Run docc preview TSPL.docc in this repository's root directory.

After running DocC, open the link that docc outputs to display a local preview in your browser.

Note:

If you installed DocC by downloading a toolchain from Swift.org, docc is located in usr/bin/, relative to the installation path of the toolchain. Make sure your shell's PATH environment variable includes that directory.

If you installed DocC by downloading Xcode, run xcrun docc preview TSPL.docc instead.
