+# vgmstream
+This is vgmstream, a library for playing streamed (prerecorded) video game audio.
+
+Some of vgmstream's features:
+- [Hundreds of video game music formats and codecs](doc/FORMATS.md), from typical game engine files
+  to obscure single-game codecs, aiming for high accuracy and compatibility.
+- Support for looped BGM, using file's internal metadata for smooth transitions, with accurate
+  sample counts.
+- [Subsongs](doc/USAGE.md#subsongs), playing a format's multiple internal songs separately.
+- Many types of companion files (data split into multiple files) and custom containers.
+- Encryption keys, internal stream names, and many other unusual cases found in game audio.
+- [TXTH](doc/TXTH.md) function, to add external support for extra formats, including raw audio in
+  many forms.
+- [TXTP](doc/TXTP.md) function, for real-time and per-file config, like forced looping, removing
+  channels, playing certain subsong, or fusing multiple files into a single one.
+- Simple [external tagging](doc/USAGE.md#tagging) via .m3u files.
+- [Plugins](#getting-vgmstream) are available for various media player software and operating systems.

+
+## Getting vgmstream
+There are multiple end-user components:
+- [vgmstream-cli](doc/USAGE.md#testexevgmstream-cli-command-line-decoder): A command-line decoder.
+- [in_vgmstream](doc/USAGE.md#in_vgmstream-winamp-plugin): A Winamp plugin.
+- [foo_input_vgmstream](doc/USAGE.md#foo_input_vgmstream-foobar2000-plugin): A foobar2000 component.
+- [xmp-vgmstream](doc/USAGE.md#xmp-vgmstream-xmplay-plugin): An XMPlay plugin.
+- [vgmstream.so](doc/USAGE.md#audacious-plugin): An Audacious plugin.
+- [vgmstream123](doc/USAGE.md#vgmstream123-command-line-player): A command-line player.
+
+The main library (plain *vgmstream*) is the code that handles the internal conversion, while the
+above components are what you use to get sound.
+
+If you want to convert game audio to `.wav`, try getting *vgmstream-cli* (see below) then
+drag-and-drop one or more files to the executable (support may vary per O.S. or distro).
+This should create `(file.extension).wav`, if the format is supported. More user-friendly
+would be installing a player like *foobar2000* (for Windows) or *Audacious* (for Linux)
+and the vgmstream plugin. Then you can directly listen your files and set options like infinite
+looping, or convert to `.wav` with the player's options (also easier if your file has multiple
+"subsongs").
+
+See [components](doc/USAGE.md#components) in the *usage guide* for full install instructions and
+explanations. The aim is feature parity, but there are a few differences between them due to
+missing parts on vgmstream's side or lack of support in the player.
+
+Note that vgmstream cannot *encode* (convert from `.wav` to a video game format), it only *decodes*
+(plays game audio).
+
+
+### Windows
+Get the latest prebuilt binaries (CLI/plugins/etc) on our website:
+- https://vgmstream.org
+
+Or the less frequent "official" releases on GitHub:
+- https://github.com/vgmstream/vgmstream/releases
+
+The foobar2000 component is also available on https://www.foobar2000.org based on current
+release.
+
+If the above links fail, you may also try the alternative versions built by
+[bnnm](https://github.com/bnnm):
+- https://github.com/bnnm/vgmstream-builds/raw/master/bin/vgmstream-latest-test-u.zip
+
+You may compile from source as well, see the [build guide](doc/BUILD.md).
+
+### Linux
+A prebuilt CLI binary is available. It's statically linked and should work on systems running
+Linux kernel v3.2 and above:
+- https://vgmstream.org
+- https://github.com/vgmstream/vgmstream/releases
+
+Building from source will also give you *vgmstream.so* (Audacious plugin), and *vgmstream123*
+(command-line player).
+
+When building, many extra components have to be installed or compiled separately, which the
+[build guide](doc/BUILD.md) describes in detail. For a quick build on Debian and Ubuntu-style
+distributions run `./make-build-cmake.sh`. The script will need to install various dependencies,
+so you may prefer to copy commands and run them manually.
+
+### macOS
+A prebuilt CLI binary is available as well:
+- https://vgmstream.org
+- https://github.com/vgmstream/vgmstream/releases
+
+Otherwise follow the [build guide](doc/BUILD.md).
