+# Using the Jupiter Notebook Interface
+
+![Screenshot](img/tabs.png)
+
+The Jupyter notebooks are easy to use yet powerful. The interface, for example, allows to:
+
+* Easily navigate the **file system**, to create, upload, download and manage files and directories.
+* Have multiple tabs, that can be arranged and *snapped* to a corner, to a side, bottom or top of the "snapping area".
+* Tabs can be:
+  * One or more **terminal** tabs, to run commands and scripts.
+  * One or more **notebook** tabs, to write and run code, and to create and manage documents.
+  * One or more **text editor** tabs, to write and edit text files. You can directly edit the text (and save it) from the interface.
+  * Built in preview for HTML files (for example, MultiQC reports), tables (csv, tsv, etc.), and images.
+
+The interface consists of four main components:
+
+![Notebook panel](img/tabs2.png)
+
+1. The **menu bar**, where you can access settings (including font size etc.), and manage the notebook.
+2. The side bar will allow you to select the appropriate side tab. 
+3. The **side area**, which is by default set to the **File Browser**. From here you can navigate directories and upload/download files. You can quickly upload a file by dragging it from your computer and dropping it in the file browser.
+    1. Right-clicking to a file will allow you to download it, rename it, or to "open it" with the appropriate application.
+4. The **snapping tabs area**, where you can place all your open tabs, and arrange them as you like.
+
+
+## Common tasks
+
+### Quickly upload some files to the Notebook
+
+1. Use the side bar (File Browser) to navigate to the appropriate location. Remember that your home directory is not a safe place for storage, and that you should use the `shared-team` directory for your data.
+2. If appropriate, create a new sub directory (e.g. right click in the white area of the file browser and select "New Folder", then type a name for it)
+3. On your local computer, open the directory with the files you want to upload.
+4. Drag the files from your local computer and drop them in the file browser of the notebook interface.
+5. If the file size is relevant you will get a warning. For very large uploads, you should consider using the S3 storage instead.
+
+
+### Edit a file and save it
+
+1. Use the side bar (File Browser) to navigate to the appropriate location.
+2. Some files will open in an editor automatically, otherwise right click on the file and select **"Open with" -> "Editor"**.
+3. When you edit the file, a dot (⚫️) will appear in the tab, indicating that the file has been modified.
+4. Use `Ctrl + S` to save the file (or `Cmd + S` on macOS), or click the save button in the editor.
+
+### Live preview of a (supported) file
+
+1. Use the side bar (File Browser) to navigate to the appropriate location.
+2. Right click on the file and select **"Open with" -> "Editor"**.
+3. Now right-click again on the file and select **"Open with" -> "CSV Previe"** (or other supported preview: like Markdown, HTML...).
+4. When you edit and **save** the file with the editor, the preview will update automatically.
+
+💡 You can use a similar arrangement to keep, for example, a script editor on your left and a terminal to run the script on your right. 
+
+### Using the Python notebook with custom libraries
+
+1. Open a terminal tab.
+2. Create a new environment with the requested libraries plus `ipykernel`, using `conda create -n EnvName ... ipykernel`. Suppose you want to create an environment called `dataexplorer` with Pandas, Seaborn, and Matplotlib, you would use `conda create -n dataexplorer pandas seaborn matplotlib ipykernel`.
+3. Open the launcher, and you will see a new icon with the environment name under the Python Icon. Click on it to create a new notebook with the new environment.
+4. From that notebook you will be able to `import pandas as pd`, for example.
