+If you cannot access Kimchi, take a look at these 2 points:
+
+1. Firewall
+Kimchi uses by default the ports 8000, 8001 and 64667. To allow incoming connections:
+
+    For system using firewalld, do:
+    sudo firewall-cmd --add-port 8000 --permanent
+    sudo firewall-cmd --add-port 8001 --permanent
+    sudo firewall-cmd --add-port 64667 --permanent
+    sudo firewall-cmd --reload
+
+    For openSUSE systems, do:
+    sudo /sbin/SuSEfirewall2 open EXT TCP 8000
+    sudo /sbin/SuSEfirewall2 open EXT TCP 8001
+    sudo /sbin/SuSEfirewall2 open EXT TCP 64667
+
+    For system using iptables, do:
+    sudo iptables -A INPUT -p tcp --dport 8000 -j ACCEPT
+    sudo iptables -A INPUT -p tcp --dport 8001 -j ACCEPT
+    sudo iptables -A INPUT -p tcp --dport 64667 -j ACCEPT
+
+    Don't forget to correctly save the rules.
+
+
+2. SELinux
+Allow httpd_t context for Kimchi web server:
+
+    semanage permissive -a httpd_t
