-## Circuit Constraint Extraction
+### Circuit Generation Process
+
+Since these constraint capabilities are missing, the Mina rust nodes require
+externally generated circuit data. The following process describes how circuits
+are created and distributed using the original Mina codebase:
+
+:::warning Work in Progress
+
+This should be updated when a release of the OCaml node happens that contains code to
+export circuits, and when command to export circuits is added, and CI is updated
+to check for latest circuits
+
+:::
+
+1. Build mina <b>OCaml</b> node from source with commit after
+   [`6961849`](https://github.com/MinaProtocol/mina/commit/6961849f17d564c39e7d45e01e3ddda9a09602a4)
+
+2. Running the circuit generation process using the branch above
+   - Launch the OCaml node which produces circuit cache data in
+     `/tmp/coda_cache_dir`
+   - The branch dumps the usual circuit data plus extra data specifically
+     required by the Mina rust nodes, see
+     [Circuit somponents](#circuit-components)
+   - The process also dumps blocks for use in tests, see
+     [Testing strategy](#testing-strategy)
+   - Integration with mainline Mina would streamline future circuit generation
+
+3. The generated circuit blobs are then:
+   - Committed to the dedicated repository:
+     https://github.com/o1-labs/circuit-blobs
+   - Released as GitHub releases for versioning and distribution
+
+### Circuit Components
+
+Each circuit consists of multiple components that are loaded and cached
+independently:
