+# Implementing a new emerging platform
+
+This template is a simplified version of the
+[full template](https://github.com/coreos/fedora-coreos-tracker/blob/main/.github/ISSUE_TEMPLATE/implementing-new-platform.md)
+that only includes what is strictly needed to get initial support for a new
+platform in Fedora CoreOS. This simplified version notably does not include the
+steps needed to add new boot images to the release process.
+
+Platforms added via this process are labelled "emerging" and users will have to
+get boot images for them by converting existing images in the right format and
+changing the `ignition.platform.id=<platform>` command line parameter.
+
+This process will be documented using `guestfish` as an example.
+
+## During Development
+
+Create PRs addressing the following:
+
+- [ ] [Ignition](https://github.com/coreos/ignition/) ([example PR](https://github.com/coreos/ignition/pull/918))
+  - [ ] Add userdata fetch
+  - [ ] If the platform supports it (unlikely), add userdata deletion
+- [ ] [Afterburn](https://github.com/coreos/afterburn/) ([example PR](https://github.com/coreos/afterburn/pull/451))
+  - [ ] (Cloud Only) Add relevant attributes
+  - [ ] (Cloud Only) Add SSH key support if available
+  - [ ] (Cloud Only) Add hostname support if available
+  - [ ] (Cloud Only) Add check-in if needed (unlikely)
+- [ ] [fedora-coreos-docs](https://github.com/coreos/fedora-coreos-docs) ([example PR](https://github.com/coreos/fedora-coreos-docs/pull/377))
+  - [ ] Add a `provisioning-<platform>.adoc` that walks through how to setup the new platform
+  - [ ] Add an entry in the `modules/ROOT/nav.adoc` that points to new documentation
+- [ ] (Optional but recommended) Add support for the platform to [kola](https://github.com/coreos/coreos-assembler) to simplify testing
+- Create or ask for a new upstream releases for:
+  - [ ] Ignition
+  - [ ] Afterburn
+- Wait for new images with updated Ignition and Afterburn to reach stable then
+  merge documentation with `guestfish` commands:
+  - [ ] fedora-coreos-docs
+
+## At Release
+
+There are no "At Release" steps as we do not produce new boot images for
+emerging platforms/
