+## Introduction
+
+!> The Stacking implementation is still in development and could change in the coming weeks
+
+In this guide, you'll learn how to use the Stacks CLI to participate in stacking. The CLI is a great way to quickly try out stacking on testnet. To integrate stacking into your application, see the [stacking integration guide](/stacks-blockchain/integrate-stacking).
+
+## Requirements
+
+First, you'll need to understand the [Stacking mechanism](/stacks-blockchain/stacking).
+
+You'll also need [NodeJS](https://nodejs.org/en/download/) `12.10.0` or higher to complete this tutorial. You can verify your installation by opening up your terminal and run the following command:
+
+```bash
+$ node --version
+```
+
+You will also need to install the Stacks CLI from NPM:
+
+```bash
+$ npm install @stacks/cli -g
+```
+
+## Generate A New Key Pair
+
+```bash
+$ stx make_keychain -t
+{
+  "mnemonic": "turn food juice small swing junior trip crouch slot wood nephew own tourist hazard tomato follow trust just project traffic spirit oil diary blue",
+  "keyInfo": {
+    "privateKey": "dca82f838f6e5a893cffc8efe861196252373a5b8b62c0b55ba3a0a7a28795d301",
+    "address": "ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8",
+    "btcAddress": "mqPBWmSGJhrA9x5XJC6qJtFsHnudqZ2XJU",
+    "index": 0
+  }
+}
+```
+
+We'll be using this testnet key pair to perform stacking. But first we'll need to get some testnet tokens.
+
+-> If you're stacking on mainnet, make sure you have an account with sufficient number of Stacks tokens to participate.
+
+## Get Testnet Tokens Using The Faucet
+
+Use the following `curl` command to request tokens from the testnet node's faucet endpoint.
+
+Note that we used the address we generated above as a parameter.
+
+```bash
+curl -X POST https://stacks-node-api.xenon.blockstack.org/extended/v1/faucets/stx?address=ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8
+```
+
+## Check Balance
+
+Confirm that the faucet transaction has completed by checking the balance of your address. The `-t` flag is used to indicate testnet.
+
+```bash
+stx balance ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8 -t
+{
+  "balance": "90000000000000",
+  "locked": "0",
+  "unlock_height": 0,
+  "nonce": 0
+}
+```
+
+## Check Stacking Eligibility
+
+Before we send the stacking transaction, we will need to check if we're eligible for stacking.
+
+This check ensure that we meet the minimum threshold amount of STX required in order to participate in stacking.
+
+The arguments required for the `can_stack` command are:
+
+1. Amount to stack in microstacks, we'll use the entire balance in our account.
+   90000000000000
+
+2. Number of reward cycles to lock up your tokens for stacking, we'll use 10 here.
+   10
+
+3. BTC address to receive stacking rewards. We can use any valid BTC address.
+   mqkccNX5h7Xy1YUku3X2fCFCC54x6HEiHk
+
+4. The address that we will be stacking with. We'll use the address generated previously.
+   ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8
+
+```bash
+stx can_stack 90000000000000 10 mqkccNX5h7Xy1YUku3X2fCFCC54x6HEiHk ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8 -t
+{ eligible: true }
+```
+
+If we meet the conditions to participate in stacking, the command will return true.
+
+## Stacking
+
+Next, we will perform the stacking transaction using the `stack` command.
+
+We need the following 4 arguments:
+
+1. Amount to stack in microstacks.
+   90000000000000
+
+2. Number of reward cycles to lock up your tokens for stacking.
+   10
+
+3. BTC address to receive stacking rewards. This is also referred to as the PoX address.
+   mqkccNX5h7Xy1YUku3X2fCFCC54x6HEiHk
+
+4. The private key to the address we're stacking with, which we generated previously.

+
+```bash
+stx stack 90000000000000 10 mqkccNX5h7Xy1YUku3X2fCFCC54x6HEiHk dca82f838f6e5a893cffc8efe861196252373a5b8b62c0b55ba3a0a7a28795d301
+{
+  txid: '0x2e33ad647a9cedacb718ce247967dc705bc0c878db899fdba5eae2437c6fa1e1',
+  transaction: 'https://testnet-explorer.blockstack.org/txid/0x2e33ad647a9cedacb718ce247967dc705bc0c878db899fdba5eae2437c6fa1e1'
+}
+```
+
+If the commands completes successfully, we'll get back a TXID and a URL to the block explorer showing the transaction status.
+
+Now we should wait until the transaction is confirmed. This usually takes a few minutes.
+
+## Checking Stacking Status
+
+Once the transaction has been confirmed, we can check the stacking status using the `stacking_status` command:
+
+```bash
+stx stacking_status ST1P3HXR80TKT48TKM2VTKCDBS4ET9396W0W2S3K8 -t
+{
+  amount_microstx: '90000000000000',
+  first_reward_cycle: 25,
+  lock_period: 10,
+  unlock_height: 3960,
+  pox_address: {
+    version: '00',
+    hashbytes: '05cf52a44bf3e6829b4f8c221cc675355bf83b7d'
+  }
+}
+```
+
+Here we can see how many microstacks are locked and when they will unlock.
