+## Installing additional language packs
+
+By default, this container packs a generic English version of Moodle. Nevertheless, more Langage Packs can be added to the default configuration using the in-platform Administration [interface](https://docs.moodle.org/38/en/Language_packs#Language_pack_installation_and_uninstallation). In order to fully support a new Language Pack it is also a requirement to update the system's locales files. We highly recommend [extending](https://github.com/bitnami/bitnami-docker-moodle#extend-this-image) the default image and adding as many locales as needed:
+
+  ```Dockerfile
+  FROM bitnami/moodle
+  RUN echo "es_ES.UTF-8 UTF-8" >> /etc/locale.gen && locale-gen
+  ```
+
+Bear in mind that in the example above `es_ES.UTF-8 UTF-8` is the locale needed for the desired Language Pack to install. You may change this value to the locale corresponding to your pack.
