+### Turborepo docs
+
+You can checkout how Turborepo works using the built in [README-turborepo.md](README-turborepo.md)
+
+## Getting Started
+
+Install NodeJS. Preferably v18 using nvm or n.
+
+Inside the llamascript directory:
+
+```
+npm i -g pnpm ts-node
+pnpm install
+```
+
+Note: we use pnpm in this repo, which has a lot of the same functionality and CLI options as npm but it does do some things better in a monorepo, like centralizing dependencies and caching.
+
+PNPM's has documentation on its [workspace feature](https://pnpm.io/workspaces) and Turborepo had some [useful documentation also](https://turbo.build/repo/docs/core-concepts/monorepos/running-tasks).
+
+### Test cases
+
+To run them, run
+
+```
+pnpm run test
+```
+
+To write new test cases write them in packages/core/src/tests
+
+We use Jest https://jestjs.io/ to write our test cases. Jest comes with a bunch of built in assertions using the expect function: https://jestjs.io/docs/expect
+
+### Demo applications
+
+You can create new demo applications in the apps folder. Just run pnpm init in the folder after you create it to create its own package.json
+
+### Installing packages
+
+To install packages for a specific package or demo application, run
+
+```
+pnpm add [NPM Package] --filter [package or application i.e. core or simple]
+```
+
+To install packages for every package or application run
+
+```
+pnpm add -w [NPM Package]
+```
