+# Ntitled
+
+Simple tool for downloading subtitles from opensubtitles. Useful for minimal Upnp setups in combination with TVs.
+
+## How it works
+
+It works by scanning the `BASE_PATH` from the env and displays all files from the directory. Whenever a file is encountered, ntitled will attempt
+to find a file of the same name with a `.srt` extension. Any files that have a matching `.srt` file will be considered checked by ntitled.
+
+To search for subtitles, click on any file. A bullseye means the subtitles match the movie hash as per opensubtitles. To download subtitles, click the download button and the corresponding srt file will be placed in the same directory with the same name as the video file.
