TortoiseGit installed. Git Windows installed.
I created a new repository in Bitbucket.
git init
git remote add origin https:// etc.
Created a small file.
In File Explorer, right-click file, TortoiseGit -> Add.
In File Explorer, right-click parent subdirectory, TortoiseGit -> (no commit menu option).
How does one commit a file using the context menu for TortoiseGit?
See the following screenshot of a context menu. The TortoiseGit commit entry is directly above the TortoiseGit submenu entry.
Please beware, that the TortoiseGit menu is configurable and you can hide entries. Hold the shift-key while opening the context menu to see all available commands.
