+As of November 2013 all public servers operate this way.
+Please see HOWTO.md for more detailled information. The following is a

 __________________________________________________________
-1. patch and compile bitcoind.
+1. Run bitcoind.
 
-Install version 0.8 or equivalent.
-Patch it with the patch distributed with Electrum.
+Install version 0.8.5 or higher.
+There is no need to patch bitcoind anymore.
+You need to run it with the config option txindex=1 .
+If you have not previously done so, you may need to reindex the bitcoind blockchain
 
 Note: Even though Electrum's database uses pruning, you cannot use it
-with a pruning bitcoind. A full bitcoin node is required in order to
-know for each address if it has been used. Pruning occurs only at the
-level of the Electrum database.
+with a ultra-pruning bitcoind (forthcoming in 0.9 or later).

 2. Install python-leveldb: 
 
+Starting at Ubuntu 12.10 you can use apt to install leveldb. If you 
+rather stay on 12.04 LTS you can use the backport and add 
+"deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe"
+to your sources file. Install the package with: 
+
 sudo apt-get install python-leveldb
 
 alternatively build yourself, see
