+# zkSync Era upgradable example
+
+This project demonstrates how to compile and deploy upgadable smart contracts in zkSync Era using the Hardhat plugins.
+
+## Prerequisites
+
+- node.js 14.x or later.
+- yarn.
+
+## Configuration
+
+Plugin configuration is located in [`hardhat.config.ts`](./hardhat.config.ts).
+You should only change the zkSync network configuration.
+
+`hardhat.config.ts` example with zkSync network configured with the name `zkTestnet` and `sepolia` used as the underlying layer 1 network:
+```ts
+import '@matterlabs/hardhat-zksync-solc';
+import '@matterlabs/hardhat-zksync-deploy';
+import '@matterlabs/hardhat-zksync-upgradable';
+
+import { HardhatUserConfig } from 'hardhat/types';
+
+const config: HardhatUserConfig = {
+    networks: {
+        sepolia: {
+            url: 'https://rpc.ankr.com/eth_sepolia' // you can use either the URL of the Ethereum Web3 RPC, or the identifier of the network (e.g. `mainnet` or `rinkeby`)
+        },
+        zkTestnet: {
+            url: 'https://sepolia.era.zksync.dev', // you should use the URL of the zkSync network RPC
+            ethNetwork: 'sepolia',
+            zksync: true
+        },
+    }
+};
+
+export default config;
+```
+
+If you don't specify zkSync network (`--network`), `local-setup` with <http://localhost:8545> (Ethereum RPC URL) and <http://localhost:3050> (zkSync RPC URL) will be used.
+
+## Usage
+
+Before using plugins, you need to build them first
+
+```sh
+# Run the following in the *root* of the repo.
+yarn
+yarn build
+```
+
+After that you should be able to run plugins:
+
+```sh
+# Run the following in `examples/upgradable-example` folder.
+yarn
+yarn hardhat compile
+```
+
+- `yarn hardhat compile`: compiles all the contracts in the `contracts` folder.
+
+To run a specific end-to-end script in the `scripts` folder, use the following command
+
+```
+yarn hardhad run ./scipts/<SCRIPT_NAME>
+```
+
+- Example: `yarn hardhat run ./scripts/deploy-box-proxy.ts`
