 There are a few proof of concept example applications for usage of the API at https://litcal.johnromanodorazio.com/usage.php, which demonstrate generating an HTML representation of the Liturgical Calendar.
 
 * The [first example](https://litcal.johnromanodorazio.com/examples/php/) uses cURL in PHP to make a request to the endpoint and handle the results.
-* The [second example](https://litcal.johnromanodorazio.com/examples/javascript/) uses AJAX in Javascript to make the request to the endpoint and handle the results.
-* The [third example](https://litcal.johnromanodorazio.com/examples/fullcalendar/examples/month-view.html) makes use of the [FullCalendar javascript framework](https://github.com/fullcalendar/fullcalendar) to display the results from the AJAX request in a nicely formatted calendar view.
+* The [second example](https://litcal.johnromanodorazio.com/examples/javascript/) uses `fetch` in Javascript to make the request to the endpoint and handle the results.

 * The [fourth example](https://litcal.johnromanodorazio.com/examples/fullcalendar/examples/messages.html) is the same as the third except that it outputs the Messages first and the [FullCalendar](https://github.com/fullcalendar/fullcalendar) calendar view after.
 
 All of these examples request `JSON` as the data exchange format generated by the endpoint. Any application could use the endpoint in a similar manner: an Android App, a plugin for a Desktop Publishing App...

 # Testing locally
 
+System requirements:
+* PHP >= 8.1
+* PHP modules installed and enabled: `intl` * `zip` * `gettext` * `calendar` * `yaml`
+* System language packs for all the supported languages
+
+## Using PHP's builtin server
+
 To test the API locally, you can use PHP's builtin server. However, you will need to spawn at least a couple of workers, since some routes will make a request internally to another route. For example, a request to the `/calendar` route will make a request internally to the `/calendars` route.
 
 Spawn at least two workers:
 ```bash
 PHP_CLI_SERVER_WORKERS=2 php -S localhost:8000
 ```
 
+## Using a docker container
+
 For convenience when using VSCode, a `tasks.json` has been defined so that you can simply type <kbd>CTRL</kbd>+<kbd>SHIFT</kbd>+<kbd>B</kbd> (<kbd>CMD</kbd>+<kbd>SHIFT</kbd>+<kbd>B</kbd> on MacOS) to start the PHP builtin server and open the browser.
 
+To further simplify your setup, without having to worry about getting all the system requirements in place, you can also launch the API in a docker container using the repo `Dockerfile`:
+
+```bash
+# If you haven't cloned the repo locally, you can build directly from the remote repo (replace `{branch}` with the branch or tag from which you want to build):
+docker build -t liturgy-api:{branch} https://github.com/Liturgical-Calendar/LiturgicalCalendarAPI.git#{branch}
+# If instead you have cloned the repo locally, you can build from the local repo (replace `{branch}` with the branch or tag that you have checked out locally):
+docker build -t liturgy-api:{branch} .
+docker run -p 8000:8000 -d liturgy-api:{branch}
+```
