-.Procedure (using a block explorer)
+.Procedure
 
-. Approve the STRK ERC20 contract for the transfer of tokens from your address to the staking contract:
-+
-.. Using a Starknet block explorer, navigate to the STRK contract by searching for xref:tools:important-addresses.adoc#fee_tokens[its address].
+. If you are using a block explorer:
+.. Navigate to the STRK contract by searching for xref:tools:important-addresses.adoc#fee_tokens[its address]
 .. In the contract interface, locate and select the `approve` function.
-.. Enter the following parameters:
-* In *`spender`*, enter the xref:overview.adoc#staking_contract[staking contract's address].
-* In *`amount`*, enter the number of STRK tokens you want to stake (note the xref:overview.adoc#economic_parameters[minimum stake for validators] and that STRK has 18 decimals).
-.. Submit the transaction to execute the approval.
-. Using a Starknet block explorer, navigate to the staking contract by searching for xref:overview.adoc#staking_contract[its address].
-. In the contract interface, locate and select the `stake` function.
-. Enter the following parameters:
-+
-* In *`reward_address`*, enter the address where the rewards will be sent.
-* In *`operational_address`*, enter the address that xref:overview.adoc#first_stage[in the future] will be used for block attestations and sequencing.
-* In *`amount`*, enter the number of STRK tokens you want to stake (note the xref:overview.adoc#economic_parameters[minimum stake for validators] and that STRK has 18 decimals).
-* In *`pool_enabled`*, enter `1` (true) if you wish to enable delegation pooling, otherwise enter `0` (false).
-* In *`commission`*, enter the commission rate for any delegated staking. The rate should be entered as a percentage with precision, where 10000 represents 100%. For example, to set a 5% commission, you would enter 500.
-. Submit the transaction to execute the staking operation.
+. Pre-approve the STRK ERC20 contract for the transfer of tokens from your address to the staking contract by invoking its `approve` function with the following parameters:
+* In the first parameter (`spender`), enter the xref:overview.adoc#staking_contract[staking contract's address].
+* In the second parameter (`amount`), enter the number of STRK tokens you want to stake (note the xref:overview.adoc#economic_parameters[minimum stake for validators] and that STRK has 18 decimals).

+If you using Starkli as CLI tool, the following example, which approves the STRK contract to transfer 1 STRK to the staking contract on Sepolia, can be used as reference:

+* In the first parameter (`reward_address`), enter the address where the rewards will be sent.
+* In the second parameter (`operational_address`), enter the address that xref:overview.adoc#first_stage[in the future] will be used for block attestations and sequencing.
+* In the third parameter (`amount`), enter the number of STRK tokens you want to stake (note the xref:overview.adoc#economic_parameters[minimum stake for validators] and that STRK has 18 decimals).
