+# nodejs
+
+Automatically installs [Node.js](https://github.com/nodejs/node) via [nvm](https://github.com/nvm-sh/nvm). It can also install multiple versions of node and set a default version. If no options are specified, the latest version is installed.
+
+```tf
+module "nodejs" {
+  source   = "registry.coder.com/modules/nodejs/coder"
+  version  = "1.0.2"
+  agent_id = coder_agent.example.id
+}
+```
+
+### Install multiple versions
+
+This installs multiple versions of Node.js:
+
+```tf
+module "nodejs" {
+  source   = "registry.coder.com/modules/nodejs/coder"
+  version  = "1.0.2"
+  agent_id = coder_agent.example.id
+  node_versions = [
+    "18",
+    "20",
+    "node"
+  ]
+  default_node_version = "20"
+}
+```
+
+### Full example
+
+A example with all available options:
+
+```tf
+module "nodejs" {
+  source             = "registry.coder.com/modules/nodejs/coder"
+  version            = "1.0.2"
+  agent_id           = coder_agent.example.id
+  nvm_version        = "v0.39.7"
+  nvm_install_prefix = "/opt/nvm"
+  node_versions = [
+    "16",
+    "18",
+    "node"
+  ]
+  default_node_version = "16"
+}
+```
