 INSTALLATION NOTES
-1. Set up MySQL and memcached. We run memcached with the command:
-	memcached -d -m 5120 -s /var/run/memcached.sock -a 0777 -t16 -C -u root
-	This gives it 5 gigs of RAM; you probably want to set that a bit lower!
+1. Set up MySQL and memcached. memcached can be started with the command:
+	memcached -d -m 5120 -s /var/run/memcached.sock -a 0777 -t4 -C -u nobody
+	This starts 4 threads and gives it 5 gigs of RAM
 2. Run gazelle.sql (preferably as root) to create the database, the table, and the default data.
 3. Install Sphinx - we recommend you use the included sphinx.conf. You can copy this to
     /etc/sphinx/sphinx.conf. You need to fill in the details of the SQL server though!
 
-    You might also need to create the /var/data/sphinx folder.
