 When you're done testing your reactions, you can either use the built-in Pigment Lab simulator (`Window > Run Simulator`) to experiment with recipes, without dipping into your precious ingredient stocks.  Alternatively, you can export your reactions in PracticalPaint format.
 
+## Generating Recipes
+
+### What do all these settings do?
+
+* _Minimum Ingredients_ is the minimum number of ingredients the generator will use in a recipe. It's best to leave this at 1 so the simple single-ingredient recipes are included (like 10 carrots for 'carrot')
+* _Maximum Ingredients_ limits how many ingredients will be used in a recipe. Ingredients after the 5th will still affect the resulting color, but won't use their reactions.
+* _Silk Ribbon Recipes_ sets the generator up to create recipes for silk ribbons. Ribbons use a base concentration of 50 instead of the 10 that is used for paint.
+* _Maximum Concentration_ is the maximum recipe concentration. Recipes with a concentration above 10 will still produce a single db of paint, but can use larger quantities of ingredients to make smaller color adjustments. Increasing this will increase the time required to search all the possible combinations.
+* _Full Quantity Depth_ is the number of ingredients in the recipe that will use up to the "full quantity" value as the limit for those ingredients over the ingredient's maximum.
+* _Full Quantity_ is the maximum quantity of any ingredient to use up to the Full Quantity Depth. For example, with a Full Quantity of 15 and a Full Quantity Depth of 3, a recipe could use up to 15 of each of the first 3 ingredients. After that it will be limited by the setting for that specific ingredient.
