-### Local Development
-
-This project builds with node version:
-
-<!-- CODEBLOCK_START {"value": ".nvmrc", "hideValue": true} -->
-<!-- prettier-ignore -->
-~~~~~~~~~~bash
-v20.10.0
-~~~~~~~~~~
-
-<!-- CODEBLOCK_END -->
-
-After cloning the repository, install dependencies and build the project:
-
-```
-npm ci
-```
-
-Build the library and watch for changes:
-
-```
-npm start
-```
-
-Link your local copy:
-
-```
-npm link
-```
-
-`markdown-inject` commands in any terminal will now run using your local copy.
-
-### Validation
-
-This app ships with a local suite of [jest](https://jestjs.io/) tests, [eslint](https://eslint.org/) + [prettier](https://prettier.io/) configurations for code consistency and formatting, and [TypeScript](https://www.typescriptlang.org/) type validation. Each of these features can be validated using...
-
-```bash
-npm test
-npm run lint
-npm run build
-```
-
-A `validate` utility script chains these calls together, and is called on every commit.
-
-```bash
-npm run validate
-```
