+
+To use the Typescript SDK, at the root of this repository, run:
+
+```sh
+npm ci && npm run build && npm run pack
+```
+
+Which will produce a `.tgz` file that can be installed using npm or any other package manager like:
+
+```sh
+npm install /path/to/example-liquidity-layer/wormhole-foundation-example-liquidity-layer-solana-0.0.1.tgz
+```
+
+Once installed, it can be used like any other package:
+
+
+```ts
+
+// ...
+import * as tokenRouterSdk from "@wormhole-foundation/example-liquidity-layer-solana/tokenRouter";
+import { LiquidityLayerDeposit, LiquidityLayerMessage } from "@wormhole-foundation/example-liquidity-layer-solana/common";
+import { PreparedOrder } from "@wormhole-foundation/example-liquidity-layer-solana/tokenRouter/state";
+// ...
+
+```
