+<!-- Describes what this module does -->
+
+```tf
+module "github-upload-public-key" {
+  source   = "registry.coder.com/modules/github-upload-public-key/coder"
+  version  = "1.0.13"
+  agent_id = coder_agent.example.id
+}
+```
+
+<!-- Add a screencast or screenshot here  put them in .images directory -->
+
+## Examples
+
+### Example 1
+
+Install the Dracula theme from [OpenVSX](https://open-vsx.org/):
+
+```tf
+module "MODULE_NAME" {
+  source     = "registry.coder.com/modules/MODULE_NAME/coder"
+  version    = "1.0.2"
+  agent_id   = coder_agent.example.id
+  extensions = [
+    "dracula-theme.theme-dracula"
+  ]
+}
+```
+
+Enter the `<author>.<name>` into the extensions array and code-server will automatically install on start.
+
+### Example 2
+
+Configure VS Code's [settings.json](https://code.visualstudio.com/docs/getstarted/settings#_settingsjson) file:
+
+```tf
+module "MODULE_NAME" {
+  source     = "registry.coder.com/modules/MODULE_NAME/coder"
+  version    = "1.0.2"
+  agent_id   = coder_agent.example.id
+  extensions = [ "dracula-theme.theme-dracula" ]
+  settings   = {
+    "workbench.colorTheme" = "Dracula"
+  }
+}
+```
+
+### Example 3
+
+Run code-server in the background, don't fetch it from GitHub:
+
+```tf
+module "MODULE_NAME" {
+  source   = "registry.coder.com/modules/MODULE_NAME/coder"
+  version  = "1.0.2"
+  agent_id = coder_agent.example.id
+  offline  = true
+}
+```
