 ### Implementation Details
 
 BDK extends the capabilities of [rust-miniscript](https://github.com/apoelstra/rust-miniscript) by introducing the concept of an *ExtendedDescriptor*: it represents a descriptor that contains one or more "derivable keys" like `xpubs` or `xprvs`
-and can be "derived" to a normal Descriptor by deriving every single one of its keys. It is currently called "StringDescriptor" in the code, because it's implemented as a wrapped `miniscript::Descriptor<String>`.

 ExtendedDescriptors are derived using a single index instead of a full derivation path: this is because normally most of the path is fixed and can be represented right after the xpub/xprv itself, and only the
-final index changes for each address. This is what's normally called a *DescriptorExtendedKey* in codebase, and it's the represented with a similar syntax to Bitcoin Core's, such as:
