+# Data Source: aws_ssm_patch_baselines
+
+Terraform data source for retrieving AWS SSM (Systems Manager) Patch Baselines.
+
+## Example Usage
+
+### Basic Usage
+
+```terraform
+data "aws_ssm_patch_baselines" "example" {}
+```
+
+### With Filters
+
+```terraform
+data "aws_ssm_patch_baselines" "example" {
+  filter {
+    key    = "OWNER"
+    values = ["AWS"]
+  }
+  filter {
+    key    = "OPERATING_SYSTEM"
+    values = ["WINDOWS"]
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are optional:
+
+* `filter` - (Optional) Key-value pairs used to filter the results. See [`filter`](#filter-argument-reference) below.
+* `default_baselines` - (Optional) Only return baseline identities where `default_baseline` is `true`.
+
+### `filter` Argument Reference
+
+* `key` - (Required) Filter key. See the [AWS SSM documentation](https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_DescribePatchBaselines.html) for valid values.
+* `values` - (Required) Filter values. See the [AWS SSM documentation](https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_DescribePatchBaselines.html) for example values.
+
+## Attribute Reference
+
+This data source exports the following attributes in addition to the arguments above:
+
+* `baseline_identities` - List of baseline identities. See [`baseline_identities`](#baseline_identities-attribute-reference) below.
+
+### `baseline_identities` Attribute Reference
+
+* `baseline_description` - Description of the patch baseline.
+* `baseline_id` - ID of the patch baseline.
+* `baseline_name` - Name of the patch baseline.
+* `default_baseline` - Indicates whether this is the default baseline. AWS Systems Manager supports creating multiple default patch baselines. For example, you can create a default patch baseline for each operating system.
+* `operating_system` - Operating system the patch baseline applies to.
