 ## System Requirements
+- Linux 64-bit Intel/AMD
 
-- Linux-amd64
+> :warning: The following commands are executed with root privileges, if the prompt `Permission denied` appears, you need to switch to root privileges, or add `sudo` at the top of these commands.
 
+## System configuration
+### Install application tools
 
-## System dependencies
-
-Take the ubuntu distribution as an example:
+For the Debian and  ubuntu families of linux systems:
 
 ```shell
-sudo apt update && sudo apt upgrade
-sudo apt install g++ make gcc git curl wget vim screen util-linux -y
+apt install git curl wget vim util-linux -y
 ```
 
-## System configuration
+For the Fedora, RedHat and CentOS families of linux systems:
 
-- Firewall
+```
+yum install git curl wget vim util-linux -y
+```
 
-If the firewall is turned on, you need to open the running port, the default port is 15001.
+### Firewall configuration
+By default, cess-bucket uses port `4001` to listen for incoming connections, if your platform blocks these two ports by default, you may need to enable access to these port.
+
+#### ufw
+For hosts with ufw enabled (Debian, Ubuntu, etc.), you can use the ufw command to allow traffic to flow to specific ports. Use the following command to allow access to a port:
+```
+ufw allow 4001
+```
 
-Take the ubuntu distribution as an example:
+#### firewall-cmd
+For hosts with firewall-cmd enabled (CentOS), you can use the firewall-cmd command to allow traffic on specific ports. Use the following command to allow access to a port:
+```
+firewall-cmd --get-active-zones
+```
+This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is public, use
+```
+firewall-cmd --zone=public --add-port=4001/tcp --permanent
+```
+Note that permanent makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.
+```
+firewall-cmd --reload
+```
 
-```shell
-sudo ufw allow 15001/tcp
+#### iptables
+For hosts with iptables enabled (RHEL, CentOS, etc.), you can use the iptables command to enable all traffic to a specific port. Use the following command to allow access to a port:
 ```
-- Network optimization (optional)
+iptables -A INPUT -p tcp --dport 4001 -j ACCEPT
+service iptables restart
+```
+
+### Network optimization (optional)
 
 ```shell
 sysctl -w net.ipv4.tcp_syncookies = 1
