+Certainly! Here’s a concise and highly technical reference guide based on our discussion about handling file deletions and commits in Git:
+
+### 1. **Reviewing Changes**
+Before making any changes to your Git repository, always check the current status to see untracked or modified files.
+
+```bash
+git status
+```
+
+### 2. **Staging Changes**
+To stage changes, including file deletions or modifications:
+
+- **Stage a specific file:**
+  ```bash
+  git add <file_path>
+  ```
+
+- **Stage a deleted file:**
+  ```bash
+  git rm <file_path>
+  ```
+
+- **Stage recursive deletion for directories:**
+  ```bash
+  git rm -r <directory_path>
+  ```
+
+### 3. **Committing Changes**
+After staging the changes, commit them with a clear and descriptive message. The message should concisely explain the what and why of the changes.
+
+```bash
+git commit -m "<commit_message>"
+```
+
+### 4. **Pushing Changes**
+To synchronize your local changes with the remote repository:
+
+```bash
+git push origin <branch_name>
+```
+
+### 5. **Handling Divergent Branches**
+If you encounter a message about divergent branches during a pull, you have several options to reconcile them:
+
+- **Merge (creates a merge commit):**
+  ```bash
+  git pull --rebase=false
+  ```
+
+- **Rebase (reapplies local commits on top of fetched commits):**
+  ```bash
+  git pull --rebase=true
+  ```
+
+- **Fast-forward only (rejects non-fast-forward pulls):**
+  ```bash
+  git pull --ff-only
+  ```
+
+### 6. **Force-Pushing Changes**
+To overwrite remote changes with your local branch (use with caution):
+
+```bash
+git push origin <branch_name> --force
+```
+
+### 7. **Best Practices for Commit Messages**
+- Keep the subject line around 50 characters.
+- Use the body to explain "what" and "why", not "how".
+- Use imperative mood in the subject line.
+
+### 8. **Ignoring Files**
+To prevent tracking of unnecessary files like `.DS_Store`, create a `.gitignore` file:
+
+- **Example `.gitignore` content:**
+  ```
+  .DS_Store
+  ```
+
+### 9. **Git Configuration for Handling Pulls**
+Set a global preference for how pulls are handled across all repositories:
+
+- **For merging:**
+  ```bash
+  git config --global pull.rebase false
+  ```
+
+- **For rebasing:**
+  ```bash
+  git config --global pull.rebase true
+  ```
+
+- **For fast-forward only:**
+  ```bash
+  git config --global pull.ff only
+  ```
+
+This guide consolidates the key actions and commands in Git related to staging, committing, and pushing changes, along with best practices and configuration tips. Use it as a technical reference to manage your projects effectively in Git.
