+# Default Username And Password For New Instance
+
+Let's say you've set up a fresh new instance of MySQL. Perhaps in a docker
+container with a MySQL image. When you first connect to the instance, you'll be
+prompted for a username and password.
+
+What is the username and password for a MySQL instance you've just created?
+
+There are defaults. The default username is `root` and the default password is
+left blank.
+
+So, your connection URL will look something like this:
+
+```
+mysql://root@localhost:3306
+```
+
+You can use that on the CLI or plug it in to the connection details panel of
+your favorite SQL client.

+# Execute A Command From The Workspace Root
+
+[`pnpm`](https://pnpm.io/) is designed to work with monorepos. In a monorepo
+project you'll have a root `package.json` (in the top-level directory of the
+repository) as well as individual `package.json` files per app and package. If
+you're working from within the directory of one of your apps and you invoke a
+command, `pnpm` should execute that command for this app. The `pnpm` CLI does
+give you control to execute the command from the workspace root instead if
+you'd like.
+
+A likely setup is that both your root `package.json` and your individual app
+`package.json` files have a `build` command.
+
+Invoking the build command from `apps/my-app`:
+
+```bash
+pnpm build
+```
+
+will run the `my-app` build command, as specified in its `package.json`.
+
+You could instead throw in [the `--workspace-root`
+flag](https://pnpm.io/pnpm-cli#-w---workspace-root).
+
+```bash
+pnpm --workspace-root build
+```
+
+This will ignore whatever subdirectory you are in and invoke the `build`
+command defined in your top-level `package.json` file.
