+# Setting a gas price threshold on Chainlink Automation upkeeps
+
+This project provides a script you can use to configure and set a maximum gas price for your Automation upkeep.
+
+## Installation
+
+To set up the project, follow these steps:
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/smartcontractkit/automation-gas-threshold
+   ```
+1. Navigate to the directory for this script:
+   ```bash
+   cd automation-gas-threshold
+   ```
+1. Install the required dependencies:
+
+   ```bash
+   npm install
+   ```
+
+## Usage
+
+1.  Set the following variables:
+
+    - YOUR_RPC_URL: The RPC URL for your provider (such as Alchemy or Infura)
+    - YOUR_PRIVATE_KEY: Your wallet's private key
+    - YOUR_UPKEEP_ID: The ID of the Automation upkeep you want to configure.
+
+1.  Within the `offchainConfig` variable, set your `maxGasPrice` in wei. Do not use
+    quotation marks around the value you set for `maxGasPrice`. If this string
+    is formatted incorrectly, the feature does not work.
+
+    `{"maxGasPrice":2000000000}`
+
+1. Run the script:
+    ```bash
+    node index.js
+    ```
