## Installing VS Code



VS Code is the recommended IDE for working with Lean 4. To install VS Code, follow these steps:



1. Visit the official VS Code [website](https://code.visualstudio.com).

2. Download the latest version of VS Code for your operating system (Windows, macOS, or Linux).

3. Follow the installation instructions provided on the website to complete the setup process.



Once the installation is complete, you can proceed with configuring VS Code for Lean 4 development.



## Installing Lean 4

## Search Engines



- [Lean Package Registry](https://reservoir.lean-lang.org)

- [Mathlib documentation](https://leanprover-community.github.io/mathlib4_docs/) is a great reference,

   but you either need to know where to look, or what things are named.

   To help with naming, you can reference the [naming conventions](https://leanprover-community.github.io/mathlib_docs/naming.html).

- [Loogle](https://loogle.lean-lang.org) is useful if you know something about the types appearing

  in the statement.

- [Moogle](https://moogle.ai) is useful if you only know the natural language phrasing.

- [LeanSearch](https://leansearch.net)

- [Zulip Channel "Is There Code for X?"](https://leanprover.zulipchat.com/#narrow/stream/217875-Is-there-code-for-X.3F)
