Ollama

I want to install and try Ollama on my own computer.

Official repository: https://github.com/ollama/ollama

Before you do anything:
1. Read the README and install notes in the official repository above, and nothing else. Do not follow third-party tutorials or mirrors.
2. Tell me in plain words what will be installed, what it needs (operating system, memory, graphics card, disk space, accounts) and what it will cost me, if anything.
3. Check my computer against those needs and tell me honestly if it will not work well.

Install it as a regular desktop app: download the latest release for my operating system from the official releases page or the official site, install it, and open it with me.

Rules:
- Show me each command before you run it, and say what it does.
- Ask before anything that deletes files, changes system settings, opens a network port or needs an administrator password.
- Never put my passwords or keys on a command line, or in a file I did not choose.
- When it is installed, help me check it with one small test, and tell me how to start and stop it.
- If something goes wrong, explain it in plain words and do not guess your way around it.

Good to know before you start: This does not replace ChatGPT Plus one for one. Local models are smaller than the frontier models, and quality depends on your hardware. We count it as a replacement for some tasks, not all of them.
