+### Acceptance tests
+
+The project has a limited set of acceptance tests which are run against a real Proxmox
+instance. These tests are developed alongside the framework-based resource and datasource implementations, and are located in the `fwprovider/tests` directory.
+
+To run the acceptance tests, you need to have a Proxmox instance available. See more details in the [Setup Proxmox for Tests](./howtos/setup-proxmox-for-tests/README.md) section.
+Create a `testacc.env` file in the project's root directory with the following contents:
+
+```env
+TF_ACC=1
+PROXMOX_VE_API_TOKEN="root@pam!<token name>=<token value>"
+PROXMOX_VE_ENDPOINT="https://<pve instance>:8006/"
+PROXMOX_VE_SSH_AGENT="true"
+PROXMOX_VE_SSH_USERNAME="root"
+```
+
+Then use `make testacc` to run the acceptance tests.
+
+> [!NOTE]
+> The acceptance tests support is still in development. Only handful of resources and data sources are covered by the tests. Some tests may require extra configuration on the Proxmox instance, and fail if the configuration is not present.
