 0xB8000
-```
-
-## Tabs Vs Spaces | strict
-I prefer for hblang code to use hard tabs.
-
-The rational behind this is that a tab is `1 Indent` which some developers might want to be various different sizes when displayed
-
-Soft tabs do not allow this user/editor specific as soft tabs always become spaces.
-
-Bottom line is this is an accessibility feature.
-
-There are some samples below.
-```
-\t means hard tab
-\n means new line
-\0x20 means space
-```
-
-### Allowed
-```rust
-if x == y {\n
-\tlog(z)\n
-}\n
-```
-
-### Not Allowed
-```rust
-if x == y {\n
-\0x20\0x20\0x20\0x20log(z)\n
-}\n
-```
