 # libWiiPy
 libWiiPy is a modern Python 3 library for handling the various files and formats found on the Wii. It aims to be simple to use, well maintained, and offer as many features as reasonably possible in one library, so that a newly-written Python program could do 100% of its Wii-related work with just one library. It also aims to be fully cross-platform, so that any tools written with it can also be cross-platform.
 
-libWiiPy is inspired by [libWiiSharp](https://github.com/TheShadowEevee/libWiiSharp), which was originally created by `Leathl` and is now maintained by [@TheShadowEevee](https://github.com/TheShadowEevee).

 She made the very cool banner you can see at the top of this README, and has also helped greatly with my sanity throughout debugging this library.

 This module exposes functions for both packing and unpacking U8 archives, as well as code to parse IMET headers. IMET headers are a header format used specifically for U8 archives containing the banner of a channel, as they store the localized name of the channel along with other banner metadata.

 # libWiiPy.title.title Module
 
-## Description
-
 The `libWiiPy.title.title` module provides a high-level interface for handling all the components of a digital Wii title through one class. It allows for directly importing a WAD, and will automatically extract the various components and load them into their appropriate classes. Additionally, it provides duplicates of some methods found in those classes that require fewer arguments, as it has the context of the other components and is able to retrieve additional data automatically.
 
 An example of that idea can be seen with the method `get_content_by_index()`. In its original definition, which can be seen at <project:#libWiiPy.title.content.ContentRegion.get_content_by_index>, you are required to supply the Title Key for the title that the content is sourced from. In contrast, when using <project:#libWiiPy.title.title.Title.get_content_by_index>, you do not need to supply a Title Key, as the Title object already has the context of the Ticket and can retrieve the Title Key from it automatically. In a similar vein, this module provides the easiest route for verifying that a title is legitimately signed by Nintendo. The method <project:#libWiiPy.title.title.Title.get_is_signed> is able to access the entire certificate chain, the TMD, and the Ticket, and is therefore able to verify all components of the title by itself.
