Lean mathlib
Mathlib is a user maintained library for the Lean theorem prover. It contains both programming infrastructure and mathematics, as well as tactics that use the former and allow to develop the latter.
Installation
You can find detailed instructions to install Lean, mathlib, and supporting tools on our website.

Documentation
Besides the installation guides above and Lean's general documentation, the documentation of mathlib consists of:
- The mathlib docs: documentation generated
automatically from the source
.leanfiles. In addition to the pages generated for each file in the library, the docs also include pages on:- tactics,
- commands,
- hole commands, and
- attributes.
- A description of currently covered theories, as well as an overview for mathematicians.
- A couple of tutorial Lean files
- Some extra Lean documentation not specific to mathlib (see "Miscellaneous topics")
- Documentation for people who would like to contribute to mathlib
