+# ComfyUI Template String
+
+A simple ComfyUI custom node for string interpolation. Define a template with `{}` placeholders, wire up to 10 string inputs, and the node substitutes them in order. Anything inside the braces — e.g. `{subject}` — is treated as a comment and discarded during substitution, so you can label slots for readability without affecting the output.
+
+## Usage
+
+1. Add the **Template String** node (category: `text`)
+2. Write a template with `{}` placeholders. You can put anything inside the braces (like `{subject}` or `{1}`) as a label — it's ignored during substitution, only the position matters
+3. Wire string outputs from other nodes (Set/Get, primitives, etc.) into `input_1` through `input_10` (all 10 slots are optional)
+4. Placeholders are replaced left-to-right by the connected inputs
+
+### Example
+
+**Template:**
+```
+a {subject} in a {setting}, {lighting} lighting, {quality}
+```
+
+**Inputs:**
+- input_1: `burger`
+- input_2: `dim restaurant`
+- input_3: `cinematic`
+- input_4: `8k`
+
+**Output:**
+```
+a burger in a dim restaurant, cinematic lighting, 8k
+```
+
+The names `subject`, `setting`, `lighting`, and `quality` are just labels — `a {} in a {}, {} lighting, {}` would produce the same result. Unconnected inputs are skipped, and unused placeholders are left as-is.
+
+## Install
+
+Copy or symlink into your ComfyUI custom nodes directory:
+
+```bash
+cd /path/to/ComfyUI/custom_nodes
+git clone https://github.com/YOUR_USERNAME/comfyui-template-string.git
+```
+
+Restart ComfyUI. No pip dependencies required.
