+#### Available traits
+
+The Swift package manager now supports [traits][], which can be used to configure
+SQLite.swift for different use cases.
+
+  ```swift
+  dependencies: [
+    .package(url: "https://github.com/stephencelis/SQLite.swift.git", 
+             from: "0.15.4",
+             traits: ["XXX"])
+  ]
+  ```

+| Trait                    | Description                                       |
+|--------------------------|---------------------------------------------------|
+| `SystemSQLite` (default) | Uses the system SQLite (provided by Apple)        |
+| `SwiftToolchainCSQLite`  | Embeds the SQLite provided by [swift-toolchain][] |
+| `StandaloneSQLite`       | Only used by CocoaPods                            |
+| `SQLCipher`              | Embeds [SQLCipher][] (see below)                  |

 #### Using SQLite.swift with SQLCipher
 
 If you want to use [SQLCipher][] with SQLite.swift you can specify the `SQLCipher` trait when consuming SQLite.swift.

+## Installation
+
+On Linux you should enable the `SwiftToolchainCSQLite` trait to automatically
+embed SQLite:
+
+  ```swift
+  dependencies: [
+    .package(url: "https://github.com/stephencelis/SQLite.swift.git", 
+             from: "0.15.4",
+             traits: ["SwiftToolchainCSQLite"])
+  ]
+  ```
+
+See the [main documentation](Index.md#available-traits) for a list of all available traits.
