After installation, go to preferences of Poedit via menu File > Preferences and in Editor tab of options select “Automatically compile .mo file on save” to automatically create .mo file during saving .po file.

Turn on auto compilation of mo file

Let’s say you are not happy with text “Nothing Found” words which appear in empty search results page. Select Edit a translation because you are going to edit existing translation.
