19. Set up a new project
To start using OmegaT, first create a project that will hold all your files, such as your source file, translation memories, glossaries, and eventually your translated file.
In the Project menu, select New... and type a name for your project. Remember where you are creating the project, because you will need to return to it later.

20. Translate the file
OmegaT will present one segment at a time for you to translate. After you have translated each segment, press Ctrl+U to move to the next untranslated segment.
Whenever you want to see what your translation will look like in its final format, press Ctrl+D to generate the translated document, which will be created in the /target/ subfolder of your project folder.

21. Few more things to remember
If a file does not loads into the Editor pane, then it could be that your source file is in a format that doesn't work in OmegaT.
You can create a glossary by pressing Ctrl+Shift+G, or copy existing glossaries to the/glossary/subfolder of your project folder, and OmegaT will automatically look up words in them.
