 This is my experiments to learn Zig. Might amount to something. Might not.
 
+A library and application to decompress or view squashfs archives.
+
 ## Current State
 
 Overall works, but currently is completely single threaded and is missing some features. Extraction is slow. Only properly work on Linux, any other OSes probably won't work fully.
+
+## Build options
+
+> `-Duse_c_libs`
+
+Instead of using Zig's standard library for decompression 
+
+> `Dversion`
+
+Sets the version of `unsquashfs` shown when `--version` is passed.
+
+## Capabilities
+
+Most features are present except for the following:
+
+* mod_time is not set on extraction
+* xattrs are not applied on extraction
+* Only zstd c library is implemented (all others result in error.TODO).
+* When using Zig decompression libraries then lzo and lz4 compression types are unavailable. I don't _really_ plan on spending the time to find and validate a library since neither is popular.
