+## Custom Resources
+
+ROCmRoll supports per-instance resource overlays in the `custom\` folder at the repository root. Files placed there are loaded after the global manifests and do not require editing any source file.
+
+### Layout
+
+```text
+custom\
+  <instanceName>\
+    requirements.txt      Optional extra pip packages for this instance
+    custom_nodes.json     Optional extra custom nodes for this instance
+```
+
+### Custom requirements
+
+Place a standard `requirements.txt` in `custom\<instanceName>\`:
+
+```text
+custom\rocm-stable\requirements.txt
+```
+
+ROCmRoll installs it after ComfyUI's own `requirements.txt` using the same pip cache and upgrade strategy. A non-zero pip exit code is a fatal error and reports `ROCMROLL-COMFY-005`.
+
+This file is picked up by every code path that runs ComfyUI dependency installation:
+
+- `instance install`
+- `comfyui requirements`
+- `instance update --comfyui`
+- `instance repair --comfyui`
+
+### Custom nodes
+
+Place a `custom_nodes.json` in `custom\<instanceName>\` using the same format as `source\manifests\custom-nodes.json`:
+
+```json
+{
+  "default": [
+    {
+      "name": "MyCustomNode",
+      "repo": "https://github.com/user/MyCustomNode.git",
+      "ref": "main",
+      "installRequirements": true
+    }
+  ]
+}
+```
+
+ROCmRoll clones and configures these nodes after the default manifest nodes. Clone failures are non-fatal warnings. The list is processed by every code path that handles custom nodes:
+
+- `instance install`
+- `comfyui nodes --install` / `--update`
+- `instance repair --custom-nodes`
+
+The `custom\` folder is root-relative and is not user-configurable in `rocmroll.ini`.

+## Custom Resources Overlay
+
+ROCmRoll supports per-instance resource overlays in a `custom\` folder at the repository root. The folder is root-relative and not user-configurable via `rocmroll.ini`, following the same convention as `workspaces\`.
+
+### Layout
+
+```text
+custom\
+  <instanceName>\
+    requirements.txt      Extra pip packages installed after ComfyUI requirements
+    custom_nodes.json     Extra custom nodes installed after the default manifest
+```
+
+### Custom requirements
+
+`Invoke-InstallComfyDeps` (in `RocmRoll.ComfyUI`) checks for `custom\<instanceName>\requirements.txt` after installing ComfyUI's own `requirements.txt` and `manager_requirements.txt`. If the file exists it is installed with `pip install --upgrade-strategy only-if-needed -r <file>` using the shared pip cache. A failed install raises `ROCMROLL-COMFY-005`.
+
+Because the custom requirements block lives inside `Invoke-InstallComfyDeps` it is automatically executed by all call sites: full install, `comfyui requirements`, `instance update --comfyui`, and `instance repair --comfyui`.
+
+### Custom nodes
+
+`Invoke-InstallCustomNodes` (in `RocmRoll.CustomNodes`) checks for `custom\<instanceName>\custom_nodes.json` after processing the global manifest. The file uses the same JSON schema (`{ "default": [ { name, repo, ref, installRequirements } ] }`). Each entry is processed by the shared `Invoke-ProcessNodeEntry` helper that handles clone, update, and requirements installation. Clone failures are non-fatal warnings.
+
+Because the custom nodes block lives inside `Invoke-InstallCustomNodes` it is automatically executed by all call sites: full install, `comfyui nodes --install`, `comfyui nodes --update`, and `instance repair --custom-nodes`.

 ## Install Pipeline
 
 `RocmRoll.Core.Invoke-FullInstall` is the high-level install pipeline. It is idempotent where practical and is protected by an instance lock.
