+## Prerequisites
+
+- Node.js: This script uses the `eosjs` library, which requires Node.js. You can download the latest version of Node.js from the official website (https://nodejs.org/).
+- EOS node: This script interacts with an EOS node through its HTTP API. You will need to have an EOS node running and its HTTP API endpoint URL available.
+
+## Setting up the environment
+
+1. Clone the repository or download the script.
+2. Create a file named `.env` in the same directory as the script.
+3. In the `.env` file, define the following environment variables:
+   - `NODE_URL`: The URL of the HTTP API endpoint of your EOS node.
+   - `PRIVATE_KEY`: The private key of the account that will sign and broadcast the transaction.
+   - `INERY_ACCOUNT`: Your Inery account name.
+   - `TOKEN`: The token you created in your Inery account.
+4. Install the dependencies by running `npm install` in the terminal.
+
+## Running the script
+
+1. Open a terminal and navigate to the directory where the script is located.
+2. Run the script with the following command: `node ./inerynoderpc.mjs` or `npm run MC-RPC`
+
+## Expected output
+
+If the script runs successfully, you should see the signed transaction object and the console output of the `transfer` action of the `inery.token` contract, depending on the script. If an error occurs, the error message will be printed to the console.
