 ## Setup of web server
-Two instances of photodiag-web server are hosted on sf-phmon-01.psi.ch virtual machine, both available only from beamline networks/control rooms:
-- https://sf-photodiag.psi.ch (main server)
-- https://sf-photodiag-test.psi.ch (test server)
+
+Two instances of the **photodiag-web** server are hosted on the **sf-phmon-01.psi.ch** virtual machine, both accessible only from the beamline networks/control rooms:
+
+- **Production server**: [https://sf-photodiag.psi.ch](https://sf-photodiag.psi.ch)  
+- **Test server**: [https://sf-photodiag-test.psi.ch](https://sf-photodiag-test.psi.ch)
+
 ### Server updates
-The service is hosted at https://gitlab.psi.ch/photon-diagnostics/photodiag_web
-- Pushing a commit on the main branch will update the test server
-- Pushing a tagged commit on the main branch will update both the test and prod servers. 
 
-To push a release to the main server
-1. git pull the latest tested and operational version
-1. python make_release.py <patch/minor/major>
-1. git push origin main --tags
+- The service repository is hosted at: [https://gitlab.psi.ch/photon-diagnostics/photodiag_web](https://gitlab.psi.ch/photon-diagnostics/photodiag_web)  
+- **Pushing a commit** on the `main` branch updates the **test server**.  
+- **Pushing a tagged commit** on the `main` branch updates **both** the test and production servers.
 
-The release status can be checked via gitlab CI/CD pipelines
+To push a **release** to the main server:
+
+1. Pull the latest tested and operational version:
+
+    git pull
+
+2. Create a new release (choose one of `patch`, `minor`, or `major`):
+
+    python make_release.py patch
+
+3. Push the new tag(s):
+
+    git push origin main --tags
+
+You can check the release status via **GitLab CI/CD pipelines**.
 
 ### Server logs
 
-When on either sf-phmon-01 or sf-phmon-02 use the following:
+When logged into either **sf-phmon-01** or **sf-phmon-02**, you can view logs with:
 
-`sudo journalctl -u photodiag-<test|prod> -e  `
+    sudo journalctl -u photodiag-<test|prod> -e
 
-use either `test` or `prod`
+Replace `<test|prod>` with the desired instance.
 
-```
-ssh sf-phmon-02 
-sudo -i  
-journalctl -u photodiag-test.service -n 100
-```
-this will show the last 100 lines
+For example, to see the last 100 lines of logs on **sf-phmon-02**:
+
+    ssh sf-phmon-02
+    sudo -i
+    journalctl -u photodiag-test.service -n 100
+
+### Restarting the VM or the service
+
+1. **Restart the entire VM**:
+
+       sudo reboot
+
+2. **Restart a single service** (for example, photodiag test or prod):
+
+       sudo systemctl restart <service_name>.service
+
+Replace `<service_name>` with `photodiag-test` or `photodiag-prod`.
