+# Invoke Prompt Editor POC
+
+This is a POC (proof-of-concept) front-end for a new prompt editor for [Invoke](https://invoke-ai.github.io/).
+
+This will envtually be merged into the Invoke code base.
+
+## Features and Usage
+
+There are 2 tabs shown:
+
+- **Prompt Composer** This is where you'll add prompt items to your composition.
+- **Text Prompt** This is the original native prompt of Invoke. As you edit in the **PromptComposer**, the
+text will be updated.
+
+![The prompt composer](image-1.png)
+
+### Prompt Library
+
+The prompt library is indicated by the ![library book](image.png) symbol. If you click in, a prompt library will open.
+
+To insert a prompt into the composer, click the **plus icon** (+).
+
+To add a new prompt to the library, use the fields at the bottom.
+
+### Prompt Composer
+
+The prompt composer as bare prompts (called **Nugget**s).
+
+Each **Nugget** has a score, indicated by a number beside the prompt. The number relates to the number of times
+`+` or `-` is added to the prompt
+
+**Nugget**s can be grouped into components called **Operations**. To group **Nugget**s together, ensure you're in *dnd Mode*,
+and move one nugget onto another.
+
+If you want to add a nugget to an *operation*, drag it into the *operation*.
+
+To change the *operator*, right click on the **Operation** and select a new one.
+
+**Limitations:**
+- Operations cannot be grouped into other **Operation**s.
+- **Nugget**s must be grouped by category (e.g. "Vibes" can only be grouped with other "Vibes").
