+A plugin for [swift-snapshot-testing](https://github.com/pointfreeco/swift-snapshot-testing) that combines it with [swift-custom-dump](https://github.com/pointfreeco/swift-custom-dump/) to be able to produce textual snapshots of model objects.
+
+### Usage
+
+Swift Package Manager
+
+If you want to use SnapshotTesting in any other project that uses SwiftPM, add the package as a dependency in Package.swift:
+
+```
+dependencies: [
+  .package(
+    url: "https://github.com/tahirmt/swift-snapshot-testing-dump",
+    from: "1.0.0"
+  ),
+]
+```
+Next, add `SnapshotTestingDump` as a dependency of your test target:
+
+```
+targets: [
+  .target(name: "MyApp"),
+  .testTarget(
+    name: "MyAppTests",
+    dependencies: [
+      "MyApp",
+      .product(name: "SnapshotTestingDump", package: "swift-snapshot-testing-dump"),
+    ]
+  )
+]
+```
