Timeline.
I found that the most cohesive way to tie everything together was to document my internship by writing a summary of each week. These timeline posts were written mostly in hindsight and generated from my journal entries, a detailed timesheet, and any relevant screenshots/media.
They will generally follow the following format: Number of internship hours that week, a brief outline of what I spent time working on, and the relevant tags for themes and tools with brief thoughts in those areas.
