-## What should I do when output image is bad
+## Installation
+
+### Using git
+
+From root folder of ComfyUI, goto `./ComfyUI/custom_nodes` and open terminal or command prompt and type following:
+`git clone https://github.com/Filexor/SEGA_Anima.git`
+
+### Via downloading zip
+
+Click green "\<\> Code ▾" button and then click "Download ZIP" and extract folder to `./ComfyUI/custom_nodes` .
+
+### Via ComfyUI Manager
+
+This method is currently unavailable.
+
+## Usage
+
+Insert "SEGA Anima" node to between "Load Diffusion Model" node and "KSampler" node.
+
+### What should I do when output image is bad
 
 1. If image does not appear, first thing you have to do is decreasing "training_resolution". Too low "training_resolution" results structual inaccuracy.
 2. Adjust CFG. Normally, higher CFG is needed for high resolution output.
