-## Usage 
-To run the project use the `start` command defined in package.json:
+### Optional
+Can also set `pdfFilename` to overwrite filename prefix (default: `telenor-downtime`).
 
+# Usage
+We have two commands `start` & `scrape`. Start boots calls express server to start to server webpage for visual representation of data; and Scrape for checking and logging contents of ISP monitor page.
+
+Start the webserver:
 ```bash
 yarn start
 ```
+Open http://localhost:3000/ in your browser.
+
+Run the scraper:
+```bash
+yarn scrape
+```
+This saves a pdf of the page to `pdfExports/` within the project folder, and logs the uptime status to db.
+
+# Running as a service
+If on any linux platform you should have `systemd` installed. We want to create a service that both runs & restarts our webserver if necessary and want a scheduled job to run for scraping.   
+
+Remember to replace `YOUR_PROJECT_DIRECTORY` w/ the full path to where you have the `ISPDowntimeMonitor/` folder.   
+
+Main server start service:
+```
+# /etc/systemd/system/ispmonitor.service

+Description=ISP monitor daemon
+Wants=isp-scraper.timer
