The first thing you need to do is add the text of your subtitles. You can do this by typing the text directly into the file, or by importing it from a text file or a spreadsheet.

Once you have added the text, you need to specify the timing of the subtitles. This is done by adding tt:start and tt:end tags to the text. The tt:start tag specifies the time at which the subtitle should start to appear, and the tt:end tag specifies the time at which it should disappear.

You can also use tt:style tags to specify the appearance of the subtitles. This can include things like the font, size, color, and position of the text.

Once you have finished creating and editing your TTML file, you can save it and use it with your media player or other software application.
