-This is the source code that generates the web-app  **A Tool for the Selection of a Functional Green Solvent** created by the [Organic Photonics and Electronics Group (OPEG)](http://www.opeg-umu.se/). It can be found online [here](http://www.opeg-umu.se/green-solvent-tool).

-This app has been created using the Python framework [Dash](https://dash.plotly.com/).
-
-### How does it work?
+The app helps the user to identify functional and environmentally green solvents. The likelihood to be functional is based on **Hansen solubility parameters** (HSP), where a shorter distance in Hansen space (_Ra_) corresponds to a more similar solvent. The **greenness** or **composite score** (_G_) is based on the GlaxoSmithKline (GSK) solvent sustainability guide, where a higher G means a greener alternative.

-1. Use the radio buttons on the left panel to either estimate the **HSP coordinates** of your solute from known functional solvent(s) or to manually enter the values. Then click **UPDATE**.
+## How does it work?
+1. In the upper left panel, either _enter your known functional solvent(s)_ to approximate the Hansen solubility parameters (HSP), or directly enter the _HSP of your solute_. Click **Update**.
 
-2. The solute is highlighted in the **3D Hansen space**. Use the mouse to explore neighboring solvents. Click on the solvent or select it from the table to find more information.
+2. The **Solvent Ranking Table** orders the solvents by their distance (Ra) to the solute in the **Hansen space**, i.e. by their similarity in solubility capacity. You can alternatively rank the solvents according to their composite sustainability score (G, a higher value represents a more sustainable alternative), boiling point (bp), viscosity (η), or surface tension (𝜎).
 
-3. The **Selection table** ranks the solvents based on the distance Ra to your solute, and specifies G.
+3. By selecting a solvent from the **Hansen space** or the **Solvent Ranking Table** you can get detailed information regarding its chemical structure, physical properties, and sustainability indicators.
 
-4. Click **QUICK PATH** to view see a quick testing route towards a green and functional solvent.
+4. In the left pane, click **Refinement options** to define the range for G, bp, η, and 𝜎. Click **Update**.
 
-5. Use the **Advanced options** to refine your search. Click **UPDATE** to apply your changes.
+5. Click **Quick path** for a sequential path to greener functional solvents. Starting from your solute, each iteration finds the next nearest solvent with a G higher than the previous.
