## What it is
A meta-repository of RISC-V development tools that bundles the Spike ISA simulator, riscv-tests, riscv-opcodes, and the riscv-pk proxy kernel/boot loader, with a build script that assembles a riscv64 toolchain via crosstool-ng. It serves as a one-stop quickstart for building and testing software against the RISC-V instruction set.

## Use cases
- simulate RISC-V binaries on x86 hardware
- run RISC-V ISA compliance tests
- build a riscv64-unknown-elf cross-compiler toolchain
- boot a Linux kernel on a RISC-V simulator
- look up RISC-V opcode encodings
- set up a RISC-V development environment from scratch

## When to choose
- you need an all-in-one quickstart for RISC-V simulation and testing
- you want Spike, riscv-tests, and pk built together with one script
- you are doing low-level RISC-V ISA or bare-metal development

## When to avoid
- you only need a cross-compiler, which distro packages provide directly
- you want actively developed individual tools - use the upstream repos like riscv-isa-sim
- you need a production RISC-V toolchain rather than a reference build
