+## Requisites
+
+**realpath** is a **Windows-only** program (implemented in [**realpath.cpp**](./realpath.cpp)) and depends on:
+
+* [**STLSoft**](https://github.com/synesissoftware/STLSoft) (1.11+) - **WinSTL** absolute-path and error-description components;
+
+
+## Building
+
+
+### via CMake
+
+The primary choice for installation is by use of **CMake** on Windows.
+
+1. Obtain the latest distribution of **realpath**, from
+   https://github.com/sistools/realpath/, e.g.
+
+    ```bash
+    $ mkdir -p ~/open-source
+    $ cd ~/open-source
+    $ git clone https://github.com/sistools/realpath/
+    ```
+
+2. Prepare the CMake configuration, via the **prepare_cmake.sh** script, as
+   in:
+
+    ```bash
+    $ cd ~/open-source/realpath
+    $ ./prepare_cmake.sh
+    ```
+
+   (**NOTE**: configuring on a non-Windows host fails: the tool targets
+   Windows only.)
+
+3. Run a build of the generated **CMake**-derived build files via the
+   **build_cmake.sh** script, as in:
+
+    ```bash
+    $ cd ~/open-source/realpath
+    $ ./build_cmake.sh
+    ```
+
+   (**NOTE**: if you provide the flag `--run-make` (=== `-m`) in step 2 then you do
+   not need this step.)
+
+4. As a check, execute the built program, as in:
+
+    ```bash
+    $ cd ~/open-source/realpath
+    $ ./_build/realpath --help
+    ```
+
+5. Finally, if you wish to do so, you can install the tool on the host, via `cmake`, as in:
+
+    ```bash
+    $ cd ~/open-source/realpath
+    $ cmake --install ./_build --config Release
+    ```
+
+
+## Requisites
+
+**realpath** requires:
+
+* [**STLSoft**](https://github.com/synesissoftware/STLSoft), version 1.11.1
+  or later;
+* CMake 3.20 or later;
+* a Windows C/C++ toolchain supported by CMake.
+
+
+## Building
+
+The primary build method is CMake. From PowerShell:
+
+```powershell
+git clone https://github.com/sistools/realpath.git
+Set-Location realpath
+cmake -S . -B _build
+cmake --build _build --config Release
+```
+
+The resulting executable is `_build/Release/realpath.exe`.
+
+
+## Installing
+
+To install into a user-local directory:
+
+```powershell
+cmake --install _build --config Release --prefix "$env:LOCALAPPDATA\Programs\realpath"
+```
+
+The installed executable is placed in the `bin` directory beneath the
+selected prefix.
+
+
+## Testing
+
+Configure the project with `-DBUILD_TESTING=ON` to build its tests, then run:
+
+```powershell
+ctest --test-dir _build -C Release --output-on-failure
+```

+## Introduction
+
+**realpath** is a Windows-only command-line program implemented in
+[**realpath.cpp**](./realpath.cpp). It uses the **STLSoft** / **WinSTL**
+libraries to provide Windows path and error-description facilities.
+
+
+## Build requirements
+
+
+### STLSoft
+
+**STLSoft** version **1.11.1** or later is required. It may be supplied to
+CMake in either of the following ways:
+
+* install a CMake package that can be found by `find_package(STLSoft)`;
+* pass the STLSoft root directory with `-DSTLSOFT=<directory>`; or
+* set the `STLSOFT` environment variable to the STLSoft root directory.
+
+The root directory must contain the STLSoft `include` directory.
+
+
+### CMake
+
+**CMake** version **3.20** or later is required. The default C++ language
+standard is C++17; this can be changed when configuring the project with the
+**prepare_cmake.sh** helper.
+
+
+### Windows C/C++ toolchain
+
+A Windows C/C++ toolchain supported by **CMake** is required. The project
+supports the toolchains and generators available to the installed CMake,
+including Visual C++ and MinGW where configured.
+
+
+## Optional requirements
+
+
+### Doxygen
+
+**Doxygen** is required only when generating the API documentation with
+**generate_doxygen.cmd**. The `doxygen` executable must be available on
+`PATH`, and the CMake build directory must contain the generated `Doxyfile`.
