+# CLAUDE.md - Project Memories
+
+## Project Overview
+- **What**: Bash installer script (`DR_MINT.sh`) for DaVinci Resolve on Linux Mint 22
+- **Repo**: `28allday/DaVinci-Resolve-Linux-Mint`
+- **Owner**: 28allday
+- **License**: As-is (no formal license)
+
+## Architecture
+- Single bash script (`DR_MINT.sh`) — no other source files
+- Script must be run with `sudo`; uses `logname`/`SUDO_USER` to resolve the real user
+- Installs to `/opt/resolve`
+- Expects DaVinci Resolve ZIP in `~/Downloads/`
+
+## Script Flow (DR_MINT.sh)
+1. Installs FUSE libraries (`fuse`, `libfuse2`)
+2. Installs Qt5 libraries (extensive list for UI support)
+3. Finds and extracts DaVinci Resolve ZIP from ~/Downloads/
+4. Runs `.run` installer with FUSE; falls back to `--appimage-extract` if FUSE fails
+5. Resolves library conflicts (moves bundled `libgio`/`libgmodule` to `not_used/`, copies system `libglib-2.0.so.0`)
+6. Cleans up temp extraction directory
+
+## Key Technical Details
+- Uses `set -eo pipefail` for strict error handling
+- `SKIP_PACKAGE_CHECK=1` bypasses Resolve's distro check (it only officially supports CentOS/RHEL)
+- Qt env vars (`QT_QPA_PLATFORM_PLUGIN_PATH`, `QT_PLUGIN_PATH`, `LD_LIBRARY_PATH`) are set for installer GUI
+- Library conflict: Resolve bundles old glib/gio that clash with Mint's newer system versions
+- Does NOT touch bundled `libc++`/`libc++abi` — C++ ABI dependencies would break
+
+## Code Quality
+- Script has been through shellcheck review (PR #1)
+- Fixes applied: pipefail added, privilege check fixed (`id -u` instead of `whoami`), glob safety for `libgio*`/`libgmodule*` patterns
+- Comments are detailed and comprehensive
+
