 Remember, you must install dependencies for your extensions manually. If an extension needs custom `configure` arguments, you can use the `docker-php-ext-configure` script like this example. There is no need to run `docker-php-source` manually in this case, since that is handled by the `configure` and `install` scripts.
 
-See ["Dockerizing Compiled Software"](https://tianon.xyz/post/2017/12/26/dockerize-compiled-software.html) for a description of the technique Tianon uses for determining the necessary build-time dependencies for any bit of software (which applies directly to compiling PHP extensions).
+If you are having difficulty figuring out which Debian or Alpine packages need to be installed before `docker-php-ext-install`, then have a look at [the `install-php-extensions` project](https://github.com/mlocati/docker-php-extension-installer). This script builds upon the `docker-php-ext-*` scripts and simplifies the installation of PHP extensions by automatically adding and removing Debian (apt) and Alpine (apk) packages. For example, to install the GD extension you simply have to run `install-php-extensions gd`. This tool is contributed by community members and is not included in the images, please refer to their Git repository for installation, usage, and issues.
