Build and inspect your PDF
Use the build action to turn your current LaTeX project into a PDF you can review.
Open the document you want to build
Make sure the main .tex file for the document is open in your project.

Choose Build from the toolbar. TeX64 updates the PDF when the build succeeds.
Use the result to guide your next edit
Read the PDF or build message, make the next change in source, and build again.
