+# Kestra JavaScript Libs
+
+This project includes the following tools:
+
+- [Prettier](https://prettier.io/): Formatting
+- [Eslint](https://eslint.org/): Linting
+- [Vitest](https://vitest.dev/): Testing
+- [Rollup](https://rollupjs.org/): Bundling
+
+---
+
+### Development
+
+```bash
+# Install dependencies
+$ npm i
+```
+
+---
+
+### Testing
+
+```bash
+# Runs vitest
+$ npm run test
+
+# Runs vitest with GUI
+$ npm run test:ui
+```
+
+You can test this library using npm symlinks before publishing to npm.
+
+This can be done using the following steps:
+
+```bash
+# Create a symlink for this project to global node_modules
+$ npm link
+
+# Lists all global symlinks. You can also use this command to check if your symlink worked.
+$ npm ls -g --depth=0 --link=true
+
+# Navigate to a different project and symlink this project. NOTE: that project must also be using npm as a package manager.
+$ npm link @kestra-io/libs
+
+# Once you are done with testing, you can remove the symlink. NOTE: this will also remove the dependency in package.json so you will need to reinstall the package again.
+$ npm unlink @kestra-io/libs
+
+# Unlink the package globally to remove the symlink
+$ npm unlink --global @kestra-io/libs
+```
