 Now you have your wallet set up. Let's proceed with getting some
 tokens from the faucet. The testnet has a running faucet which is
-able to airdrop arbitrary tokens. For example purposes, we'll use
-the tokens called `DARKfZX1utGbz8ZpnvtCH6i46nSDZEEGa5fMnhoubWPq` and
-`BobvfQrDaf32VNhVtX6Adyi3WGfPpPYZPJBn6rnrxHKm`
+able to airdrop native network tokens. 
 
 So let's airdrop some of these into our wallet:
 
 ```
-$ ./drk airdrop 42.69 DARKfZX1utGbz8ZpnvtCH6i46nSDZEEGa5fMnhoubWPq
-$ ./drk airdrop 13.37 BobvfQrDaf32VNhVtX6Adyi3WGfPpPYZPJBn6rnrxHKm
+$ ./drk airdrop 42.69
 ```
 
 There is a limit of 100 for testnet airdrops currently.

+# Minting tokens
+
+On the DarkFi network, we're also able to mint custom tokens with
+some supply. To do this, we need to generate a mint authority keypair,
+and derive a token ID from it. We can simply do this by executing the
+following command:
+
+```
+$ ./drk token generate-mint
+```
+
+This will generate a new token mint authority and will tell you what
+your new token ID is. For tutorial purposes, let's assume the tokens
+we will be minting are `DARKfZX1utGbz8ZpnvtCH6i46nSDZEEGa5fMnhoubWPq`
+and `AcABG4fnmBuT5vuXV8TLdEV8panhk5SdtBZxCCLqQxyL`.
+
+You can also list your mint authorities with:
+
+```
+$ ./drk token list
+```
+
+Now let's mint some tokens to ourself. First grab your wallet address,
+and then create the token mint transaction, and finally - broadcast it:
+
+```
+$ ./drk wallet --address
+$ ./drk token mint DARKfZX1utGbz8ZpnvtCH6i46nSDZEEGa5fMnhoubWPq 42.69 YOUR_ADDRESS > mint_tx
+$ ./drk broadcast < mint_tx
+
+$ ./drk token mint AcABG4fnmBuT5vuXV8TLdEV8panhk5SdtBZxCCLqQxyL 20.0 YOUR_ADDRESS > mint_tx
+$ ./drk broadcast < mint_tx
+```
+
+Now the transaction should be published to the network. If you have
+an active block subscription (which you can do with `drk subscribe`),
+then when the transaction is finalized, your wallet should have your
+new tokens listed when you request to see the balance.
