## What it is
A curated collection of links and resources for learning type theory and related fields, compiled by Daniel Gratzer. It includes textbooks, papers, and lecture notes aimed at readers without a strong math background.

## Use cases
- learn type theory from scratch
- find textbooks on programming language foundations
- get an introduction to homotopy type theory
- find resources on dependent types
- self-study theoretical computer science
- prepare to read academic PL papers

## When to choose
- you want a curated reading path into type theory
- you have little math background and need accessible starting points
- you want free links to textbooks and lecture notes

## When to avoid
- you need executable software or tooling
- you want a canonical or exhaustive curriculum rather than one person's learning path
- you need up-to-date coverage of the latest research

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: programming-languages, tutorials, awesome-lists
- platform: cross-platform
- tags: type-theory, curated-resources, academic, homotopy-type-theory
