 ### 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)
+- Do checkin a single index.js file after running `ncc`
+- Do not checking node_modules
 
-### devDependencies
+### NCC
 
-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:
+In order to avoid uploading `node_modules` to the repository, we use [zeit/ncc](https://github.com/zeit/ncc) to create a single `index.js` file that gets saved in `dist/`.
 
+If you're developing locally you can run
 ```
-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
+npm install
+tsc
+ncc build
 ```
+You can also do
+```
+npm run-script build # runs tsc
+npm run-script format # runs prettier --write
+npm run-script format-check # runs prettier --check
+npm run-script test # runs jest
+npm run-script release # runs ncc build
+```
+
+Any files generated using `tsc` will be added to `lib/*`, however those files also are not uploaded to the repository and are excluded using `.gitignore`.
+
+### Testing
+
+Tests are included under `_tests_/*` and can be run using `npm run-script test`.
 
-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)
+We ask that you include a link to a successful run that utilizes the changes you are working on. For example, if your changes are in the branch `newAwesomeFeature`, then show an example run that uses `setup-python@newAwesomeFeature` or `my-fork@newAwesomeFeature`. This will help speed up testing and help us confirm that there are no breaking changes or bugs.
