+# Tiled Sampling Example
+
+Uses blenderneko's [Tiled KSampler node](https://github.com/BlenderNeko/ComfyUI_TiledKSampler)
+
+<!--
+<img src="some image" align="middle">
+-->
+
+## Purpose
+
+This workflow uses tiled sampling to sample large images in hirez fixes. The Tiled KSampler is similar to the Advanced KSampler node, so there's a couple imporant differences from the "standard" KSampler.
+* denoise is handled through start and stop steps compared to total steps.
+* using 30 steps, start at step 15 and end at step 30 (15 steps) is equivalent to 0.500 denoise.
+* Tile Width and Height should be the maximum size the GPU can reasonably handle.
+  * setting these values low can result in extra artiftacts and noise
