+# Link A JavaScript Package Locally
+
+If you are putting together a JavaScript package and you'd like to test it
+out locally before putting it on NPM, use `npm link`.
+
+First, from the directory of the package you are creating run:
+
+```bash
+$ npm link
+```
+
+This will symlink the package to the global node modules directory.
+
+Then, from the base project directory that you want to try importing and
+using the package from, run:
+
+```bash
+$ npm link name-of-package
+```
+
+This will create an additional symlink from the global node modules
+directory to the `node_modules` of this target project.
+
+You'll now have access to the project, try an `import` to get what you need
+and try it out.
