+# JavaScript Action Template
+
+This template offers an easy way to get started writing a javascript action with TypeScript compile time support, unit testing with Jest and using the GitHub Actions Toolkit.
+
+## Getting Started
+
+See the walkthrough located [here](https://github.com/actions/toolkit/blob/master/docs/javascript-action.md).
+
+In addition to walking your through how to create an action, it also provides strategies for versioning, releasing and referencing your actions.

+### Checkin
+
+- Do checkin source (src)
+- Do checkin build output (lib)
+- Do checkin runtime node_modules
+- Do not checkin devDependency node_modules (husky can help see below)
+
+### devDependencies
+
+In order to handle correctly checking in node_modules without devDependencies, we run [Husky](https://github.com/typicode/husky) before each commit.
+This step ensures that formatting and checkin rules are followed and that devDependencies are excluded. To make sure Husky runs correctly, please use the following workflow:
+
+```
+npm install                                 # installs all devDependencies including Husky
+git add abc.ext                             # Add the files you've changed. This should include files in src, lib, and node_modules (see above)
+git commit -m "Informative commit message"  # Commit. This will run Husky
+```
+
+During the commit step, Husky will take care of formatting all files with [Prettier](https://github.com/prettier/prettier) as well as pruning out devDependencies using `npm prune --production`.
+It will also make sure these changes are appropriately included in your commit (no further work is needed)
