+## Manual Testing
+
+You can manually test the provider by running it locally. This is useful for
+testing changes to the provider before submitting a PR.
+
+- Create a $HOME/.terraformrc (POSIX) or %APPDATA%/terraform.rc (Windows) file with the following contents:
+
+  ```terraform
+  provider_installation {
+
+    dev_overrides {
+        "bpg/proxmox" = "/home/user/go/bin/" # <- put an absolute path where $GOPATH/bin is pointing to in your system.
+    }
+
+    # For all other providers, install them directly from their origin provider
+    # registries as normal. If you omit this, Terraform will _only_ use
+    # the dev_overrides block, and so no other providers will be available.
+    direct {}
+  }
+  ```
+
+- Build & install the provider by running the following command in the provider directory:
+
+  ```bash
+  go install .
+
+  ```
+
+- Run `terraform init` in a directory containing a Terraform configuration
+  using the provider. You should see output similar to the following:

+  │
+  │ Skip terraform init when using provider development overrides. It is not necessary and may error unexpectedly.
+  ╵
+
+  Terraform has been successfully initialized!
+  ```
+
+- Run `terraform plan` or `terraform apply` to test your changes.
+
+> [!TIP]
+> You don't need to run `terraform init` again after making changes to the provider, as long as you have the `dev_overrides` block in your `terraform.rc` file, and the provider is installed in the path specified in the `dev_overrides` block by running `go install .` in the provider directory.
