+### **1.7 Dev setup (7): Install local codebase spell checker**
+
+You must use VS Code as your local text editor to install the VS Code extension for spell checking your codebase, Code Spell Checker.
+
+The recommended installation method is to install Code Spell Checker directly from the VS Code text editor, and those instructions can be found [here](https://code.visualstudio.com/learn/get-started/extensions). The extension can also be installed via the VS Code Marketplace website [here](https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker). <strong><em>Feel free to reach out in the [Hack for LA Slack channel](https://hackforla.slack.com/messages/hfla-site/) if you have trouble installing the extension in VS Code.</em></strong>
