+# Kirby autopublish plugin
+
+Kirby 3 plugin to schedule the automatic publishing of pages (drafts) on a certain date+time.
+It is built to work with enabled cache.
+
+## Installation
+
+- unzip [master.zip](https://github.com/bvdputte/kirby-autopublish/archive/master.zip) as folder `site/plugins/kirby-autopublish` or
+- `git submodule add https://github.com/bvdputte/kirby-autopublish.git site/plugins/kirby-autopublish` or
+- `composer require bvdputte/kirby-autopublish`
+
+⚠️ Highly recommended to also install the [kirby-log plugin](https://github.com/bvdputte/kirby-log), to get page-publication logs.
+
+## Usage
+
+### Setup worker
+
+#### 1. Via Cron
+
+Add the worker file `site/plugins/kirby-autopublish/worker.php` to [cron](https://en.wikipedia.org/wiki/Cron) or similar at the desired interval (.e.g. each minute).
+
+💡 This is the preferred method for setting up kirby-autopublish.
+
+#### 2. Poor man's cron
+
+When cron is not installed on your server, you can _fake_ cron by [enabling this](#options-and-opinionated-defaults) in `config.php`.
+
+### Setup field in blueprint
+
+```yaml
+autopublish:
+  label: Autopublish on
+  type: date
+  time: true
+  default: now
+```
+
+## Options and opinionated defaults
+
+Set in `config.php`:
+
+### Field name
+
+Autopublish searches for a date-field. By default the name is `autopublish`, but can be changed:
+
+```php
+'fieldName' => 'myautopublishfieldname'
+```
+
+### Poor man's cron
+
+By default, this is disabled. Enable:
+
+```php
+// Enable poor man's cron
+'bvdputte.kirbyAutopublish.poormanscron' => true
+```
+
+The default interval for poor man's cron to check is each minute. Change this to e.g. quarterly:
+
+```php
+'bvdputte.kirbyAutopublish.poormanscron.interval' => 15
+```
