# Adding Instructions

After creating a transaction it will be in the "Draft" status which allows the creator of the Transaction to attach one or multiple instructions. 

Similarly to creating a transaction, each instruction attached to a transaction will have its corresponding data saved in an account represented by an[ instruction PDA](/squads-v3-docs/development/pdas/instruction.md).

Attaching an instruction will automatically bump up the instructionIndex, so when attaching an instruction ensure that the supplied instruction PDA is derived correctly (instructionIndex + 1).

Here is an example of creating a transaction and attaching an instruction, which will withdraw 1 SOL from the vault (authority) to a destination address:

```
// fetch the multsig account to get the TX index
const multisigAccount = await squadsProgram.account.fetch(multisig);

// bump up the transactionIndex by 1 to seed the new tx address
const transactionIndex = new anchor.BN(multsigAccount.transactionIndex + 1);
// find the tx address/pda for the to-be-created transaction
const [transaction] = await anchor.web3.PublicKey.findProgramAddress([
    anchor.utils.bytes.utf8.encode("squad"),
    multisig.toBuffer(),
    transactionIndex.toBuffer("le", 4),
    anchor.utils.bytes.utf8.encode("transaction")
], squadsProgram.programId);

// create the transaction account with the authorityIndex of 1
const createIx = await program.methods.createTransaction(1)
    .accounts({
        multisig,
        transaction,
        creator: wallet.publicKey
    })
    .rpc();

// use instructionIndex = 1, since this is the first and only ix
const instructionIndex = new anchor.BN(1);
// get the instruction address / PDA
const [instruction] = await anchor.web3.PublicKey.findProgramAddress([
    anchor.utils.bytes.utf8.encode("squad"),
    transaction.toBuffer(),
    instructionIndex.toBuffer("le", 1),
    anchor.utils.bytes.utf8.encode("instruction")
], squadsProgram.programId);

// find the authority for the authorityIndex = 1
const authorityIndex = anchor.BN(1);
const [authority] = await anchor.web3.PublicKey.findProgramAddress([
    anchor.utils.bytes.utf8.encode("squad"),
    multisig.toBuffer(),
    authorityIndex.toBuffer("le", 4),  // note authority index is an u32 (4 byte)
    anchor.utils.bytes.utf8.encode("authority")
], squadsProgram.programId);

// define the instruction to withdraw funds from the authority/vault
// and supply the authority
const withdrawIx = anchor.web3.SystemProgram.transfer({
    fromPubkey: authority,
    lamports: anchor.web3.LAMPORTS_PER_SOL,
    toPubkey: destination // public key of where to send the SOL
});

// add the instruction to the transaction, using the withdrawIx as a parameter
await program.methods.addInstruction(withdrawIx)
    .accounts({
        multisig,
        transaction,
        instruction,
        creator: wallet.publicKey
    })
    .rpc();

```

We now have a new transaction, with a single instruction attached to it.
