 # ClipStuff
+## Basic Instructions.
+Clone repo into custom_nodes folder.
+Install the requirements.txt file via pip.
+
+Pass CLIP output from Load Checkpoint into SpecialClipLoader node, then use the outputted clip with standard Clip Text Encode.
+
+See example workflow in examples folder.
+
+### Example Photo
+![Example Photo](assets/first_example.png)
+
+## Functions
+
+## Syntax Elements
+
+1. **Embedding**:
+    - Syntax: `embedding:WORD`
+    - Example: `embedding:face_vector`
+    - Represents a named vector embedding(Textual Inversion).
+
+2. **Word**:
+    - Syntax: Any alphanumeric word including characters such as `,`, `_`, and `-`.
+    - Example: `cat, dog_face, id_123`
+    - Represents simple words or identifiers.
+
+3. **Quoted String**:
+    - Syntax: A string enclosed within double or single quotes. You can escape quotes inside the string using a backslash (`\`).
+    - Example: `"Hello World"`, `'It\'s a sunny day'`
+    - Represents string literals.
+
+## Functions
+
+Here are the available functions and their usage:
+
+1. **Sum Function**:
+    - Syntax: `sum(arg1 | arg2 | ... | argN)`
+    - Adds together multiple embeddings.
+    - Example: `sum(embedding:face1 | dog)`
+
+2. **Negation Function**:
+    - Syntax: `neg(arg)`
+    - Negates the output.
+    - Example: `neg(A embedding:happycats outside)`
+
+3. **Normalization Function**:
+    - Syntax: `norm(arg)`
+    - Normalizes the given vector embedding.
+    - Example: `norm(sum(embedding:face1 | embedding:face2))`
+
+4. **Difference Function**:
+    - Syntax: `diff(arg1 | arg2 | ... | argN)`
+    - Computes the difference between multiple vector embeddings.
+    - Example: `diff(embedding:face1 | embedding:face2)`
+
+### Notes on Arguments:
+- Each function takes one or more arguments.
+- An argument (`arg`) can be an embedding, a word, another function, or a quoted string.
+- For functions that accept multiple arguments, they are separated by the `|` symbol.
+
+## Examples
+
+1. Add two embeddings and normalize the result:
+   ```
+   norm(sum(cat | dog | horse | parrot))
+   ```
+
+2. Negate an embedding:
+   ```
+   neg(embedding:body_vector)
+   ```
+
+3. King - Man + Woman = Queen:
+   ```
+   sum(diff(king|man)|woman)
+   ```
+   or
+   ```
+   sum(king|neg(man)|woman)
+   ```
+   ```
