 Porffor is primarily built from scratch, the only thing that is not is the parser (using [Acorn](https://github.com/acornjs/acorn)). Binaryen/etc is not used, we make final wasm binaries ourself. You could imagine it as compiling a language which is a sub (some things unsupported) and super (new/custom apis) set of javascript. Not based on any particular spec version, focusing on function/working over spec compliance.
 
+## Usage
+Expect nothing to work! Only very limited JS is currently supported. See files in `bench` for examples.
+
+### Setup
+1. Clone this repo
+2. `npm install` - for parser(s)
+
+### Running a file
+The repos comes with easy alias files for Unix and Windows, which you can use like so:
+- Unix: `./porf path/to/script.js`
+- Windows: `.\porf path/to/script.js`
+
+Please note that further examples below will just use `./porf`, you need to use `.\porf` on Windows. You can also swap out `node` in the alias to use another runtime like Deno (`deno run -A`) or Bun (`bun ...`), or just use it yourself (eg `node runner/index.js ...`, `bun runner/index.js ...`). Node and Bun should work great, Deno support is WIP.
+
+### Trying a REPL
+**`./porf`**. Just run it with no script file argument.
+
+### Compiling to native binaries
+> [!WARNING]
+> Compiling to native binaries uses [2c](#2c), Porffor's own Wasm -> C compiler, which is experimental.
+
+**`./porf native path/to/script.js out(.exe)`**. You can specify the compiler with `-compiler=clang/zig/gcc`, and which opt level to use with `-cO=O3` (`Ofast` by default). Output binaries are also stripped by default.
+
+### Compiling to C
+> [!WARNING]
+> Compiling to C uses [2c](#2c), Porffor's own Wasm -> C compiler, which is experimental.
+
+**`./porf c path/to/script.js (out.c)`**. When not including an output file, it will be printed to stdout instead.
+
+### Compiling to a Wasm binary
+**`./porf compile path/to/script.js out.wasm`**. Currently it does not use an import standard like WASI, so it is mostly unusable.
+
+### Options
+- `-target=wasm|c|native` (default: `wasm`) to set target output (native compiles c output to binary, see args below)
+- `-target=c|native` only:
+  - `-o=out.c|out.exe|out` to set file to output c or binary
+- `-target=native` only:
+  - `-compiler=clang` to set compiler binary (path/name) to use to compile
+  - `-cO=O3` to set compiler opt argument
+- `-parser=acorn|@babel/parser|meriyah|hermes-parser` (default: `acorn`) to set which parser to use
+- `-parse-types` to enable parsing type annotations/typescript. if `-parser` is unset, changes default to `@babel/parser`. does not type check
+- `-opt-types` to perform optimizations using type annotations as compiler hints. does not type check
+- `-valtype=i32|i64|f64` (default: `f64`) to set valtype
+- `-O0` to disable opt
+- `-O1` (default) to enable basic opt (simplify insts, treeshake wasm imports)
+- `-O2` to enable advanced opt (inlining). unstable
+- `-O3` to enable advanceder opt (precompute const math). unstable
+- `-no-run` to not run wasm output, just compile
+- `-opt-log` to log some opts
+- `-code-log` to log some codegen (you probably want `-funcs`)
+- `-regex-log` to log some regex
+- `-funcs` to log funcs
+- `-ast-log` to log AST
+- `-opt-funcs` to log funcs after opt
+- `-sections` to log sections as hex
+- `-opt-no-inline` to not inline any funcs
+- `-tail-call` to enable tail calls (experimental + not widely implemented)
+- `-compile-hints` to enable V8 compilation hints (experimental + doesn't seem to do much?)

 - Little built-ins/prototype

 ## Performance
-*For the things it supports most of the time*, Porffor is *blazingly fast* compared to most interpreters, and common engines running without JIT. For those with JIT, it is usually slower by default, but can catch up with compiler arguments and typed input.

 ## Optimizations
 Mostly for reducing size. I do not really care about compiler perf/time as long as it is reasonable. We do not use/rely on external opt tools (`wasm-opt`, etc), instead doing optimization inside the compiler itself creating even smaller code sizes than `wasm-opt` itself can produce as we have more internal information.

 ## VSCode extension
 There is a vscode extension in `porffor-for-vscode` which tweaks JS syntax highlighting to be nicer with porffor features (eg highlighting wasm inside of inline asm).
