+### Migrating from `v0` to `v1`
+
+`v1` use [atmos](https://atmos.tools/cli/commands/docs/generate) instead of [build-harness](https://github.com/cloudposse/build-harness).
+You can drop `Makefile` if you use it only for readme generation.
+To support atmos reaadme generation, you must create `atmos.yaml` config. 
+The configuration depends on your repo - please follow this [documentation](https://atmos.tools/cli/commands/docs/generate)
+
+Example: 
+
+```yaml filename="atmos.yaml"
+docs:
+generate:
+  readme:
+    base-dir: .
+    input:
+      - "./README.yaml"
+    template: "https://.../README.md.gotmpl"
+    output: "./README.md"
+    terraform:
+      source: src/
+      enabled: false
+      format: "markdown"
+      show_providers: false
+      show_inputs: true
+      show_outputs: true
+      sort_by: "name"
