+# Transient Attachments
+
+The `transient-attachments` feature allows creation of attachments that allow
+render pass operations to stay in tile memory, avoiding VRAM traffic and
+potentially avoiding VRAM allocation for the textures.
+
+Example Usage:
+```
+wgpu::TextureDescriptor desc;
+desc.format = wgpu::TextureFormat::RGBA8Unorm;
+desc.size = {1, 1, 1};
+desc.usage = wgpu::TextureUsage::RenderAttachment | wgpu::TextureUsage::TransientAttachment;
+
+auto transientTexture = device.CreateTexture(&desc);
+
+// Can now create views from the texture to serve as transient attachments, e.g.
+// as color attachments in a render pipeline.
+```
+
+Notes:
+- Only supported usage is wgpu::TextureUsage::RenderAttachment |
+wgpu::TextureUsage::TransientAttachment
+- It is not possible to load from or store to TextureViews that are used as
+transient attachments
