+# Run A Command With Specific Tool Version
+
+Because I'm using `mise` to manage the versions of tools like Node, I can
+execute commands in the context of specific versions. Behind the scenes `mise`
+makes sure I have the necessary tool(s) installed at the desired version(s).
+
+So, [`mise exec` command](https://mise.jdx.dev/cli/exec.html) will default to
+using the latest version of a tool if I haven't been more specific. At the time
+of this writing, for Node, that is v23.
+
+```bash
+$ mise exec node -- node --version
+v23.9.0
+```
+
+To be specific I could specify the major version with `node@23` like so:
+
+```bash
+mise exec node@23 -- npx repomix
+Need to install the following packages:
+repomix@0.2.39
+Ok to proceed? (y) y
+
+...
+```
+
+Or if I wanted to use a different, older version of Node, I could specify that
+as well. We can see it will first install that and then execute the command:
+
+```bash
+$ mise exec node@22 -- npx repomix
