Things are really simple with POEditor when it comes to gettext localization. Here is how you translate .po files using our localization management platform:
1. Create translation project
Login to your account, create a new translation project and add a language to it.
2. Import gettext .po file
Use the Options Menu in the project page to import your .po file, with translations in the language you created.
3. Start localization
Add your desired languages for translation, invite your contributors to join and start localizing your po files.
You are almost done localizing, you just need to export your .po file using the Export function from Options Menu from the language page and the translation process will be complete.
