Before starting, you already need to have a wallet configured and working. The pool needs to know your wallet address to be able to send payments there. See the [Accepting Monero guide]({{ site.baseurl }}/get-started/accepting) for more information.
Before mining, you should decide if it is worth it or not for you. You have to decide this for yourself, based on your power costs and the hardware that you have available. There are many sites, such as [CryptoCompare](https://www.cryptocompare.com/mining/calculator/xmr)that allow you to enter your miner's speed and power draw, and it will show you the profit (or loss) per week/month.
The XMRig developer provides pre-built binaries for Windows users. They are available on the [GitHub release page](https://github.com/xmrig/xmrig/releases/latest).
Choosing a larger pool means that you will see more frequent (but smaller) payouts, but choosing a smaller pools helps keep the network decentralised. [Miners will not lose any revenue by mining on a smaller pool](https://redd.it/g6uh2l).
Windows users can double click on xmrig.exe. Users of other operating systems should `cd` into the directory that contains XMRig and then type `./xmrig` and press return.
Some anti-viruses flag XMRig as malware because it is often deployed to infected computers to mine without the owner's consent. As it is your computer and you are configuring the miner to mine for you, it is safe to add XMRig to your anti-virus whitelist.
On some CPUs, XMRig tries to increase performance by disabling certain features like your CPU's instruction prefetcher. These operations require root/administrator, so try right clicking xmrig.exe and running it as administrator, or running `sudo ./xmrig` on other systems.
Find the line in config.json that says `algo: null` and change it to `algo: "rx/0"`. By default, XMRig expects the pool to tell it which hashing algorithm to use.
