What do the 'Choose files to document' filter options mean?

Short Answer: 'Pick my own files' = manual selection; 'Recently merged' = files changed in recent merges; 'Undocumented' = files without prior documentation; 'Documented' = files with a last documented date; 'All files in the repository' = every file.

Steps

1. Open the 'Choose files to document' dropdown to view options.
   Dropdown displays: 'Pick my own files', 'Recently merged', 'Undocumented', 'Documented', 'All files in the repository'.

2. Select each option to observe how the file list changes (example screens provided).
   'Recently merged' shows recently merged files.

3. Select 'Undocumented' or 'Documented' to view files marked by documentation status.
   'Undocumented' shows files without documentation; 'Documented' shows files with a last documented date.

4. Select 'All files in the repository' to include everything.
   The file list reflects all repository files.

Troubleshooting

1. A filter returns no files.
   LikelyCause: Branch or the filter excludes files.
   Action: Switch branch or choose 'All files in the repository'.

Note: Filter labels appear exactly as: 'Pick my own files', 'Recently merged', 'Undocumented', 'Documented', 'All files in the repository'.
