Best Practices

Thesis writing guidelines:
  1. Start early: Set up your document structure before writing
  2. Version control: Use Git to track changes
  3. Regular backups: Keep multiple backups in different locations
  4. Consistent style: Define custom commands for repeated elements
  5. Compile often: Catch errors early
  6. Separate content: One file per chapter
  7. Comments: Document complex LaTeX code
  8. Templates: Check if your university provides a template

​
