+# Terraform module for sackd
+
+This is a Terraform module facilitating the deployment of the sackd charm using
+the [Juju Terraform provider](https://github.com/juju/terraform-provider-juju).
+For more information, refer to the
+[documentation](https://registry.terraform.io/providers/juju/juju/latest/docs)
+for the Juju Terraform provider.
+
+## Requirements
+
+This module requires a Juju model to be available. Refer to the [usage](#usage)
+section for more details.
+
+## API
+
+### Inputs
+
+This module offers the following configurable units:
+
+| Name          | Type        | Description                                              | Default      | Required |
+|---------------|-------------|----------------------------------------------------------|--------------|:--------:|
+| `app_name`    | string      | Application name                                         | sackd        |          |
+| `base`        | string      | Base version to use for deployed machine                 | ubuntu@24.04 |          |
+| `channel`     | string      | Channel that charm is deployed from                      | latest/edge  |          |
+| `config`      | map(string) | Map of charm configuration options to pass at deployment | {}           |          |
+| `constraints` | string      | Constraints for the charm deployment                     | "arch=amd64" |          |
+| `model_name`  | string      | Name of the model to deploy the charm to                 |              |    Y     |
+| `revision`    | number      | Revision number of charm to deploy                       | null         |          |
+| `units`       | number      | Number of units to deploy                                | 1            |          |
+
+### Outputs
+
+After applying, the module exports the following outputs:
+
+| Name       | Description                 |
+|------------|-----------------------------|
+| `app_name` | Application name            |
+| `provides` | Map of `provides` endpoints |
+
+## Usage
+
+Users should ensure that Terraform is aware of the Juju model dependency of the
+charm module.
+
+To deploy this module with its required dependency, you can run
+the following command:
+
+```shell
+terraform apply -var="model_name=<MODEL_NAME>" -auto-approve
+```
