Install Git
Install Git on macOS, Linux, and Windows, set your name and email so commits get attributed to you, and confirm it all worked in one command.
Install Node.js and npm without future regret
Install Node and npm through a version manager so you can switch versions per project. fnm is my pick, with nvm and Volta as alternatives.

Leave system Python alone. Install uv, then let it handle Python versions and per-project virtual envs from one fast binary.
Install Docker
Get Docker running on macOS, Linux, or Windows, confirm it with hello-world, and dodge the licensing and resource traps that trip people up.
Install Ollama
Get Ollama running on macOS, Linux, or Windows, pull your first model, and confirm it works with ollama list. The shortest path to a local LLM.
Install llama.cpp
Build llama.cpp from source with Metal or CUDA, then run a GGUF model with llama-cli. The closest thing to bare-metal local inference.
Install LM Studio
Install LM Studio on macOS, Linux, and Windows, then flip on the local OpenAI-compatible server so any client library can talk to a model on your own machine.
