+### Install via NPM to import contracts
+To create a new project with TPL contracts as a dependency:
+
+```sh
+$ yarn global add truffle@5.0.0-beta.1 # or $ npm install -g truffle@5.0.0-beta.1
+$ truffle init && yarn init # or npm init
+$ yarn add openzeppelin-solidity # or npm install openzeppelin-solidity
+$ yarn add tpl-contracts # or $ npm install tpl-contracts
+```
+
+Then, import it in your contracts like so:
+```solidity
+pragma solidity ^0.4.25;
+
+import "tpl-contracts/contracts/BasicJurisdiction.sol";
+
+
+contract Test is BasicJurisdiction {
+  string public name;
+
+  constructor() public {
+    name = "My First Jurisdiction";
+  }
+}
+```
+
