+Zstandard Documentation
+=======================
+
+This directory contains material defining the Zstandard format,
+as well as detailed instructions to use `zstd` library.
+
+__`zstd_manual.html`__ : Documentation of `zstd.h` API, in html format.
+Unfortunately, Github doesn't display `html` files in parsed format, just as source code.
+For a readable display of html API documentation of latest release,
+use this link: [https://raw.githack.com/facebook/zstd/release/doc/zstd_manual.html](https://raw.githack.com/facebook/zstd/release/doc/zstd_manual.html) .
+
+__`zstd_compression_format.md`__ : This document defines the Zstandard compression format.
+Compliant decoders must adhere to this document,
+and compliant encoders must generate data that follows it.
+
+Should you look for resources to develop your own port of Zstandard algorithm,
+you may find the following resources useful :
+
+__`educational_decoder`__ : This directory contains an implementation of a Zstandard decoder,
+compliant with the Zstandard compression format.
+It can be used, for example, to better understand the format,
+or as the basis for a separate implementation of Zstandard decoder.
+
+[__`decode_corpus`__](https://github.com/facebook/zstd/tree/dev/tests#decodecorpus---tool-to-generate-zstandard-frames-for-decoder-testing) :
+This tool, stored in `/tests` directory, is able to generate random valid frames,
+which is useful if you wish to test your decoder and verify it fully supports the specification.
