+  short_description: "CHERI-enabled fork of the seL4 microkernel"
+  description: "seL4 is a Microkernel that aims to improve speed and reliability, whilst having guaranteed behaviour with formal mathematical proofs. The CHERI fork of this adds RISC-V and Morello CHERI support to seL4. It utilizes the seL4 Microkit (a collection of abstractions for basic features) to provide a functional environment."
+  status: |-
+    Active development takes place in the [CHERI-Alliance repository](https://github.com/CHERI-Alliance/CHERI-seL4) on the `cheri-microkit` branch. The CHERI-aware seL4 microkernel (CHERI-seL4) is currently not formally verified, and is experimental.
+
+    Technical discussion and design proposals for integrating CHERI into seL4: [RFC-15: Support CHERI/Morello in seL4](https://github.com/seL4/rfcs/pull/21).

+    The active repository is [CHERI-Alliance/CHERI-seL4](https://github.com/CHERI-Alliance/CHERI-seL4) and [CHERI-Alliance/CHERI-Microkit](https://github.com/CHERI-Alliance/CHERI-Microkit).
+    
+    Builds are managed via the [cheribuild](https://github.com/CTSRD-CHERI/cheribuild) tool. Dependencies include a specific CHERI-forked QEMU, LLVM, and GDB, as well as Rust for the Microkit.
+  slack: |-
+    Support is generally discussed in the [CHERI CPU Slack](https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/cheri-slack.html) in the `#seL4` channel.

+  meetings: |-
+    The CHERI Alliance seL4 working group hold meetings on the last Thursday of every month.
