+Welcome to your Linux VM!
+
+This VM is pre-configured with the following tools:
+- XFCE Desktop Environment
+- Azure Storage Explorer
+- RStudio Desktop
+- Docker
+- Anaconda
+
+To get started:
+1. Open any application using the Applications Menu.
+2. Use RStudio or Jupyter Notebook for data analysis.
+3. Access your shared file storage at /fileshares/vm-shared-storage (if configured).
+4. See the package mirror options by accessing http://nexus-tvstre.uksouth.cloudapp.azure.com
+
+Recommendations:
+1. R packages may fail to install initially. If you see an error, edit Rprofile to use the local package mirror:
+
+sudo nano /usr/lib/R/etc/Rprofile.site
+
+Replace the local(...) lines at the bottom with:
+local({
+    r <- getOption("repos")
+    r["Nexus"] <- "http://nexus-tvstre.uksouth.cloudapp.azure.com/repository/r-proxy/"
+    options(repos = r)
+})
+
+2. Disable XFCE Lock Screen otherwise you may get locked out:
+
+Open Applications > Settings > Screensaver; click on Lock Screen tab, disable the Lock Screen.
+
+
+For further assistance, contact your administrator.
+
+Enjoy!
