+
+# Hashicorp Vault Integration (Token)
+
+This module lets you authenticate with [Hashicorp Vault](https://www.vaultproject.io/) in your Coder workspaces using a [Vault token](https://developer.hashicorp.com/vault/docs/auth/token).
+
+```tf
+variable "vault_token" {
+  type        = string
+  description = "The Vault token to use for authentication."
+  sensitive   = true
+}
+
+module "vault" {
+  source      = "registry.coder.com/modules/vault-token/coder"
+  version     = "1.0.3"
+  agent_id    = coder_agent.example.id
+  vault_token = var.token
+  vault_addr  = "https://vault.example.com"
+}
+```
+
+Then you can use the Vault CLI in your workspaces to fetch secrets from Vault:
+
+```shell
+vault kv get -namespace=coder -mount=secrets coder
+```
+
+or using the Vault API:
+
+```shell
+curl -H "X-Vault-Token: ${VAULT_TOKEN}" -X GET "${VAULT_ADDR}/v1/coder/secrets/data/coder"
+```
+
+## Configuration
+
+To configure the Vault module, you must create a Vault token with the the required permissions and configure the module with the token and Vault address.
+
+1. Create a vault policy with read access to the secret mount you need your developers to access.
+   ```shell
+   vault policy write read-coder-secrets - <<EOF
+    path "coder/data/*" {
+      capabilities = ["read"]
+    }
+    path "coder/metadata/*" {
+      capabilities = ["read"]
+    }
+    EOF
+   ```
+2. Create a token using this policy.
+   ```shell
+   vault token create -policy="read-coder-secrets"
+   ```
+3. Copy the generated token and use in your template.
+
+## Examples
+
+### Configure Vault integration and install a specific version of the Vault CLI
+
+```tf
+variable "vault_token" {
+  type        = string
+  description = "The Vault token to use for authentication."
+  sensitive   = true
+}
+
+module "vault" {
+  source            = "registry.coder.com/modules/vault-token/coder"
+  version           = "1.0.3"
+  agent_id          = coder_agent.example.id
+  vault_addr        = "https://vault.example.com"
+  vault_token       = var.token
+  vault_cli_version = "1.15.0"
