+# Changes for MinaProtocol
+
+`async_kernel` was forked from `janestreet/async_kernel`. The first changes
+for MinaProtocol were made atop tag v0.12.0 in branch `tracing`.
+
+For OCaml 4.11.2, the Jane Street code at v0.13.0 was merged into the fork.
+Atop that, these changes were made:
+
+ - in `Async_kernel_scheduler`, expose `t`, `long_cycles_with_context`, and
+    `long_jobs_with_context`

+"Async_kernel"
+==============
+
+`Async_kernel` contains `Async`'s core data structures, like `Deferred`.
+`Async_kernel` is portable, and so can be used in JavaScript using Async_js. In
+principle it could also be used on Windows, but no scheduler has been written
+for Async on Windows as of yet.
+
+API documentation for the latest release can be found
+[here][https://ocaml.janestreet.com/ocaml-core/latest/doc/async/index.html].
