-# Advent of Code Swift Starter Project
+# Advent of Code 2023 Solutions
 
-[![Language](https://img.shields.io/badge/language-Swift-red.svg)](https://swift.org)
-
-Daily programming puzzles at [Advent of Code](<https://adventofcode.com/>), by
-[Eric Wastl](<http://was.tl/>). This is a small example starter project for
-building Advent of Code solutions.
-
-## Usage
-
-Swift comes with Xcode, or you can [install it](https://www.swift.org/install/)
-on a supported macOS, Linux, or Windows platform. 
-
-If you're using Xcode, you can open this project by choosing File / Open and
-select the parent directory. 
-
-If you prefer the command line, you can run the test suite with `swift test`,
-and run the output with `swift run`.
-
-If you're using Visual Studio Code to edit, you might find these Swift
-extensions useful:
-
-- [Swift](https://marketplace.visualstudio.com/items?itemName=sswg.swift-lang)
-  (provides core language edit / debug / test features)
-- [apple-swift-format](https://marketplace.visualstudio.com/items?itemName=vknabel.vscode-apple-swift-format)
-  (supports the [swift-format](https://github.com/apple/swift-format) package)
-
-## Challenges
+By Jim Wallace. These are rough, unpolished first passes as time allows.  
 
-The challenges assume three files (replace 00 with the day of the challenge).
+## Advent of Code Swift Starter Project
 
-- `Data/Day00.txt`: the input data provided for the challenge
-- `Sources/Day00.swift`: the code to solve the challenge
-- `Tests/Day00.swift`: any unit tests that you want to include
-
-To start a new day's challenge, make a copy of these files and update as
-necessary. The `AdventOfCode.swift` file controls which day's challenge is run
-with `swift run`. By default that runs the most recent challenge in the package.
-
-To supply command line arguments use `swift run AdventOfCode`. For example,
-`swift run -c release AdventOfCode --benchmark 3` builds the binary with full
-optimizations, and benchmarks the challenge for day 3.
-
-## Linting and Formatting
-
-Challenge source code can be linted and formatted automatically using the
-included dependency on `swift-format`.
-
-Lint source code with the following command:
-
-```shell
-$ swift package lint-source-code
-```
-
-Format source code with the following command:
-
-```shell
-$ swift package format-source-code
-Plugin ‘Format Source Code’ wants permission to write to the package directory.
-Stated reason: “This command formats the Swift source files”.
-Allow this plugin to write to the package directory? (yes/no)
-```
+[![Language](https://img.shields.io/badge/language-Swift-red.svg)](https://swift.org)
 
-To avoid the interactive prompt when formatting source code, use the 
-`--allow-writing-to-package-directory` flag.
-
-```shell
-$ swift package format-source-code --allow-writing-to-package-directory
-```

-swift-format will use the built-in default style to lint and format code. A
-`.swift-format` configuration file can be used to customize the style used, see
-[Configuration](https://github.com/apple/swift-format/blob/main/Documentation/Configuration.md)
-for more details.
