+SYSTEMD SUPPORT IN BITCOIN
+==========================
+
+Packagers can find a .service file in this repo in order to integrate bitcoin's 
+daemon into systemd based distributions.
+
+bitcoind.service file is located in contrib/systemd/ folder.
+
+1. Users
+---------------------------------
+
+This .service file assumes bitcoind user and group exist in the system, so packager
+should make sure they are created on installation. 
+
+2. Files
+---------------------------------
+
+The .service file assumes several paths that might need to be adjusted according
+to packager's needs.
+
+Daemon's config file is assumed to be located at /etc/bitcoind.conf (you can
+use contrib/debian/examples/bitcoin.conf as an example). Once installed, users
+must edit the file in order to update at least these two 
+values: rpcuser and rpcpassword . Failing to do so will make the daemon fail 
+to boot. However, the message written to /var/lib/bitcoind/debug.log file is
+very helpful and no default values should be set:
+
+    YYYY-MM-DD HH:MM:DD Error: To use the "-server" option, you must set a rpcpassword in the configuration file:
+    /etc/bitcoind.conf
+    It is recommended you use the following random password:
+    rpcuser=bitcoinrpc
+    rpcpassword=HdYZ5HGtAF7mx8aTw6uCATtD2maMAK4E12Ysp4YNZQcX
+    (you do not need to remember this password)
+    The username and password MUST NOT be the same.
+    If the file does not exist, create it with owner-readable-only file permissions.
+    It is also recommended to set alertnotify so you are notified of problems;
+    for example: alertnotify=echo %s | mail -s "Bitcoin Alert" admin@foo.com
+
+Daemon's data and pid files will be stored in /var/lib/bitcoind directory, so it
+should be created on installation and make bitcoind user/group it's owner.
+
+3. Installing .service file
+---------------------------------
+
+Installing this .service file consists on just copying it to /usr/lib/systemd/system
+directory, followed by the command "systemctl daemon-reload" in order to update
+running systemd configuration.
