+# Remote Development on Oracle Cloud Infrastructure (OCI)
+
+Provision OCI VMs as [Coder workspaces](https://coder.com/docs/workspaces) with this template.
+
+## Prerequisites
+
+### Oracle Cloud Infrastructure Account
+You need an active OCI account.
+
+### Required Variables
+To use this template, you must provide the following variables. These can be found in your OCI Console.
+
+1.  **tenancy_ocid**: The OCID of your tenancy. Found in **Governance & Administration** -> **Tenancy Details**.
+2.  **user_ocid**: The value of the specific user's OCID. Found in **Identity** -> **Users**.
+3.  **fingerprint**: Create an API key for the user (in **User Details** -> **API Keys**) and get the fingerprint.
+4.  **private_key_path**: The local path to the private key file corresponding to the public key you uploaded. This path must be accessible by the Coder server or provisioner.
+5.  **region**: Your OCI region (e.g., `us-ashburn-1`).
+6.  **compartment_ocid**: The OCID of the compartment where resources will be created.
+7.  **image_id**: The OCID of the Linux image (e.g., Ubuntu 22.04) you want to use.
+    *   Go to **Compute** -> **Platform Images** to find the generic image OCID for your region (e.g. `Canonical Ubuntu`).
+
+## Resources Created
+- VCN, Subnet, Internet Gateway, Route Table
+- OCI Compute Instance (default shape: VM.Standard.A1.Flex)
