 # How Can I Rewrite My Commit Message?
 You can `git reset --soft upstream/main` and `git commit --forge`, this will merge your changes into one commit.
 
-Or you also can use git rebase. But we will still merge them into one commit when it is merged.

+# Check Code Coverage
+If you are developing on vscode, you can use vscode plugin [Coverage Gutters](https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters)
+
+And also need to install llvm-cov
+```sh
+cargo install cargo-llvm-cov
+
+rustup component add llvm-tools-preview
+```
+
+If you are using goverage gutters plugin, add these config to let it know lcov output.
