+# Find Where Yarn Is Installing Binaries
+
+When you run a command like:
+
+```bash
+$ yarn global add create-react-app
+```
+
+[Yarn](https://yarnpkg.com/lang/en/) is going to install any needed
+dependencies including any binaries. So, where is Yarn putting these binaries?
+
+Let's ask:
+
+```bash
+$ yarn global bin
+/Users/jbranchaud/.asdf/installs/nodejs/10.15.3/.npm/bin
+```
+
+This is where it is located on my machine. You'll want to run it on your own
+machine because the exact location will depend on the specifics of your
+installation.
+
+See [the docs](https://yarnpkg.com/lang/en/docs/cli/global/) for more details.
