 The workflow includes statements which print the working directory
 and list the contents of that directory at various points in the installation.
 We do that so that it's easier to infer a valid choice of directory structure for building RandLAPACK.
+
+## 6. Native Windows (MSVC)
+
+RandLAPACK builds natively on Windows with MSVC (Visual Studio 2022) and
+Intel oneMKL using ILP64, sequential linking. The easy path, from a
+"Developer PowerShell for VS 2022" prompt in the repository root:
+
+```powershell
+.\install\install.ps1
+```
+
+This builds all dependencies (oneMKL through vcpkg, or pass
+`-MklRoot <path>` to use an existing oneAPI install), then builds, installs,
+and tests RandLAPACK, mirroring `install.sh`'s directory layout. The header
+comment in `install.ps1` documents the options.
+
+Points worth knowing:
+
+- **ILP64 is required.** RandBLAS's MKL sparse backend checks at compile time
+  that its 64-bit indices match `MKL_INT`, so BLAS++ must be configured with
+  `-Dblas_int=ilp64` against `mkl_intel_ilp64_dll.lib` (the installer does
+  this for you).
+- **BLAS++/LAPACK++ come from BallisticLA branches** (`BallisticLA/blaspp@remove-symv-debug-print`,
+  `BallisticLA/lapackpp@msvc-direct-includes`) until two one-line MSVC fixes
+  merge upstream (blaspp PR #132, lapackpp PR #87).
+- **OpenMP on MSVC uses the `/openmp:llvm` runtime**, selected automatically
+  by RandBLAS's build system — the only MSVC mode that accepts RandLAPACK's
+  64-bit loop indices and `collapse` clauses. Serial builds (OpenMP off) are
+  also fully functional.
+- **GPU support is not available on native Windows.**
+- Executables that link MKL need the MKL `bin` directory on `PATH` at run
+  time; the installer prints the path to keep.
+
+CI runs this configuration on every pull request (`core-windows` workflow);
+`.github/scripts/windows/run-ci.ps1 -Task Core -SetupDependencies` reproduces
+that job locally.

 # Using RandLAPACK's Automated Install Script
 
+The installer scripts live in the `install/` directory (`install/install.sh`
+for Linux/macOS, `install/install.ps1` for native Windows); a small wrapper is
+kept at the repository root so `bash install.sh` keeps working.

 This guide explains how to use the `install.sh` script to automatically install
 RandLAPACK and all of its dependencies (BLAS++, LAPACK++, Random123) with a
 single command.

+# RandLAPACK's GitHub CI
+
+Four workflows run on every push and pull request. They divide into two
+lanes per operating system: the **core** workflows hand-replicate the build
+recipe step by step (so a failure points at a specific step), and the
+**install-script** workflow runs the user-facing installers end to end (so
+the thing we tell users to type is itself under test).
+
+| Workflow | Job | Runner | Validates | Required check? |
+|----------|-----|--------|-----------|-----------------|
+| core-linux | `build` | ubuntu-latest | Release build + tests, extras build + tests, benchmark compile (OpenBLAS) | **yes** (`build`) |
+| core-linux | `build-asan` | ubuntu-latest | Debug + AddressSanitizer build and test run | no |
+| core-macos | `build` | macos-latest | same as Linux `build`, on Apple's toolchain | **yes** (`build`) |
+| core-macos | `build-asan` | macos-latest | Debug + AddressSanitizer build and test run | no |
+| core-windows | `build-windows` | windows-2022 | MSVC + oneMKL (ILP64, sequential) build + tests, serial (no OpenMP) | no (new) |
+| install-script | `install-linux` | ubuntu-latest | `install.sh`: fresh install, idempotent re-run, dependency-discovery path | **yes** |
+| install-script | `install-macos` | macos-latest | `install.sh`: fresh install, idempotent re-run | **yes** |
+| install-script | `install-windows` | windows-2022 | `install/install.ps1`: fresh install, idempotent re-run | no (new) |
+
+Required-check names match **job** names (`build`, `install-linux`,
+`install-macos`), not "workflow / job" display names. The two Windows jobs
+and the two `build-asan` jobs are deliberately not required yet; they become
+candidates once they have a green track record.
+
+## Things that are deliberate (do not "fix" without reading this)
+
+- **core-macos is red on purpose.** `TestQB.Polynomial_Decay_general1` fails
+  on Apple Silicon because Apple's default (old) Accelerate LAPACK has a
+  broken divide-and-conquer `gesdd`. The failure is kept as a canary: when
+  the planned migration to the new Accelerate interface happens, this test
+  flipping green is the evidence the bug is gone. A local fix exists
+  (reference SVD via `gesvd`) but is intentionally unmerged.
+- **The RandBLAS submodule's own tests do not run here**
+  (`-DBUILD_TESTS=OFF` in the core recipes). The pinned commit is already
+  tested by RandBLAS's CI; rebuilding its ~450 tests in every RandLAPACK job
+  roughly doubled job times. The install-script lanes keep them, preserving
+  exactly what a user's install builds.
+- **Windows builds are serial (OpenMP off) for now.** RandLAPACK's OpenMP
+  loops need MSVC's `/openmp:llvm` runtime (64-bit indices, `collapse`),
+  which RandBLAS's build system does not select yet; see BallisticLA/RandBLAS#184.
+  When that lands, core-windows grows an OpenMP leg.
+- **BLAS++ and LAPACK++ on Windows come from BallisticLA fork branches**
+  (`BallisticLA/blaspp@remove-symv-debug-print`,
+  `BallisticLA/lapackpp@msvc-direct-includes`) carrying two one-line MSVC
+  fixes. Upstream PRs are open (blaspp #132, lapackpp #87); once merged, the
+  clones in `.github/actions/setup-randlapack-deps-windows/setup.ps1` move
+  back to upstream master.
+
+## Caches
+
+Dependencies (BLAS++, LAPACK++, Random123 — plus oneMKL and GoogleTest on
+Windows) are built once and cached; a cache-miss run is several minutes
+slower than a warm one.
+
+| Cache key prefix | Used by | Lives beside |
+|------------------|---------|--------------|
+| `core-deps-<OS>-v<N>` | core-linux, core-macos (both jobs) | the workspace (`../*-install`) |
+| `installer-deps-<OS>-v<N>` | install-linux | `deps-install/` in the workspace |
+| `windows-*-v<N>` (five keys) | core-windows, install-windows | `..\windows-deps` |
+
+To force a rebuild against fresh upstream clones, bump the `-v` suffix in
+the relevant key. The Windows keys are additionally salted with a hash of
+`setup.ps1`, so editing that script invalidates them automatically.
+BLAS++/LAPACK++ track upstream default branches, so a stale cache also
+means frozen upstream — bump the suffix when upstream matters.
+
+## Reproducing CI locally
+
+- Linux/macOS core recipe: follow the steps in the workflow file; they are
+  ordinary `cmake` + `make` invocations.
+- Installer lanes: `bash install.sh --yes --no-gpu` from a fresh clone.
+- Windows (from an MSVC developer prompt in the repository root):
+  `.github\scripts\windows\run-ci.ps1 -Task Core -SetupDependencies`
+  reproduces core-windows; `.\install\install.ps1` reproduces
+  install-windows.
