+# Zirgen Circuit Compiler
+
+Zirgen is a compiler for a domain-specific language, also called "zirgen",
+which creates arithmetic circuits for the RISC Zero proof system.
+
+For the most part, users of RISC Zero should be writing their zkApps in Rust
+and using our RISC-V zkVM rather than building them directly in Zirgen.
+Sometimes, however, it is necessary or desirable to write parts of an
+application as an arithmetic circuit to integrate directly with our proof system
+and achieve better performance. In fact, we have an upcoming version of the zkVM
+circuit written in Zirgen! Zirgen will make it possible to build accelerators
+for important parts of your applications, or even to build entire other VMs that
+integrate into the RISC Zero ecosystem through proof composition. With that said,
+it's still a work in progress and has quite a few rough edges.

+
+* [The recursion circuit](/zirgen/circuit/recursion/)
+* [The RISC-V zkVM](/zirgen/circuit/rv32im/) 
+
+## Circom integration
+
+We also have an integration with Circom in the works -- this will make it
+possible to generate recursion circuit programs that verify witnesses for
+arbitrary Circom circuits. This can be found
+[here](/zirgen/compiler/tools/zirgen-r1cs.cpp).

 ## Introduction
 
 The Zirgen circuit language is a domain-specific language for writing arithmetic
-circuits for the RISC Zero proof system. For the most part, users of RISC Zero
-should be writing their zkApps in Rust and using our RISC-V zkVM rather than
-building them directly in Zirgen. However, sometimes it is necessary or
-desirable to write parts of an application as an arithmetic circuit to integrate
-directly with our proof system and achieve better performance. In fact, our zkVM
-itself is a circuit written in Zirgen! Zirgen makes it possible to build
-accelerators for important parts of your applications, or even to build entire
-other VMs that integrate into the RISC Zero ecosystem through proof composition.
-If that sounds like your goal, read on!
