+#### Using systemd  
+
+Run below command in terminal:  
+```
+sudo vim /etc/systemd/system/gitea.service
+```  
+
+Add code to the file from [here](https://github.com/go-gitea/gitea/blob/master/contrib/systemd/gitea.service).  
+
+Uncomment any service need to be enabled like mysql in this case in Unit section.  
+
+Change the user(git) accordingly to yours. And /home/git too if your username is different than git. Change the PORT or remove the -p flag if default port is used.  
+
+Lastly start and enable gitea at boot:  
+```
+sudo systemctl start gitea
+```  
+```
+sudo systemctl enable gitea
+```  
+
+
 #### Using supervisor  
 
 Install supervisor by running below command in terminal:  
-```sudo apt install supervisor```  
+```
+sudo apt install supervisor
+```  
 
 Create a log dir for the supervisor logs(assuming gitea is installed in /home/git/gitea/):  
-```mkdir /home/git/gitea/log/supervisor```  
+```
+mkdir /home/git/gitea/log/supervisor
+```  
 
 Open supervisor config file in vi/vim/nano etc.  
-```sudo vim /etc/supervisor/supervisord.conf```  
-
-And append the following code at the end of the file, [reference](https://github.com/go-gitea/gitea/blob/master/contrib/supervisor/gitea):  
-```
-[program:gitea]
-directory=/home/git/gitea/
-command=/home/git/gitea/gitea web -p PORT
-autostart=true
-autorestart=true
-startsecs=10
-stdout_logfile=/home/git/gitea/log/supervisor/stdout.log
-stdout_logfile_maxbytes=1MB
-stdout_logfile_backups=10
-stdout_capture_maxbytes=1MB
-stderr_logfile=/home/git/gitea/log/supervisor/stderr.log
-stderr_logfile_maxbytes=1MB
-stderr_logfile_backups=10
-stderr_capture_maxbytes=1MB
-user = git
-environment = HOME="/home/git", USER="git"
+```
+sudo vim /etc/supervisor/supervisord.conf
 ```  
 
+And append the code at the end of the file from [here](https://github.com/go-gitea/gitea/blob/master/contrib/supervisor/gitea).  
+
 Change the user(git) accordingly to yours. And /home/git too if your username is different than git. Change the PORT or remove the -p flag if default port is used.
