+# Git History Rewrite for Open-Sourcing
+
+This directory contains scripts to rewrite git history for open-sourcing the h2 repository.
+
+## What It Does
+
+The rewrite process performs the following transformations on **all commits** in the repository history:
+
+1. **Adds BSD-3-Clause-Clear copyright headers** to all source files (.c, .h, .S, .py, .sh, .pl, etc.)
+2. **Normalizes email addresses** to @qti.qualcomm.com
+3. **Removes internal references** from commit messages (github.qualcomm.com, Q6Auto, JIRA)
+4. **Adds Signed-off-by lines** to all commit messages
+5. **Sets committer = author** for all commits
+
+## Files
+
+- **rewrite-history.sh** - Master script that orchestrates the entire rewrite
+- **add-copyright-file-callback.py** - Adds copyright headers to source files
+- **email-fixes.py** - Normalizes email addresses
+- **commit-callback.py** - Fixes author/committer names and adds Signed-off-by
+- **sanitize-commit-messages.py** - Removes internal references from commit messages
+- **git-filter-repo** - The git-filter-repo tool
+
+## Usage
+
+### For a Single Branch
+
+```bash
+# 1. Clone the repository (or checkout the branch you want to rewrite)
+git clone <repo-url> h2-rewrite
+cd h2-rewrite
+
+# 2. Copy all the rewrite scripts to the repository root
+cp /path/to/scripts/* .
+
+# 3. Run the rewrite script
+./rewrite-history.sh
+
+# Or skip confirmation prompt:
+./rewrite-history.sh --force
+```
+
+### For Multiple Branches
+
+To rewrite multiple branches, you need to run the script on each branch separately:
+
+```bash
+# Method 1: Rewrite each branch in a separate clone
+for branch in work develop feature-x; do
+    echo "Processing branch: $branch"
+    git clone <repo-url> h2-$branch
+    cd h2-$branch
+    git checkout $branch
+    cp /path/to/scripts/* .
+    ./rewrite-history.sh --force
+    cd ..
+done
+
+# Method 2: Rewrite all branches in one go (advanced)
+# This rewrites ALL branches at once since git-filter-repo processes all refs
+git clone <repo-url> h2-all-branches
+cd h2-all-branches
+cp /path/to/scripts/* .
+./rewrite-history.sh --force
+# All branches will be rewritten
+```
+
+## Important Notes
+
+### Before Running
+
+1. **Make a backup!** This operation rewrites git history and cannot be easily undone
+2. **Use a fresh clone** - Don't run this on your working repository
+3. **Ensure all required files are present** - The script will check for this
+
+### After Running
+
+1. The `origin` remote will be removed (this is normal for git-filter-repo)
+2. You'll need to add a new remote and force-push:
+   ```bash
+   git remote add new-origin <new-repo-url>
+   git push new-origin --all --force
+   git push new-origin --tags --force
+   ```
+
+### Expected Results
+
+- **Commit count**: May be slightly less than original (4-5 commits typically lost due to phantom references)
+- **Copyright headers**: Present in all source files throughout entire history
+- **Internal references**: Completely removed from commit messages
+- **Email addresses**: All normalized to @qti.qualcomm.com
+
+## Validation
+
+The script automatically validates the rewrite and reports:
+- ✓ Copyright headers present
+- ✓ No internal references found
+- ✓ Number of unique committers
+
+You can also manually check:
+
+```bash
+# Check copyright in a file
+git show HEAD:path/to/file.c | head -10
+
+# Check for internal references
+git log --all --format='%s' | grep -i 'github.qualcomm.com'
+
+# List all committers
+git log --all --format='%cn <%ce>' | sort -u
+```
+
+## Troubleshooting
+
+### "Not in a git repository"
+Make sure you're in the root of a git repository.
+
+### "Required file not found"
+Ensure all script files are in the current directory.
+
+### "origin remote removed"
+This is expected. Add a new remote to push to the new repository.
+
+### Commit count decreased
+This is normal. A few commits (typically 4-5) are filtered out because they are phantom references to non-existent commits in merge messages.
+
+## Technical Details
+
+The rewrite uses `git-filter-repo` with multiple callbacks:
+
+1. **file-info-callback**: Modifies file contents to add copyright headers
+2. **email-callback**: Normalizes email addresses
+3. **commit-callback**: Fixes names and adds Signed-off-by
+4. **message-callback**: Sanitizes commit messages
+
+Each callback is applied to every commit in the repository history, ensuring consistent transformations throughout.
+
+## Copyright
+
+All scripts include the BSD-3-Clause-Clear copyright header that will be added to source files.
