-## Design
+## Usage
 
-The data layout design is very simple. It consists of data split into chunks
-with the first chunk holding the metadata for the structure and files.

-
-```

-Magic string to detect if the read file is what we expect it is.
-Represented in 3 bytes.

-Value is `0x514D21`, the closest approximation of "Sindri".

-Version of the specification.
-Represented in `2 bytes`.
-
-Value is `1` currently.
-
-#### Compression
-
-Wether LZ4 compression is enabled/disabled.
-Represented in `1 byte`.

-#### File
-
-Piece of data stored, consisting of 3 parts:

-
-##### Path
-
-Path of the file as if it were on the filesystem.
-Represented in `512 bytes`.
-
-##### Offset
-
-The offset to the file, starting from the true 0th byte of the first chunk.
-Represented in `8 bytes`.
