+## Compiling and pushing changes
+
+Checking in your node_modules directory can cause problems. As an alternative, you can use a tool called @vercel/ncc to compile your code and modules into one file used for distribution.
+
+Install vercel/ncc by running this command in your terminal.
+
+`npm i -g @vercel/ncc`
+
+Compile your index.js file.
+
+`ncc build index.js --license licenses.txt`
+
+You'll see a new dist/index.js file with your code and the compiled modules. You will also see an accompanying dist/licenses.txt file containing all the licenses of the node_modules you are using.
+
+Change the main keyword in your action.yml file to use the new dist/index.js file.
+
+`main: 'dist/index.js'`
+
+If you already checked in your node_modules directory, remove it.
+
+`rm -rf node_modules/*`
+
+From your terminal, commit the updates to your action.yml, dist/index.js, and node_modules files.
+
+```shell
+git add action.yml dist/index.js node_modules/*
+git commit -m "Use vercel/ncc"
+git tag -a -m "My first action release" v1.1
+git push --follow-tags
+```
