+##Instructions for Debian
+
+The following commands are to be executed as root:
+
+1. In `tox_bootstrap_daemon.sh` file change:
+  - `CFG` to where your config file (`conf`) will be; read rights required
+  - `DAEMON` to point to the executable
+  - `PIDFILE` to point to a pid file daemon would have rights to create
+
+2. Go over everything in `conf`. Make sure `pid_file_path` matches `PIDFILE` from `tox_bootstrap_daemon.sh`
+
+3. Execute: 
+```
+mv tox_bootstrap_daemon.sh /etc/init.d/tox_bootstrap_daemon
+```
+*(note that we removed `.sh` ending)*
+
+4. Give the right permissions to this file: 
+```
+chmod 755 /etc/init.d/tox_bootstrap_daemon
+```
+
+5. Execute: 
+```
+update-rc.d tox_bootstrap_daemon defaults
+```
+
+6. Start the service: 
+```
+service tox_bootstrap_daemon start
+```
+
+7. Verify that the service is running: 
+```
+service tox_bootstrap_daemon status
+```
+
+--
+
+You can see daemon's log with
+```
+grep "tox_bootstrap_daemon" /var/log/syslog
+```
+
+**Note that system log is where you find your public key**
+
+--
+
+###Troubleshooting:
+
+1. Check the log for errors with 
+```
+grep "tox_bootstrap_daemon" /var/log/syslog
+```
+
+2. Check that paths in the beginning of `/etc/init.d/tox_bootstrap_daemon` are valid
+
+3. Make sure that `PIDFILE` from `/etc/init.d/tox_bootstrap_daemon` matches with the `pid_file_path` from `conf`
+
+4. Make sure you have write permission to keys and pid files
+
+5. Make sure you have read permission for config file
