 # swift-dependency-updater
+
+The Swift Dependency Updater is a tool to automatically update dependencies of your swift package manager projects. Unlike `swift package update` it also checks if there are updates which require adjustments for the versions specified in the `Package.swift` file
+

+### [Mint](https://github.com/yonaskolb/mint)
+```
+mint install Nef10/swift-dependency-updater
+```
+
+### Swift Package Manager

+git clone https://github.com/Nef10/swift-dependency-updater.git
+$ cd swift-dependency-updater
+$ swift run swift-dependency-updater
+```
+
+## Usage
+
+### List all dependencies and possible updates:
+
+`swift-dependency-updater list [<folder>] [--exclude-indirect] [--updates-only]`
+
+### Help
+
+Run `swift-dependency-updater --help` for a full list of supported commands, and `swift-dependency-updater help <subcommand>` for detailed help on a specific command.
+
+## Inspiration
