# Nock - [What is Nock?](https://docs.urbit.org/nock/what-is-nock.md): Introduction to Nock, Urbit's minimal assembly language and computation standard that underlies all of Urbit OS and Hoon compilation. - [Decrement](https://docs.urbit.org/nock/decrement.md): Exercise in implementing decrement in Nock as a practice for understanding the language. - [Definition](https://docs.urbit.org/nock/definition.md): Formal definition of Nock with reduction rules and combinator specifications. - [Fast Hints and Jets](https://docs.urbit.org/nock/jetting.md): Runtime jetting system that accelerates Nock computation through fast hints. Cold state, hot state, warm state. - [Implementations](https://docs.urbit.org/nock/implementations.md): Collection of Nock interpreter implementations in various programming languages. - [Specification](https://docs.urbit.org/nock/specification.md): Complete Nock specification explaining the data model, reductions, and operational semantics. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
