 ## Usage
 
+### Repository Detection
+
+`fgj` automatically detects the repository from your git context, similar to `gh`:
+
+```bash
+# When inside a git repository, no -R flag needed!
+cd /path/to/your/repo
+fgj pr list              # Automatically uses current repo
+fgj issue list           # Automatically uses current repo
+fgj pr view 123          # Automatically uses current repo
+
+# Or explicitly specify a repository with -R
+fgj pr list -R owner/repo
+```
+
+The tool reads `.git/config` to find the origin remote and extract the owner/repo information. If you're not in a git repository, you'll need to use the `-R` flag.
+
 ### Pull Requests
 
 ```bash
-# List pull requests
+# List pull requests (auto-detects repo from git)
+fgj pr list
+
+# Or specify explicitly
 fgj pr list -R owner/repo
 
+# Filter by state
+fgj pr list --state closed
+
 # View a specific pull request
-fgj pr view 123 -R owner/repo
+fgj pr view 123
 
 # Create a pull request
-fgj pr create -R owner/repo -t "PR Title" -b "PR Description" -H feature-branch -B main
+fgj pr create -t "PR Title" -b "PR Description" -H feature-branch -B main
 
 # Merge a pull request
-fgj pr merge 123 -R owner/repo --merge-method squash
+fgj pr merge 123 --merge-method squash
 ```
 
 ### Issues
 
 ```bash
-# List issues
+# List issues (auto-detects repo from git)
+fgj issue list
+
+# Or specify explicitly
 fgj issue list -R owner/repo
 
+# Filter by state
+fgj issue list --state all
+
 # View an issue
-fgj issue view 456 -R owner/repo
+fgj issue view 456
 
 # Create an issue
-fgj issue create -R owner/repo -t "Issue Title" -b "Issue Description"
+fgj issue create -t "Issue Title" -b "Issue Description"
 
 # Comment on an issue
-fgj issue comment 456 -R owner/repo -b "My comment"
+fgj issue comment 456 -b "My comment"
 
 # Close an issue
