feature implementations into well-documented pull requests that clearly communicate changes, rationale, and testing to the team. + +## Process + +### Step 1: Analyze Changes +Use git commands to understand what has changed: + +```bash +# Get current branch name +git branch --show-current + +# Get the base branch (usually main or develop) +git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@' + +# See all changed files +git diff --name-only origin/main...HEAD + +# See the full diff +git diff origin/main...HEAD + +# See commit history for this branch +git log origin/main..HEAD --oneline +``` + +### Step 2: Read Pull Request Template +Check if a PR template exists and use it as the structure: + +```bash +# Check for PR template in common locations +ls -la .github/pull_request_template.md +ls -la .github/PULL_REQUEST_TEMPLATE.md +ls -la .github/PULL_REQUEST_TEMPLATE/ +``` + +If no template exists, use the Three Rivers Bank standard format (see below). +
