   ### Config
 
-  The action expects the atmos gitops configuration file to be present in the repository in `./.github/config/atmos-gitops.yaml`.
+  The action expects the atmos configuration file `atmos.yaml` to be present in the repository.
   The config should have the following structure:

+  ### Migrating from `v1` to `v2`
+  
+  The notable changes in `v2` are:
+  
+  - `v2` works only with `atmos >= 1.63.0`
+  - `v2` drops `install-terraform` input because terraform is not required for affected stacks call
+  - `v2` drops `atmos-gitops-config-path` input and the `./.github/config/atmos-gitops.yaml` config file. Now you have to use GitHub Actions environment variables to specify the location of the `atmos.yaml`.
+  
+  The following configuration fields now moved to GitHub action inputs with the same names
+  
+  |         name            |
+  |-------------------------|
+  | `atmos-version`         |
+  | `atmos-config-path`     |
+  
+  
+  The following configuration fields moved to the `atmos.yaml` configuration file.
+  
+  |              name        |    YAML path in `atmos.yaml`                    |
+  |--------------------------|-------------------------------------------------|
+  | `aws-region`             | `integrations.github.gitops.artifact-storage.region`     | 
+  | `terraform-state-bucket` | `integrations.github.gitops.artifact-storage.bucket`     |
+  | `terraform-state-table`  | `integrations.github.gitops.artifact-storage.table`      |
+  | `terraform-state-role`   | `integrations.github.gitops.artifact-storage.role`       |
+  | `terraform-plan-role`    | `integrations.github.gitops.role.plan`          |
+  | `terraform-apply-role`   | `integrations.github.gitops.role.apply`         |
+  | `terraform-version`      | `integrations.github.gitops.terraform-version`  |
+  | `enable-infracost`       |  `integrations.github.gitops.infracost-enabled` |
+  | `sort-by`                |  `integrations.github.gitops.matrix.sort-by`    |
+  | `group-by`               |  `integrations.github.gitops.matrix.group-by`   |
+  
+  
+  For example, to migrate from `v1` to `v2`, you should have something similar to the following in your `atmos.yaml`:
+  
+  `./.github/config/atmos.yaml`
+  ```yaml
+  # ... your existing configuration
+  
+  integrations:
+    github:
+      gitops:
+        terraform-version: 1.5.2
+        infracost-enabled: false
+        artifact-storage:
+          region: us-east-2
+          bucket: cptest-core-ue2-auto-gitops
+          table: cptest-core-ue2-auto-gitops-plan-storage
+          role: arn:aws:iam::xxxxxxxxxxxx:role/cptest-core-ue2-auto-gitops-gha
+        role:
+          plan: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
+          apply: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
+        matrix:
+          sort-by: .stack_slug
+          group-by: .stack_slug | split("-") | [.[0], .[2]] | join("-")
+  ```
+  
+  `.github/workflows/main.yaml`
+  ```yaml
+  - name: Selected Components
+    id: components
+    uses: cloudposse/github-action-atmos-terraform-select-components@v2
+    with:
+      atmos-config-path: ./rootfs/usr/local/etc/atmos/
+      jq-query: 'to_entries[] | .key as $parent | .value.components.terraform | to_entries[] | select(.value.settings.github.actions_enabled // false) | [$parent, .key] | join(",")'
+  ``` 
+  
+  This corresponds to the `v1` configuration (deprecated) below.
+  
+  The `v1` configuration file `./.github/config/atmos-gitops.yaml` looked like this:
+  ```yaml
+  atmos-version: 1.45.3
+  atmos-config-path: ./rootfs/usr/local/etc/atmos/
+  terraform-state-bucket: cptest-core-ue2-auto-gitops
+  terraform-state-table: cptest-core-ue2-auto-gitops
+  terraform-state-role: arn:aws:iam::xxxxxxxxxxxx:role/cptest-core-ue2-auto-gitops-gha
+  terraform-plan-role: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
+  terraform-apply-role: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
+  terraform-version: 1.5.2
+  aws-region: us-east-2
+  enable-infracost: false
+  sort-by: .stack_slug
+  group-by: .stack_slug | split("-") | [.[0], .[2]] | join("-")  
+  ```
+  
+  And the `v1` GitHub Action Workflow looked like this.
+  
+  `.github/workflows/main.yaml`
+  ```yaml
+  - name: Selected Components
+    id: components
+    uses: cloudposse/github-action-atmos-terraform-select-components@v1
+    with:
+      atmos-gitops-config-path: ./.github/config/atmos-gitops.yaml
+      jq-query: 'to_entries[] | .key as $parent | .value.components.terraform | to_entries[] | select(.value.settings.github.actions_enabled // false) | [$parent, .key] | join(",")'
+  
+  ```
+
+
   ### Migrating from `v0` to `v1`
   
   1. `v1` replaces the `jq-query` input parameter with a new parameter called `selected-filter` to simplify the query for end-users.
