To translate INI files with POEditor, you first need to set up your localization project. Here are the steps.
1. Create a localization project
Log in to your POEditor account, click on Add New Project to create a localization project and add a language to it (your software's source language).
2. Import strings from INI file
In the project page, click on Import Terms in the menu on the right side of the page, to upload the strings from your INI file.
Don't forget to choose to Also import translations to... the language you added at step 1.
3. Localize INI file into target languages
When you are done with the localization, you can export your localized languages to your computer by using the Export button in any Language page.
