+### Install other requirements
+
+Some operations in OpenProject require additional software. These include PDF exports and interaction with an
+LDAP server.
+
+In order to develop OpenProject in these areas, you need to install `imagemagick` and `java`.
+
+```shell
+brew install imagemagick java

+
+As of writing, you need to manually create a symlink to OpenJDK for the Java installation to take effect. Homebrew will

 ### Finish the Installation of OpenProject
 
 Install code dependencies, link plugin modules and export translation files.
