 The notes in this notebook give an overview of what Joplin can do and how to use it. In general, the three applications share roughly the same functionalities; any differences will be clearly indicated.

 - **Sidebar** contains the list of your notebooks and tags, as well as the synchronisation status.
 - **Note List** contains the current list of notes - either the notes in the currently selected notebook, the notes in the currently selected tag, or search results.
-- **Note Editor** is the place where you write your notes. There is a **WYSIWYG editor** and a **Markdown editor** - click on **Code View** to switch between both! You may also use an [external editor](https://joplinapp.org/#external-text-editor) to edit notes. For example you can use something like Typora as an external editor and it will display the note as well as any embedded images.

 Joplin was designed as a replacement for Evernote and so can import complete Evernote notebooks, as well as notes, tags, images, attached files and note metadata (such as author, geo-location, etc.) via ENEX files.
 
-To import Evernote data, first export your Evernote notebooks to ENEX files as described [here](https://help.evernote.com/hc/en-us/articles/209005557-How-to-back-up-export-and-restore-import-notes-and-notebooks). Then, on **desktop**, do the following: Open File > Import > ENEX and select your file. The notes will be imported into a new separate notebook. If needed they can then be moved to a different notebook, or the notebook can be renamed, etc. Read [more about Evernote import](https://joplinapp.org/#importing-from-evernote).
