+### 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)

 # Compiling
-AbleOS should be able to be built on any platform which is supported by
-[Rustc Tier 1 platform support](https://doc.rust-lang.org/nightly/rustc/platform-support.html#tier-1-with-host-tools).
-
-For running AbleOS, `repbuild` uses QEMU.
-
-## Steps
-1. Ensure you have qemu installed
-2. `git submodule update --init`
-3. `cargo repbuild run`
+See [HELP.md](HELP.md)

-There is a new work in progress developer tool for hblang.
