## Branch Structure

## Quick Start
186
+
187
+
```bash
188
+
# Create a new project
189
+
unpac project create myapp
190
+
191
+
# Add packages (must be on a project branch)
192
+
unpac add opam eio
193

unpac add opam lwt --with-deps
194
+
195
+
# Check status
196
+
unpac vendor status

+
```
198
+
199
+
## Commands
200
+
201
+
```bash
202
+
unpac init # Initialize repository
203
+
unpac project create <name> # Create new project
204
+
unpac project switch <name> # Switch to project
205
+
unpac add opam <pkg> # Add package from opam
206
+
unpac vendor status # Show vendored packages

### To resolve manually:
139

1. Edit the conflicting files to resolve conflicts (look for <<<<<<< markers)

2. Stage resolved files: git add <resolved-files>
141

3. Continue the operation: unpac vendor continue

### To abort:
144
+
Run: unpac vendor abort

### Or ask Claude to help:
147
+
```
148

150
+
The conflicting files are:

the vendor branch (upstream code with path prefix vendor/%s/) and

my project branch modifications.
