+# Autopatcher Pipeline Specification
+
+This document describes the technical pipeline for the autopatcher system, used to automate the patching, building, and integration process of packages such as `electron-builder`.
+
+---
+
+## Pipeline Steps
+
+### 1. Manual Trigger
+
+A GitHub Actions workflow is manually triggered by a developer to begin the update process.
+
+### 2. Branch Initialization
+
+The workflow checks out a new branch named:
+
+```
+electron-builder-autopatch
+```
+
+### 3. Autopatcher Execution
+
+The following command is executed by the workflow:
+
+```
+pnpm run autopatcher electron-builder
+```
+
+This runs the autopatcher script located at:
+
+```
+muffon/scripts/autopatcher/main.js
+```
+
+### 4. Patch Directory Check
+
+The script verifies whether a patch directory for the target package exists:
+
+```
+muffon/patches/<package>
+```
+
+For example, if the target is `electron-builder`, the following must exist:
+
+```
+muffon/patches/electron-builder
+```
+
+If it does not exist, the autopatcher terminates.
+
+### 5. Package Cloning
+
+If the patch directory exists, the autopatcher retrieves the Git URL for the package from `data.json`, then clones the repository.
+
+### 6. Recursive Patching
+
+Once cloning is complete, the autopatcher applies patches recursively to the cloned repository.
+
+### 7. Build Process
+
+After patching, the GitHub Actions workflow proceeds to build the patched package.
+
+### 8. Patch Folder Integration
+
+A post-build script performs the following:
+
+- Runs `pnpm patch electron-builder` to generate a patch folder.
+- Copies necessary assets from the built output to the patch directory.
+- Executes:
+
+```
+pnpm patch-commit <patch_folder>
+```
+
+### 9. Commit Changes
+
+The workflow commits the changes using the message:
+
+```
+Autopatch electron-builder
+```
+
+It then pushes the commit to the `electron-builder-autopatch` branch.
+
+### 10. Pull Request Creation
+
+Finally, the workflow creates a pull request from the newly pushed branch.
