+## Build and deploy from the command-line
+
+### 1. [Download and install the IC SDK.](https://internetcomputer.org/docs/building-apps/getting-started/install)
 
-The `/backend` folder contains the Rust smart contract:
+### 2. Download your project from ICP Ninja using the 'Download files' button on the upper left corner, or [clone the GitHub examples repository.](https://github.com/dfinity/examples/)
 
-- `Cargo.toml`, which defines the crate that will form the backend
-- `lib.rs`, which contains the actual smart contract, and exports its interface
+### 3. Navigate into the project's directory.
 
-## Build and deploy from the command-line
+### 4. Run `dfx start --background --clean && dfx deploy` to deploy the project to your local environment. 
 
-To migrate your ICP Ninja project off of the web browser and develop it locally, follow these steps. These steps are necessary if you want to deploy this project for long-term, production use on the mainnet.
+## Security considerations and best practices
 
-### 1. Download your project from ICP Ninja using the 'Download files' button on the upper left corner under the pink ninja star icon.
+If you base your application on this example, it is recommended that you familiarize yourself with and adhere to the [security best practices](https://internetcomputer.org/docs/building-apps/security/overview) for developing on ICP. This example may not implement all the best practices.
 
-### 2. Open the `BUILD.md` file for further instructions.
