+# Windows build
+
+The native Windows build uses MSYS2's UCRT64 toolchain and creates a runnable
+folder of PE executables plus their runtime DLLs and data files. It does not
+reuse the GNU/Linux `build/` directory or generated `config.mk`.
+
+Install MSYS2, then install the UCRT64 packages needed by the project:
+
+```sh
+pacman -S --needed \
+  mingw-w64-ucrt-x86_64-gcc \
+  mingw-w64-ucrt-x86_64-make \
+  mingw-w64-ucrt-x86_64-pkgconf \
+  mingw-w64-ucrt-x86_64-libsodium \
+  mingw-w64-ucrt-x86_64-curl \
+  mingw-w64-ucrt-x86_64-SDL2 \
+  mingw-w64-ucrt-x86_64-SDL2_ttf
+```
+
+From the repository root in PowerShell, run:
+
+```powershell
+.\build-windows.ps1
+```
+
+Compiler outputs, including tests and intermediate files, stay in
+`build\windows`. Distribution output is staged separately: `dist\windows-x64`
+contains only the eight user-facing programs, their runtime DLLs, assets,
+Scheme files, and manuals. `dist\installers` contains a portable ZIP and, when
+Inno Setup is installed, the setup executable. Do not distribute the contents
+of `build\windows` directly. The build date's Discordian calendar conversion
+is compiled into the GUI; no external `ddate` installation is needed.
+
+To create just the portable ZIP, run `build-windows.ps1`. To create the install
+wizard as well, run `build-windows-installer.ps1`.
+
+`cable-thang.exe` is a native C/S7 client using Cesspool and Sleep. Node.js
+and Cabal JavaScript modules are needed only for optional interoperability
+tests. Cable audio and video support are experimental and disabled by default,
+so the regular Windows build does not require FFmpeg. To enable both, install
+FFmpeg and build with:
+
+```powershell
+pacman -S --needed mingw-w64-ucrt-x86_64-ffmpeg
+.\build-windows.ps1 -EnableCableMedia
+```
+
+The UCRT64 FFmpeg libraries provide Cable's AAC-LC encoder/decoder, OBS MPEG-TS
+ingest, and low-resolution JPEG video exchange; their runtime DLLs are copied
+beside the Windows executables. In `cable-thang`, `OBS INPUT` (or
+Ctrl+Shift+V) listens on local UDP port 5000; OBS can publish MPEG-TS there
+using its Custom FFmpeg Output.
+
+The GNU/Linux workflow is `./configure`, `make`, and `make install`; its default
+compiler output is `build/linux`. To create a staged GNU/Linux tarball, use
+`make package`. Release artifacts go under `dist/` on both platforms. To create
+a source-only archive, run `package-source.ps1`; its contents and exclusions
+are documented in `docs\source-distribution.md`.
+That configuration checks for libcurl because the Dillo-compatible
+`dat-dns` lookup uses HTTPS `/.well-known/dat`; it does not call the operating
+system DNS TXT resolver.
+
+## Install wizard
+
+Install [Inno Setup 6](https://jrsoftware.org/isinfo.php) after installing the
+MSYS2 build tools. From PowerShell at the repository root, run:
+
+```powershell
+.\build-windows-installer.ps1
+```
+
+The script rebuilds the Windows applications, bundles their DLLs and runtime
+assets, and creates `dist\installers\dat-thang-setup-0.0.002-x64.exe`.
+The application identifies itself as `dat-thang v0.0.002 (prototype,
+pre-alpha)`; the executable file version is `0.0.2.0`.
+The wizard offers a per-user or all-users install, a destination folder,
+optional desktop shortcut, optional PATH entry for the terminal commands, and
+an optional launch at the end. Uninstall removes a PATH entry only when this
+installer added it. The app and installer use the same generic green hexagon
+icon. The Start menu includes dat-thang and a command prompt with the installed
+tools on PATH.
+
+`cable-thang.exe` is included for opening a room address from the command
+prompt and connects through Cesspool.
+
+`cesspool-bootstrap.exe` runs a dedicated Cesspool discovery node in the
+foreground. It is for an operator deploying a reachable public rendezvous
+host, not something chat users need to run. The node needs a stable state
+directory and inbound UDP on the selected port; see `docs\cesspool-bootstrap.1`
+for process-supervisor and firewall setup. The Windows installer includes the
+executable and the operator manpage in its `docs` folder.
+
+Keep the node identity outside the checkout. In PowerShell, run the development
+executable with `--state-dir "$env:LOCALAPPDATA\dat-gpt\cesspool-bootstrap-state"`.
+That keeps the private identity key in per-user application data rather than in
+the source tree or disposable compiler output.
