+# How to create proper recordings (with Zoom H5)
+
+* Select an Empty folder (Stereo is recommended)
+* Press (Record) and start createing a Note
+* Press (Play) and (Play) again to Speak the whole Note again, if you made a mistake (this will create Markers)
+* Press (Record) to finish the Note
+
+* Once the Topic is done (which is a collection of Notes)
+* Got though the the list of Samples and trim the beginnings way to the last marker (only if markers in the files exist)
+* **Menu** -> **Edit** -> **Trim**
+  * (>>) and (<<) to jump between markers
+  * (Record) to execute Deletion
+
+Now you have a bunch of already cut Recordings, which can be merged to a proper Topic with the `script.sh`
+
+
+# How to create final MP3s
+
+* Create folder for a topic/note-session
+* move all wav files in there
+* cd in that folder
+* run
+  ```shell
+  bash ../script.sh
+  ```
+* Now you have a mp3 with the name of the folder
