 **Step 1:**
 
+By default these changes should have already been made as part of your node setup but incase they're not, you can follow the steps below
+
 You will need to change `prometheus` flag to `true` in the `config.toml`. 
 
 To access the config.toml here:
 
-**Linux Packages**: `sudo vi /etc/heimdall/config/config.toml`
-**Binaries**: `vi ~/.heimdalld/config/config.toml`
-
-By default the prometheus flag is set to `false`.
+`vi ~/.heimdalld/config/config.toml`
 
 Make sure that you keep the formatting intact.
 
 **Step 2:**
 
-Once you have made the changes in the `config.toml` you will need to stop Heimdall service and restart it.
+Once you have made the changes in the `config.toml` you will need to stop Heimdall service and restart it. Note that you only need to restart Heimdall service if you have made changes to it.
 
 To stop heimdall service:
 
-**Linux Packages**: `sudo service heimdalld stop`
-**Binaries**: `pkill heimdalld`
+`sudo service heimdalld stop`
 
 To restart heimdall service:
 
-**Linux Packages**: `sudo service heimdalld start`
-**Binaries**: `heimdalld start`
+`sudo service heimdalld start`
 
 **Step 3:**
 
 You will make changes in the Bor service file. To access the `bor.service` file you can run this command:
 
-`locate bor.service`
+`nano /home/ubuntu/node/bor/start.sh`
 
-There would be multiple entries. You will need to edit the file in this system path: `/etc/systemd/system/bor.service`
+There would be multiple entries. By default the following parameters should be automatically added, but if they're not added then you can the parameters from below.
 
-To edit the service file you can run the following command:
+Now in this you would see multiple paramaters in a list format. Add this in the following format. You can add it anywhere, for example, you can add it after `--maxpeers 150`
 
-`sudo nano /etc/systemd/system/bor.service`
+```js
+--metrics \
+--pprof --pprofport 7071 --pprofaddr '0.0.0.0' \
+``` 
 
-Now in this you would see `ExecStart=/bin/bash` with multiple paramaters in line to it. Add this, `--metrics --pprof --pprofport 7071 --pprofaddr 0.0.0.0` to this line of paramaters. You can add it anywhere, for example, you can add it after `--maxpeers 150`
+Note that these parameters should already be added as part of your setup. You only need to add these parameters if they're not already present in the `start.sh` file. 
 
 You need to make sure that the spaces and formatting are intact.
 
 Now you will notice that your bor will stop because we made changes to the service file. You will need to stop the bor service and restart it.
 
 To Stop Bor service:
 
-**Linux Packages**: `sudo service bor stop`
-**Binaries**: `pkill bor`
+`sudo service bor stop`
 
 Note: When you stop the service of Bor you may encounter a warning asking you run `systemctl daemon-reload` to reload units.
 
 You will need to run this as `sudo systemctl daemon-reload`. Once this is successfull you can proceed with starting the Bor service.
 
 To Restart Bor service:
 
-**Linux Packages**: `sudo service bor start`
-**Binaries**: `bash start.sh <Your Ethereum wallet address>`
+`sudo service bor start`
 
-Note: You will need to use the same Address that you used when you had initially set up your node.
