+### 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)

-## 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

@@ -0,0 +1,77 @@
+# 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
+```
