-# cuda-oxide Dev Container
-
-This dev container provides the toolchain expected by cuda-oxide:
-
-- Ubuntu 24.04
-- CUDA Toolkit 13.0
-- LLVM 21 with NVPTX support
-- Clang 21 resource headers for `bindgen`
-- Rust `nightly-2026-08-28` with `rust-src`, `rustc-dev`, `rust-analyzer`,
-  `rustfmt` and `clippy`. `llvm-tools` is not preinstalled in the image;
-  rustup adds it on your first cargo command in the checkout, because
-  `rust-toolchain.toml` names it. The image ships LLVM 21 and
-  `CUDA_OXIDE_LLC` already points at `llc-21`, so nothing waits on it.
-
-Open the repository in a devcontainer-aware editor and choose "Reopen in
-Container". The container requests GPU access with `--gpus=all` and uses
-`updateRemoteUserUID` so generated Cargo artifacts and exported PTX files stay
-writable from the host checkout.
-
-Inside the container:
-
-```bash
-cargo oxide doctor
-cargo oxide run vecadd
-```
-
-The CUDA Toolkit is provided by the container image; it does not need to be
-installed on the host. The host must provide an NVIDIA GPU, a driver compatible
-with CUDA 13.0, and the NVIDIA Container Toolkit so Docker can expose the GPU
-to the container.
-
-If the host driver is too old, GPU commands such as `nvidia-smi`,
-`cargo oxide doctor`, or `cargo oxide run vecadd` will fail inside the
-container. Update the host NVIDIA driver rather than installing a different
-CUDA Toolkit in the container.
-
-The image does not set `LD_LIBRARY_PATH`; the NVIDIA Container Toolkit should
-provide the host driver libraries at runtime.

+# cuda-oxide Dev Container
+
+This dev container provides the toolchain expected by cuda-oxide:
+
+- Ubuntu 24.04
+- CUDA Toolkit 13.0
+- LLVM 21 with NVPTX support
+- Clang 21 resource headers for `bindgen`
+- Rust `nightly-2026-08-28` with `rust-src`, `rustc-dev`, `rust-analyzer`,
+  `rustfmt` and `clippy`. `llvm-tools` is not preinstalled in the image;
+  rustup adds it on your first cargo command under `cuda-oxide/`, because
+  `cuda-oxide/rust-toolchain.toml` names it. The image ships LLVM 21 and
+  `CUDA_OXIDE_LLC` already points at `llc-21`, so nothing waits on it.
+
+Open the repository's `cuda-oxide/` folder in a devcontainer-aware editor and
+choose "Reopen in Container". For example, run `code cuda-oxide` from the
+repository root. The editor discovers `cuda-oxide/.devcontainer/devcontainer.json`.
+The container requests GPU access with `--gpus=all` and uses
+`updateRemoteUserUID` so generated Cargo artifacts and exported PTX files stay
+writable from the host checkout.
+
+The whole repository is mounted at `/workspaces/cuda-rust`, including the shared
+host crates next to `cuda-oxide/`. The editor and commands start in
+`/workspaces/cuda-rust/cuda-oxide`. The checkout directory on the host can have
+any name. The Docker build context is only `.devcontainer/`; repository files
+are mounted when the container starts, rather than copied into the image.
+
+For CLI usage, run these commands from the repository root:
+
+```bash
+npx -y @devcontainers/cli up \
+  --workspace-folder ./cuda-oxide \
+  --config ./cuda-oxide/.devcontainer/devcontainer.json
+npx -y @devcontainers/cli exec \
+  --workspace-folder ./cuda-oxide \
+  --config ./cuda-oxide/.devcontainer/devcontainer.json cargo oxide doctor
+npx -y @devcontainers/cli exec \
+  --workspace-folder ./cuda-oxide \
+  --config ./cuda-oxide/.devcontainer/devcontainer.json cargo oxide run vecadd
+```
+
+Inside an editor terminal in the container, run:
+
+```bash
+cargo oxide doctor
+cargo oxide run vecadd
+```
+
+The CUDA Toolkit is provided by the container image; it does not need to be
+installed on the host. The host must provide an NVIDIA GPU, a driver compatible
+with CUDA 13.0, and the NVIDIA Container Toolkit so Docker can expose the GPU
+to the container.
+
+If the host driver is too old, GPU commands such as `nvidia-smi`,
+`cargo oxide doctor`, or `cargo oxide run vecadd` will fail inside the
+container. Update the host NVIDIA driver rather than installing a different
+CUDA Toolkit in the container.
+
+The image does not set `LD_LIBRARY_PATH`; the NVIDIA Container Toolkit should
+provide the host driver libraries at runtime.
