 # Building
 
+## Mint
+
 The Afterpay SDK uses [Mint][mint] to install and run Swift command line packages. This has been pre-compiled and included in the repository under the [`Tools/mint`][mint-directory] directory, meaning it does not need to be installed or managed externally.
 
 > **NOTE:** Mint will automatically download the packages it manages on demand. To speed up the initial build of the SDK, the packages can be downloaded by running the [`Scripts/bootstrap`][bootstrap] script.
 
-Building the project is as simple as cloning the repository, opening [`Afterpay.xcworkspace`][afterpay-workspace] and building the `Afterpay` target. The example project can be built and run via the `Example` target.
