+
+Nibbles of useful swift code that I regularaly use across various proejcts.
+
+## Getting Started
+
+To add `swift-nibbles` to your project, first add it as a dependency.
+
+```swift
+.package(url: "https://github.com/connor-ricks/swift-nibbles/", branch: "main")
+```
+
+Nibbles are all broken down into their own targets, so you can choose which nibbles are relevant to your project.
+
+```swift
+.product(name: "HTTPNetworking", package: "swift-nibbles")
+// or
+.product(name: "Cache", package: "swift-nibbles")
+```
+
+## Nibbles
+
+### 🗄️ Cache
+A simple cache that can be used to store objects.
+
+Use a cache to store objects of a given type in memory using an associated key.
+You can then fetch attempt to retrieve from the cache at a later time using the key.
+
+### ⛓️ Extensions
+A collection of useful extensions that I freqeuntly implement across multiple projects.
+
+### 🕸️ HTTPNetworking
+A client that creates and manages requests over the network.
+
+The client provides support for sharing common functionality across all requests, but each request can also layer on additional functionality if needed.
+
+Using the concept of plugins, you can customize your client's functionalities to your needs.
+
+- **Adaptors:** Mutate a `URLRequest` before it is dispatched over the network. Useful for adding headers or query parameters to outbound requests.
+- **Validators** Validate the `HTTPURLResponse` and `Data` of a `URLRequest` before decoding. Useful for checking status codes and other common validation stratagies. 
+- **Retriers** Retry failed requests on your terms.
+
+Generally an ``HTTPClient`` is used to manage the interaction with a single API service. Most APIs
+have their own nuance and complexities, and encapsulating all of that in one place can help structure your code in a
+more scalable and testable way.
+
+### 🏷️ Identified
+
+A protocol for marking objects as identified and allowing interaction with their identifiers in a type-safe way.
