            ## Install

            ### Recommended — npm (one command, both binaries)

            ```bash
            npm install -g deepseek-tui
            ```

            The wrapper downloads both binaries from this Release and places them in the same directory.

            ### Docker / GHCR

            ```bash
            docker run --rm -it \
              -e DEEPSEEK_API_KEY="$DEEPSEEK_API_KEY" \
              -v ~/.deepseek:/home/deepseek/.deepseek \
              ghcr.io/hmbown/deepseek-tui:${{ steps.release_tag.outputs.tag }}
            ```

            The image ships the `deepseek` dispatcher and `deepseek-tui` runtime. The `latest` tag is also updated on release.

            ### Cargo (Linux / macOS)

            ```bash
            cargo install deepseek-tui-cli deepseek-tui --locked
            ```

            Both crates are required — `deepseek-tui-cli` produces the `deepseek` dispatcher and `deepseek-tui` produces the interactive runtime that the dispatcher delegates to. Installing only one binary will fail at runtime with a `MISSING_COMPANION_BINARY` error.

            ### Manual download

            **Both** binaries below must be downloaded for your platform and dropped into the same directory (e.g. `~/.local/bin/`):

            | Platform | Dispatcher | TUI runtime |
            |---|---|---|
            | Linux x64 | `deepseek-linux-x64` | `deepseek-tui-linux-x64` |
            | Linux ARM64 | `deepseek-linux-arm64` | `deepseek-tui-linux-arm64` |
            | macOS x64 | `deepseek-macos-x64` | `deepseek-tui-macos-x64` |
            | macOS ARM | `deepseek-macos-arm64` | `deepseek-tui-macos-arm64` |
            | Windows x64 | `deepseek-windows-x64.exe` | `deepseek-tui-windows-x64.exe` |

            Then `chmod +x` both (Unix) and run `./deepseek`.

            ### Verify (recommended)

            Download `deepseek-artifacts-sha256.txt` from this Release and verify:

            ```bash
            # Linux
            sha256sum -c deepseek-artifacts-sha256.txt

            # macOS
            shasum -a 256 -c deepseek-artifacts-sha256.txt
            ```

            ## Changelog

            See [CHANGELOG.md](https://github.com/Hmbown/DeepSeek-TUI/blob/main/CHANGELOG.md) for the full notes for this release.

# npm publish is intentionally not automated. The npm account requires 2FA OTP
# on every publish, and a granular automation token that bypasses 2FA has not
# been provisioned. Release the npm wrapper manually from a developer machine
# after the GitHub Release has been created — see CLAUDE.md "Releases" for the
# exact commands.
