-You should add `bin/flux` to your `.gitignore` file, as in the following example:
-
-```gitignore
-# ignore flux binary
-bin/flux

 Note that this action can only be used on GitHub **Linux AMD64** runners.
+The latest stable version of the `flux` binary is downloaded from

+### Air-gapped Environments
+
+To bootstrap Flux on air-gapped environments without access to github.com and ghcr.io, first you'll need 
+to download the `flux` binary, and the container images from a computer with access to internet.
+
+List all container images:
+
+```console
+$ flux install --export | grep ghcr.io
+
+image: ghcr.io/fluxcd/helm-controller:v0.8.0
+image: ghcr.io/fluxcd/kustomize-controller:v0.9.0
+image: ghcr.io/fluxcd/notification-controller:v0.9.0
+image: ghcr.io/fluxcd/source-controller:v0.9.0
+```
+
+Pull the images locally and push them to your container registry:
+
+```sh
+docker pull ghcr.io/fluxcd/source-controller:v0.9.0
+docker tag ghcr.io/fluxcd/source-controller:v0.9.0 registry.internal/fluxcd/source-controller:v0.9.0
+docker push registry.internal/fluxcd/source-controller:v0.9.0
+```
+
+Copy `flux` binary to a computer with access to your air-gapped cluster,
+and create the pull secret in the `flux-system` namespace:
+
+```sh
+kubectl create ns flux-system
+
+kubectl -n flux-system create secret generic regcred \
+    --from-file=.dockerconfigjson=/.docker/config.json \
+    --type=kubernetes.io/dockerconfigjson
+```
+
+Finally, bootstrap Flux using the images from your private registry:
+
+```sh
+flux bootstrap <GIT-PROVIDER> \
+  --registry=registry.internal/fluxcd \
+  --image-pull-secret=regcred \
+  --hostname=my-git-server.internal
+```
+
+Note that when running `flux bootstrap` without specifying a `--version`,
+the CLI will use the manifests embedded in its binary instead of downloading
+them from GitHub. You can determine which version you'll be installing,
+with `flux --version`.

 # Roadmap
 
-In our planning discussions we identified broad three areas of work:
+!!! hint "Production readiness"
+    The Flux custom resource definitions which are at `v1beta1` and `v2beta1`
+    and their controllers are considered stable and production ready.
+    Going forward, breaking changes to the beta CRDs will be accompanied by a conversion mechanism.
+
+The following components (included by default in [flux bootstrap](../guides/installation.md#bootstrap))
+are considered production ready:
+
+- [source-controller](../components/source)
+- [kustomize-controller](../components/kustomize)
+- [notification-controller](../components/notification)
+- [helm-controller](../components/helm)
+
+The following GitOps Toolkit APIs are considered production ready:
+
+- `source.toolkit.fluxcd.io/v1beta1`
+- `kustomize.toolkit.fluxcd.io/v1beta1`
+- `notification.toolkit.fluxcd.io/v1beta1`
+- `helm.toolkit.fluxcd.io/v2beta1`
+
+## The road to Flux v2 GA
+
+In our planning discussions we have identified these possible areas of work,
+this list is subject to change while we gather feedback:
+
+- Stabilize the image automation APIs
+    * Review the spec of `ImageRepository`, `ImagePolicy` and `ImageUpdateAutomation`
+    * Promote the image automation APIs to `v1beta1`
+    * Include the image automation controllers in the default components list
+
+- Improve the documentation
+    * Gather feedback on the [migration guides](https://github.com/fluxcd/flux2/discussions/413) and address more use-cases
+    * Incident management and troubleshooting guides
+    * Cloud specific guides (AWS, Azure, Google Cloud, more?)
+    * Consolidate the docs under [fluxcd.io](https://fluxcd.io) website
+    
+## The road to Flux v1 feature parity
+
+In our planning discussions we identified three areas of work:
 
 - Feature parity with Flux v1 in read-only mode
 - Feature parity with the image-update functionality in Flux v1
 - Feature parity with Helm Operator v1
 
-All of the above will constitute "Flux v2".
