First, what is Bitcoin Core? It’s basically the backbone of the entire Bitcoin network it keeps track of all transactions that have ever happened and makes sure they are valid. Now Inscriptions. These are essentially digital signatures that can be added to a transaction on top of regular bitcoin data. They allow for more complex smart contracts, which is pretty cool!

So how do we install Bitcoin Core? Well, first you need to download the software from their website (https://bitcoin.org/en/bitcoin-core/) and then follow these simple steps:

1. Extract the files somewhere on your computer (like a folder called “BitcoinCore”)

2. Open up a terminal or command prompt in that directory

3. Run the following commands:

`./bitcoind` to start the Bitcoin Core daemon (this is like the engine of the software)
4. Wait for it to sync with the network (this can take several hours depending on your internet speed and how many transactions have been made since you last synced)

5. Once it’s done syncing, open up another terminal or command prompt in that same directory

6. Run `./bitcoin-cli` to access the Bitcoin Core CLI (command line interface)

7. Type `getinfo` and hit enter to see some basic information about your node (like version number, block height, etc.)

8. To create a new transaction with an Inscription, you’ll need to use the `createrawtransaction` command followed by various other commands depending on what you want to do. Here’s an example:

`./bitcoin-cli createrawtransaction ‘[“03d98e7140bfc25a6b42fe8d0b2ae93ce9fcce8f3f9a5da4f20ebfd8ddac49301:1.0”]’ ‘{“inscription”: “Hello, world!”, “expiration_height”: 100}’`
This creates a new transaction with an Inscription that says “Hello, world!” and sets the expiration height to 100 (meaning it will be valid for up to 100 more blocks before being rejected)

9. Once you’ve created your transaction, use `decoderawtransaction` to make sure everything is correct:

`./bitcoin-cli decoderawtransaction ` (replace “” with the output of the previous command)
10. If it looks good, broadcast your transaction using `sendrawtransaction`:
`./bitcoin-cli sendrawtransaction ` (again, replace “” with the output of the previous command)

And that’s it! You should now have a transaction on the Bitcoin network with an Inscription attached to it.
