hg-add:tldr:05778

This command is a Mercurial (hg) command used to add a file to the repository with the specified filename.

Here's a breakdown of the command:

• hg refers to the Mercurial command-line tool used for version control.
• add is the command used to add a file or directory to the repository.
• ${filename} is a placeholder representing the actual filename or path of the file you want to add. You need to replace ${filename} with the actual filename or path when running the command.

To add a file to the repository, you would replace ${filename} with the name or path of the file you want to add. For example, if you want to add a file called "readme.txt" in the current directory, you would run the command: hg add readme.txt.
