+---
+
+An experimental plugin that enables cron trigger for Spin applications.
+
+## Installing Plugin
+
+You can install the plugin using the following command:
+
+```bash
+spin plugins install --url https://github.com/fermyon/spin-trigger-cron/releases/download/canary/trigger-cron.json
+```
+
+## Installing Template
+
+You can install the template using the following command:
+
+```bash
+spin templates install --git https://github.com/fermyon/spin-trigger-cron
+```
+
+Once the template is installed, you can create a new application using:
+
+```bash
+spin new -t cron-rust hello_cron --accept-defaults
+```
+
+To run the newly created app:
+
+```bash
+cd hello_cron
+spin build --up
+```
+
+### Configuring the Cron Trigger
+
+The trigger type is `cron` and there are no application-level configuration options.
+
+The following options are available to set in the [[trigger.cron]] section:
+
+| Name                  | Type             | Required? | Description |
+|-----------------------|------------------|-----------|-------------|
+| `component`           | string or table  | required  | The component to run on the schedule given in `cron_expression`. (This is the standard Spin trigger component field.) |
+| `cron_expression`     | string           | required  | The `cron` expression describing the schedule on which to execute the component. |
+
+```toml
+[[trigger.cron]]
+component = "<your-component-name>"
+cron_expression = "1/2 * * * * *"
+```
