See Photon OS 5 Documentation.pdf

Inside the docs pdf,

• broken weblinks
• broken photos
• command cuts in console windows
• a few markup issues and wrongly indented text
• add page number, title

For page/description, see Notes.txt.

From a content perspective, add

• security features overview, see e.g. https://fedoraproject.org/wiki/Security_Features_Matrix
• modernized chapters for (build) prerequisites (who is still using Ubuntu 14, VMware webclient v6.5 or ESXi 6.7?)
• Secure Boot on VVF, and on AWS/GCE/Azure
• chapter about crafting Photon OS templates on AWS/GCE/Azure, separated to provision/delete vm
• POI description
