+## Proxy contract verification
+
+Like with the commands above, we have created a set of commands that will help you quickly start verifying proxy contracts. The commands are:
+```bash
+yarn fork:proxy:automatic --network my_tenderly_fork_1
+yarn private:proxy:manual-simple --network sepolia
+```

 When running against a specific network, you must add `--network <NETWORK_NAME>`.

+# Proxy contract verification
+
+This plugin supports verification of proxy contracts, their implementation and all the related contracts.
+In order to successfully verify a proxy contract, please read the chapters about [Verification Modes](#verification-modes) and [Verification Approaches](#verification-approaches) first.
+This will lead you to setup the configuration the right way, so you can verify your proxy contracts and their implementation on Tenderly.
+
+After you have successfully configured `hardhat.config.ts`, you need to populate the configuration in the format that `@nomicfoundation/hardhat-verify` plugin expects, given that this plugin uses their verification beneath for verifying proxies.
+But luckily, we have provided a way to automatically populate the configuration for you, you just need to set the `AUTOMATIC_POPULATE_HARDHAT_VERIFY_CONFIG=true` environment variable.
+
+In order to see how this all plays out, you can clone our [@tenderly/hardhat-tenderly](https://github.com/Tenderly/hardhat-tenderly) repo and navigate to the [examples/contract-verification](https://github.com/Tenderly/hardhat-tenderly/tree/master/examples/contract-verification) directory.
+This directory contains all the possibilities that you can explore in order to verify your proxy contracts.
+Right now we support, both manual and automatic verification of the following proxy contracts:
+- BeaconProxy
+- TransparentUpgradeableProxy
+- UUPSUpgradeableProxy
+
+And we support them on all type of verification modes (e.g. **devnet**, **fork**, **public**, **private**).
