+    sudo apt install php5-dev  libsystemd-dev
+
+.rpm based
+
+    sudo dnf install php-devel systemd-devel
+
+### Build

     phpize
     ./configure --with-systemd
     make

+### Setup

+
+### Basic Test

     echo "<?php echo sd_journal_send('MESSAGE=hello world');" | php

+
 Usage
-=====
+-----
 
 Quick example:
 
-    <?php
-    sd_journal_send('MESSAGE=Hello world.');
-    sd_journal_send('MESSAGE=Hello, again, world.', 'FIELD2=Greetings!', 'FIELD3=Guten tag.');
-    sd_journal_send('ARBITRARY=anything', 'FIELD3=Greetings!');
+``` {.php}
+<?php
+sd_journal_send('MESSAGE=Hello world.');
+// message with priority "3" (warning) and identifier (also called *TAG*) set to "appname" 
+sd_journal_send('MESSAGE=Error message','PRIORITY=3', 'SYSLOG_IDENTIFIER=appname');"
+```
 
 Notes:
 
- * Each argument must be in the form of a KEY=value pair, environmental variable style.
- * Unlike the native C version of journald's sd_journal_send(), printf-style substitution is not supported. Perform any substitution using PHP's sprintf() or similar capabilities first.
- * The base message is usually sent in the form MESSAGE=hello. The MESSAGE field is, however, not required.
- * Invalid arguments result in nothing recorded in the journal.
