+## Description
+
+`compress.zstd` is a module that assists in the compression and
+decompression of binary data using `zstd` compression.
+
+## Examples
+
+Decode a `.zst` file from disk:
+
+```v
+import os
+import compress.zstd
+
+fn main() {
+	compressed := os.read_bytes('document.zst') or { panic(err) }
+	decompressed := zstd.decompress(compressed) or { panic(err) }
+	println(decompressed.bytestr())
+}
+```
+
+For a runnable example in this repository, see
+[examples/read_zstd_file.v](examples/read_zstd_file.v).
+
+`read_zstd_files_test.v` is a test file. Run it with
+`v test read_zstd_files_test.v`, not with `v read_zstd_files_test.v`.
