 With our pallet now compiling and passing it's tests, we're ready to add it to our node.

 We first add our newly-created crate as a dependency in the node's runtime Cargo.toml. Then we tell the pallet to only build its std feature when the runtime itself does, as follows:

 Next we will update `my-node/runtime/src/lib.rs` to actually use our new runtime pallet, by adding a trait implementation with our pallet_did and add it in our construct_runtime! macro.
