+    This script should be run from the Python console inside QGIS.
+
+    It adds online sources to the QGIS Browser.
+    Each source should contain a list with the folowing items (string type):

+# Create points/lines/shapes
+1. New Geopackage Layer (later make sure to export to geojson)
+
+![qgis-screenshots/Untitled%205.png](./qgis-screenshots/Untitled%205.png?raw=true)
+
+2. Toggle Editing Mode On
+
+![qgis-screenshots/Untitled%206.png](./qgis-screenshots/Untitled%206.png?raw=true)
+
+3. Create your feature
+- Right-click to complete
+- Esc to undo all uncompleted edits
+- Vertex Tool/Edit panel can be used to adjust position
+
+![qgis-screenshots/Untitled%207.png](./qgis-screenshots/Untitled%207.png?raw=true)
+
+4. Toggle Editing Mode Off and Save
+5. See what you have created using the Identify Features Tool
+
+![qgis-screenshots/Untitled%208.png](./qgis-screenshots/Untitled%208.png?raw=true)
+
+# Make changes to the attribute table
+1. Open the attribute table
+
+![qgis-screenshots/Untitled%209.png](./qgis-screenshots/Untitled%209.png?raw=true)
+
+2. Toggle Editing Mode On
+
+![qgis-screenshots/Untitled%2010.png](./qgis-screenshots/Untitled%2010.png?raw=true)
+
+3. From here you can do a number of things such as...
+- Create a new field
+
+![qgis-screenshots/Untitled%2011.png](./qgis-screenshots/Untitled%2011.png?raw=true)
+
+- Access the Field Calculator (quickly assign/replace/edit values aka attribute table operations)
+
+![qgis-screenshots/Untitled%2012.png](./qgis-screenshots/Untitled%2012.png?raw=true)
+
+- Select Features (attribute fields) by expressions
+
+![qgis-screenshots/Untitled%2013.png](./qgis-screenshots/Untitled%2013.png?raw=true)
+
+# Import a raster
+- Layer>Add Layer>Add Raster Layer
+- OR just drag and drop
+
+# Clip (or crop) a raster
+Raster>Extraction>Clip Raster by Extent
+
+# Export layer as GeoJSON
+1. Right click the layer you wish to export 
+2. Select Export>Save Features As...
