 The `Test.mo` actor imports the (installed) `Map` canister, using `Maps` Candid interface to determine its Motoko type. `Test`'s run method simply puts 24 consecutive entries into Map. These entries are distributed evenly amongst the buckets making up the key-value store. Adding the first entry to a bucket take longer than adding a subsequent one, since the bucket needs to be installed on first use.
 
-This is a Motoko example that does not currently have a Rust variant. 
-
-## Prerequisites
-
-- [x] Install the [IC
-  SDK](https://internetcomputer.org/docs/current/developer-docs/getting-started/install). For local testing, `dfx >= 0.22.0` is required.
-- [x] Clone the example dapp project: `git clone https://github.com/dfinity/examples`
-
-Begin by opening a terminal window.
-
-## Step 1: Setup the project environment
-
-Navigate into the folder containing the project's files and start a local instance of the Internet Computer with the commands:
-
-
-```bash
-cd examples/motoko/classes
-dfx start --background
-```
-
-## Step 2: Deploy the canisters `Map` and `Test`
-
-```bash
-dfx deploy Map --no-wallet
-dfx deploy Test --no-wallet
-```
-
-## Step 3: Invoke the run method of canister `Test`
-
-```bash
-dfx canister call Test run '()'
-```
-
-The output should resemble the following:
-
-```bash
-debug.print: putting: (0, "0")
-debug.print: putting: (1, "1")
-debug.print: putting: (2, "2")
-debug.print: putting: (3, "3")
-debug.print: putting: (4, "4")
-debug.print: putting: (5, "5")
-debug.print: putting: (6, "6")
-debug.print: putting: (7, "7")
-debug.print: putting: (8, "8")
-debug.print: putting: (9, "9")
-debug.print: putting: (10, "10")
-debug.print: putting: (11, "11")
-debug.print: putting: (12, "12")
-debug.print: putting: (13, "13")
-debug.print: putting: (14, "14")
-debug.print: putting: (15, "15")
-debug.print: putting: (16, "16")
-debug.print: putting: (17, "17")
-debug.print: putting: (18, "18")
-debug.print: putting: (19, "19")
-debug.print: putting: (20, "20")
-debug.print: putting: (21, "21")
-debug.print: putting: (22, "22")
-debug.print: putting: (23, "23")
-()

-## Security considerations and best practices
-
-If you base your application on this example, we recommend you familiarize yourself with and adhere to the [security best practices](https://internetcomputer.org/docs/current/references/security/) for developing on the Internet Computer. This example may not implement all the best practices.
+This application's logic is written in [Motoko](https://internetcomputer.org/docs/motoko/home), a programming language designed specifically for developing canisters on ICP.

+## Deploying from ICP Ninja
+
+[![](https://icp.ninja/assets/open.svg)](https://icp.ninja/editor?g=https://github.com/dfinity/examples/tree/master/motoko/classes)
+
+## Build and deploy from the command-line
+
+### 1. [Download and install the IC SDK.](https://internetcomputer.org/docs/building-apps/getting-started/install)
+
+### 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/)
+
+### 3. Navigate into the project's directory.
+
+### 4. Run `dfx start --background --clean && dfx deploy` to deploy the project to your local environment.
