+### Configuration for executing mTCP sample application "HTTP server"
 1. Configure static ARP entries
 
     .../mtcp-devel/apps/example/config$ vim arp.conf 
 
     //Add ARP entries for remote IPs (see example below)
     
-        ```ARP_ENTRY 6
+        ARP_ENTRY 6
         192.168.200.10/32 0c:42:a1:df:ac:48

+2. Configure static route entries 
+
+    .../mtcp-devel/apps/example/config$ vim route.conf 
+    
+    //Add route entries for remote IPs (see example below)
+    
+        ROUTES 2

+        192.168.200.0/24 ens259f1
+        
+3. Configure HTTP server application 
+    
+    .../mtcp-devel/apps/example$ vim epserver.conf
+    
+    - num_cores = 4 //set the number of cores that will run mTCP
+    - core_mask = 0F // bit-mask that specifies which cores to use; 0F=00001111; use cores 0-3
+    - num_tx_desc = 512 //set TX descriptor ring size
+    - num_rx_desc = 128 //set RX descriptor ring size
+    - port = p0 //set the port that should be mapped for mTCP
+    - stat_print = p0 //set the ports for which stats should be printed
+
+    You can configure other parameters too for optimized performance
+2. Configure HTTP client application 
+        ..../mtcp-devel/apps/example$ vim epwget.conf
+
+    Configure the client-side mTCP for the parameters listed in step (1)
+    
+### Execute mTCP sample application "HTTP server"
+1. Configure the RTE vars
+    
+    $ export RTE_SDK=<absolute-path-to-dpdk-stable-19.11.8>
+    
+    $ export RTE_TARGET=<target>
+2. For mTCP based HTTP server
+    a. Create a directory where files that are requested for transfer are stored
+    b. Run the HTTP server
+        
+    .../mtcp-devel/apps/example$ sudo ./epserver -p <absolute-path-to-www-dir> -f epserver.conf [-N <num-cores>]
+    
+    Example:
+
+    ~/mtcp-devel/apps/example$ sudo ./epserver -p /home/ubuntu/www -f epserver.conf -N 2
+3. For mTCP based HTTP client
+
+    .../mtcp-devel/apps/example$ sudo ./epwget <server-IP>/<file-name> <num_requests> [-N #cores] [-c concurrency] -f epwget.conf
+
+    Example:
+
+    ~/mtcp-devel/apps/example$ sudo ./epwget 192.168.220.35/example.txt 10000000 -N 8 -c 10000 -f epwget.conf
