+# ZSTD Contrib Library Manual
+
+
+## Introduction
+
+ZSTD on ZFS uses a heavily cut down, but otherwise unmodified version of ZSTD.
+This `contrib` contains the  unmodified ZSTD library, please do not edit these files.
+
+## Updating ZSTD
+
+To update ZSTD the following steps need to be taken:
+
+1.  Download the latest archive of ZSTD
+2. Replace (not merge): `common`, `compress`, `decompress` and `zstd.h` with the new version from the `lib` folder in the downloaded archive of zstd.
+3. Make sure any newly requered files and/or folders are also included.
+ A. Make sure new folders are listed in: `configure.ac`
+ B. Make sure new Files And Folder are listed in: `lib/libzstd/Makefile.am` and `module/zstd/Makefile.in`
+ C. Make sure any relevant File and Folders are listed in this Readme
+4.  Make sure to change `ZFS_MODULE_VERSION("1.4.4")` in `module/zstd/zstd.c`

+\fBzstd\fR is a high-performance compression algorithm that features a
+combination of high compression ratios and high speed.
+Compared to \fBgzip\fR, \fBzstd\fR offers slighty better compression at much
+higher speeds.
+Compared to \fBlz4\fR, \fBzstd\fR offers much better compression while being
+only modestly slower.
+Typically, \fBzstd\fR compression speed ranges from 250 - 500
+megabytes/second/thread, and decompression speed is over 1
+gigabyte/second/thread.
+Booting off of \fBzstd\fR-compressed root pools is not yet supported.
+
+When the \fBzstd\fR feature is set to \fBenabled\fR, the administrator can turn
+on \fBzstd\fR compression of any dataset by running
+`zfs set compress=zstd <pool/fs>`.
+This feature becomes \fBactive\fR once a \fBcompress\fR property has been set to
+\fBzstd\fR, and will return to being \fBenabled\fR once all filesystems that
+have ever had their compress property set to \fBzstd\fR are destroyed.
