+# Configuration migrations
+
+This document describes breaking changes in the configuration file format between Constellation releases.
+
+## Migrating from CLI versions before 2.3
+
+- The `sshUsers` field was deprecated in v2.2 and has been removed from the configuration in v2.3.
+  As an alternative for SSH, check the workflow section [Connect to nodes](../workflows/troubleshooting.md#connect-to-nodes).
+- The `image` field for each cloud service provider has been replaced with a global `image` field. Use the following mapping to migrate your configuration:
+    <details>
+    <summary>Show all</summary>
+
+    | CSP   | old image                                                                                                                                                                             | new image |

+- The `enforcedMeasurements` field has been removed and merged with the `measurements` field.
+  - To migrate your config containing a new image (`v2.3` or greater), remove the old `measurements` and `enforcedMeasurements` entries from your config and run `constellation fetch-measurements`
+  - To migrate your config containing an image older than `v2.3`, remove the `enforcedMeasurements` entry and replace the entries in `measurements` as shown in the example below:
+

+# Supply chain levels for software artifacts (SLSA) adoption
+
+[Supply chain Levels for Software Artifacts, or SLSA (salsa)](https://slsa.dev/) is a framework for improving and grading a project's build system and engineering processes. SLSA focuses on security improvements for source code storage as well as build system definition, execution, and observation. SLSA is structured in [four levels](https://slsa.dev/spec/v0.1/levels). This page describes the adoption of SLSA for Constellation.
+
+:::info
+SLSA is still in alpha status. The presented levels and their requirements might change in the future. We will adopt any changes into our engineering processes, as they get defined.
+:::
+
+## Level 1 - Adopted
+
+**[Build - Scripted](https://slsa.dev/spec/v0.1/requirements#scripted-build)**
+
+All build steps are automated via [CMake](https://github.com/edgelesssys/constellation/blob/main/CMakeLists.txt) and [GitHub Actions](https://github.com/edgelesssys/constellation/tree/main/.github).
+
+**[Provenance - Available](https://slsa.dev/spec/v0.1/requirements#available)**
+
+Provenance for the CLI is generated using the [slsa-github-generator](https://github.com/slsa-framework/slsa-github-generator).
+
+## Level 2 - Adopted
+
+**[Source - Version Controlled](https://slsa.dev/spec/v0.1/requirements#version-controlled)**
+
+Constellation is hosted on GitHub using git.
+
+**[Build - Build Service](https://slsa.dev/spec/v0.1/requirements#build-service)**
+
+All builds are carried out by [GitHub Actions](https://github.com/edgelesssys/constellation/tree/main/.github).
+
+**[Provenance - Authenticated](https://slsa.dev/spec/v0.1/requirements#authenticated)**
+
+Provenance for the CLI is signed using the [slsa-github-generator](https://github.com/slsa-framework/slsa-github-generator). Learn [how to verify the CLI](../workflows/verify-cli.md) using the signed provenance, before using it for the first time.
+
+**[Provenance - Service Generated](https://slsa.dev/spec/v0.1/requirements#service-generated)**
+
+Provenance for the CLI is generated using the [slsa-github-generator](https://github.com/slsa-framework/slsa-github-generator) in GitHub Actions.
+
+## Level 3 - Adopted
+
+**[Source - Verified History](https://slsa.dev/spec/v0.1/requirements#verified-history)**
+
+The [Edgeless Systems](https://github.com/edgelesssys) GitHub organization [requires two-factor authentication](https://docs.github.com/en/organizations/keeping-your-organization-secure/managing-two-factor-authentication-for-your-organization/requiring-two-factor-authentication-in-your-organization) for all members.
+
+**[Source - Retained Indefinitely](https://slsa.dev/spec/v0.1/requirements#retained-indefinitely)**
+
+Since we use GitHub to host the repository, an external person can't modify or delete the history. Before a pull request can be merged, an explicit approval from an [Edgeless Systems](https://github.com/edgelesssys) team member is required.
+
+The same holds true for changes proposed by team members. Each change to `main` needs to be proposed via a pull request and requires at least one approval.
+
+The [Edgeless Systems](https://github.com/edgelesssys) GitHub organization admins control these settings and are able to make changes to the repository's history should legal requirements necessitate it. These changes require two-party approval following the obliterate policy.
+
+**[Build - Build as Code](https://slsa.dev/spec/v0.1/requirements#build-as-code)**
+
+All build files for Constellation are stored in [the same repository](https://github.com/edgelesssys/constellation/tree/main/.github).
+
+**[Build - Ephemeral Environment](https://slsa.dev/spec/v0.1/requirements#ephemeral-environment)**
+
+All GitHub Action workflows are executed on [GitHub-hosted runners](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners). These runners are only available during workflow.
+
+We currently don't use [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners).
+
+**[Build - Isolated](https://slsa.dev/spec/v0.1/requirements#isolated)**
+
+As outlined in the previous section, we use GitHub-hosted runners, which provide a new, isolated and ephemeral environment for each build.
+
+Additionally, the [SLSA GitHub generator](https://github.com/slsa-framework/slsa-github-generator#generation-of-provenance) itself is run in an isolated workflow with the artifact hash as defined inputs.
+
+**[Provenance - Non-falsifiable](https://slsa.dev/spec/v0.1/requirements#non-falsifiable)**
+
+As outlined by [SLSA GitHub generator](https://github.com/slsa-framework/slsa-github-generator) it already fulfills the non-falsifiable requirements for SLSA Level 3. The generated provenance is signed using [sigstore](https://sigstore.dev/) with an OIDC based proof of identity.
+
+## Level 4 - In Progress
+
+We strive to adopt certain aspect of SLSA Level 4 that support our engineering process. At the same time, SLSA is still in alpha status and the biggest changes to SLSA are expected to be around Level 4.

+# Terraform usage
+
+[Terraform](https://www.terraform.io/) is an Infrastructure as Code (IaC) framework to manage cloud resources. This page explains how Constellation uses it internally and how advanced users may manually use it to have more control over the resource creation.
+
+:::info
+Information on this page is intended for users who are familiar with Terraform.
+It's not required for common usage of Constellation.
+See the [Terraform documentation](https://developer.hashicorp.com/terraform/docs) if you want to learn more about it.
+:::
+
+## Terraform state files
+
+Constellation keeps Terraform state files in subdirectories of the workspace together with the corresponding Terraform configuration files and metadata.
+The subdirectories are created on the first Constellation CLI action that uses Terraform internally.
+
+Currently, these subdirectories are:
+
+* `constellation-terraform` - Terraform state files for the resources of the Constellation cluster
+* `constellation-iam-terraform` - Terraform state files for IAM configuration
+
+As with all commands, commands that work with these files (e.g., `create`, `terminate`, `iam`) have to be executed from the root of the cluster's [workspace directory](../architecture/orchestration.md#workspaces). You usually don't need and shouldn't manipulate or delete the subdirectories manually.
+
+## Interacting with Terraform manually
+
+Manual interaction with Terraform state created by Constellation (i.e., via the Terraform CLI) should only be performed by experienced users. It may lead to unrecoverable loss of cloud resources. For the majority of users and use cases, the interaction done by the [Constellation CLI](cli.md) is sufficient.
