 You need PHP 5.4 (or newer, PHP 7 is fine) compiled with the following modules (those
 are actually very common and should be available in any reasonable Linux distro):
 
--   PDO with support for PostgreSQL or MySQL depending on the database server used
--   Legacy PostgreSQL or MySQL drivers may be needed for plugins not yet migrated to PDO
+-   PDO with support for PostgreSQL or MySQL depending on the database server used - some distributions need both PDO and database-specific drivers, i.e. php-pgsql
 -   JSON
--   XML (DOMDocument)
+-   XML (DOMDocument, DOMXpath)
 -   mbstring
 -   fileinfo
--   CURL (not required, but highly recommended) OR support for remote fopen()
+
+### Not required, but recommended:
+
+-   CURL (highly recommended, just install it) **OR** support for remote fopen()
 -   POSIX functions (for the multiprocess update daemon, otherwise not needed)
 -   GD (needed for OTP and some plugins)
 
 ### Notes:
 
+* Some kind of opcode cache/accelerator is recommended (depends on PHP version/distro: php5-apc, php7-opcache, etc)
 * If your PHP install is missing any of the required modules tt-rss should notify you on startup.
-* Enabling PHP built-in opcode cache or some other kind of accelerator is a good idea.
 * Plugins may have additional dependencies i.e. several bundled plugins require CURL.
 * **PHP safe mode is not supported.**
+
+### Debian 9 example:
+
+<code>
+# apt install php7.0-cli php7.0-curl php7.0-mbstring php7.0-json php7.0-gd php7.0-pgsql php7.0-xml php7.0-opcache
+</code>
+
+If you're starting from scratch you will also likely need several other packages, including httpd and FPM.
