+Docker images built on top of the [official PHP images](https://hub.docker.com/r/_/php/) with the addition of some common and useful extensions, installed with [mlocati/docker-php-extension-installer](https://github.com/mlocati/docker-php-extension-installer), and are meant for *continuout integration purposes*. You can find these images on the [Docker Hub](https://hub.docker.com/r/chialab/php-otel/) (and if you're reading this file, you're probably already there).
+
+An automated build is set up, so they should be always up-to-date with the Dockerfiles in the [GitHub repository](https://github.com/chialab/docker-php). Also, every time an official PHP image is updated, a rebuild is triggered, so that you will always find the latest security patches installed in these images.
+
+## Available tags
+- `latest`
+- `8.0`
+- `8.0-apache`
+- `8.0-fpm`
+- `8.1`
+- `8.1-apache`
+- `8.1-fpm`
+- `8.2`

+- `8.3`
+- `8.3-apache`
+- `8.3-fpm`
+- `8.4`
+- `8.4-apache`
+- `8.4-fpm`
+
+As you might have guessed, all tags are built on top of the corresponding tag of the official image. Not all tags are supported in order to easen maintenance.
+
+## Installed extensions
+The following modules and extensions have been enabled,
+in addition to those you can already find in the [official PHP image](https://hub.docker.com/r/_/php/):
+
+- `amqp`
+- `bcmath`
+- `bz2`
+- `calendar`
+- `event`
+- `exif`
+- `gd`
+- `gettext`
+- `iconv`
+- `imagick`
+- `intl`
+- `ldap`
+- `mbstring`
+- `mcrypt` (_only PHP ≤ 7.1_)
+- `memcached`
+- `mysql` (_only PHP 5.x_)
+- `mysqli`
+- `opentelemetry`
+- `pdo_mysql`
+- `pdo_pgsql`
+- `pgsql`
+- `redis`
+- `soap`
+- `sockets`
+- `xsl`
+- `Zend OPcache`
+- `zip`
+
+You will probably not need all this stuff. Even if having some extra extensions loaded ain't a big issue in most cases (especially in a development environment), you will very likely want to checkout this repository, remove unwanted extensions from the `Dockerfile`, and build your own image — for sometimes removing is easier than adding. 😉
+
+## Composer
+[Composer](https://getcomposer.org) is installed globally in all images. Please, refer to their documentation for usage hints.
+Since 2020/11/01 both version 1 and 2 are installed, available through `composer1` and `composer2` commands respectively (`composer` in now a symlink to `composer2`).  
+[Prestissimo (composer plugin)](https://github.com/hirak/prestissimo) is installed globally in all images, for use with Composer version 1. It's a plugin that downloads packages in parallel to speed up the installation process of Composer packages.
+
+## Contributing
+If you find an issue, or have a special wish not yet fulfilled, please [open an issue on GitHub](https://github.com/chialab/docker-php/issues) providing as many details as you can (the more you are specific about your problem, the easier it is for us to fix it).
+
+Pull requests are welcome, too! 😁 Please, run `make build` and `make test` before attempting a pull request. Also, it would be nice if you could stick to the [best practices for writing Dockerfiles](https://docs.docker.com/articles/dockerfile_best-practices/).
