<p>To get regtest coins, you need to mine them yourself. Bitcoin Core can quickly and easily mine a bunch of blocks, just use the <code>generatetoaddress</code> command. Note that newly mined Bitcoin only become spendable after the coinbase transaction that produces them has 100 confirmations. So if you mine 101 blocks, you will be able to spend the 50 Bitcoin from the first block mined.</p>

<p>For help with the RPCs, there is a <code>help</code> command. You can use that to get a list of available commands. Their names are pretty self explanatory. You can then do <code>help &lt;command&gt;</code> where <code>&lt;command&gt;</code> is some command you need help with. This will give you a more detailed description of the RPC, the parameters it takes, and what the result it returns will look like.</p>

Sorry, I wasn't clear. By regtest I meant I was running it on my own machine only, not connecting to other nodes.

Ah, I missed that. I updated my answer with regtest instructions.

<p>I'm setting up a regtest node on my Windows machine using bitcoin-qt. Here's my config:</p>

<pre><code>regtest=1
txindex=1
server=1
[test]
rpcport=8332
rpcuser=ulu
rpcpassword=***
</code></pre>

<p>Next, I would like to run a transaction using RPC. However, I'm totally lost here:
 1. What is the BTC address I could use for creating a transaction?
 2. How do I "unlock" it to be able to send a transaction?
 3. How do I add some BTC to it to be able to send it and/or pay for the transaction?</p>
