+For user manual as well as API documentation, check: https://harfbuzz.github.io
+
+## Download
+
+For tarball releases of HarfBuzz, look [here][3]. At the same place you
+will also find Win32/Win64 binary bundles that include `libharfbuzz` DLL,
+`hb-view.exe`, `hb-shape.exe`, and all dependencies.
+
+The canonical source tree is available on [github][4].
+
+The API that comes with `hb.h` will not change incompatibly. Other, peripheral,
+headers are more likely to go through minor modifications, but again, we do our
+best to never change API in an incompatible way. We will never break the ABI.
+
+If you are not sure whether Pango or HarfBuzz is right for you, read [Pango vs
+HarfBuzz][5].
+
+## Development
+
For build information, see [BUILD.md](BUILD.md).
For custom configurations, see [CONFIG.md](CONFIG.md).
-For test execution, see [TESTING.md](TESTING.md).
+For testing and profiling, see [TESTING.md](TESTING.md).
+
+To get a better idea of where HarfBuzz stands in the text rendering stack you

+years old. Here are a few presentation slides about HarfBuzz at the
+Internationalization and Unicode Conference over the years:

+* November 2014, [Unicode, OpenType, and HarfBuzz: Closing the Circle][7],
+* October 2012, [HarfBuzz, The Free and Open Text Shaping Engine][8],
+* October 2009, [HarfBuzz: the Free and Open Shaping Engine][9].

+
+## Name
+
+HarfBuzz (حرف‌باز) is my Persian translation of “[OpenType][1]”,
+transliterated using the Latin script. It sports a second meaning, but that
+ain’t translatable.
+
+> Background: Originally there was this font format called TrueType. People and
+> companies started calling their type engines all things ending in Type:
+> FreeType, CoolType, ClearType, etc. And then came OpenType, which is the
+> successor of TrueType. So, for my OpenType implementation, I decided to stick
+> with the concept but use the Persian translation. Which is fitting given that
+> Persian is written in the Arabic script, and OpenType is an extension of
+> TrueType that adds support for complex script rendering, and HarfBuzz is an
+> implementation of OpenType complex text shaping.
