+Squiggle is a **monorepo** with four **packages**. 
-
 - **components** is where we improve reactive interfacing with Squiggle

 - **website** is the site `squiggle-language.com`
 
 # Deployment ops
 
-We use Vercel, and it should only concern Slava, Sam, and Ozzie.
+We use netlify, and it should only concern Quinn, Sam, and Ozzie. 
 
 # Development environment, building, testing, dev server
 
 You need `yarn`. 
 
-Being a monorepo, where packages are connected by dependency, it's important to follow `README.md`s closely. Each package has it's own `README.md`, which is where the bulk of information is.
+TODO: fill this out based on all the different packages scripts once they cool down. 
-
-We aspire for `ci.yaml` and `README.md`s to be in one-to-one correspondence.
-
-## If you're on NixOS
-
-You can't run `yarn` outside of a FHS shell. Additionally, you need to `patchelf` some things. A script does everything for you.
-
-```sh
-./nixos.sh
-```
-
-Reasons for this are comments in the script. Then, you should be able to do all the package-level `yarn run` commands/scripts.
-
-# Try not to push directly to develop
-
-If you absolutely must, please prefix your commit message with `hotfix: `.
 
 # Pull request protocol
 
-Please work against `develop` branch. **Do not** work against `master`.
+Please work against `staging` branch. **Do not** work against `master`. Please do not merge without approval from some subset of Quinn, Sam, and Ozzie; they will be auto-pinged. 
 
-- For rescript code: Slava and Ozzie are reviewers
-- For js or typescript code: Sam and Ozzie are reviewers
-- For ops code (i.e. yaml, package.json): Slava and Sam are reviewers
-
-Autopings are set up: if you are not autopinged, you are welcome to comment, but please do not use the formal review feature, send approvals, rejections, or merges.
-
-# Code Quality
-
-- Aim for at least 8/10\* quality in `/packages/squiggle-lang`, and 7/10 quality in `/packages/components`.
-- If you submit a PR that is under a 7, for some reason, describe the reasoning for this in the PR.
-
-* This quality score is subjective.
-
-# Rescript Style
-
-**Use `->` instead of `|>`**  
-Note: Our codebase used to use `|>`, so there's a lot of that in the system. We'll gradually change it.
-
-**Use `x -> y -> z` instead of `let foo = y(x); let bar = z(foo)`**
-
-**Don't use anonymous functions with over three lines**  
-Bad:
-
-```rescript
-  foo
-  -> E.O.fmap(r => {
-    let a = 34;
-    let b = 35;
-    let c = 48;
-    r + a + b + c
-  }
-```
-
-Good:
-
-```rescript
-  let addingFn = (r => {
-    let a = 34;
-    let b = 35;
-    let c = 48;
-    r + a + b + c
-  }
-  foo -> addingFn
-```
-
-**Write out types for everything, even if there's an interface file**  
-We'll try this for one month (ending May 5, 2022), then revisit.
-
-**Use the Rescript optional default syntax**  
-Rescript is clever about function inputs. There's custom syntax for default and optional arguments. In the cases where this applies, use it.
-
-From https://rescript-lang.org/docs/manual/latest/function:
-
-```rescript
-// radius can be omitted
-let drawCircle = (~color, ~radius=?, ()) => {
-  setColor(color)
-  switch radius {
-  | None => startAt(1, 1)
-  | Some(r_) => startAt(r_, r_)
-  }
-}
-```
-
-**Use named arguments**  
-If a function is called externally (in a different file), and has either:
-
-1. Two arguments of the same type
-2. Three paramaters or more.
-
-**Module naming: Use x_y as module names**  
-For example: `Myname_Myproject_Add.res`. Rescript/Ocaml both require files to have unique names, so long names are needed to keep different parts separate from each other.
-
-See [this page](https://dev.to/yawaramin/a-modular-ocaml-project-structure-1ikd) for more information. (Though note that they use two underscores, and we do one. We might refactor that later.
-
-**Module naming: Don't rename modules**
-We have some of this in the Reducer code, but generally discourage it.
-
-**Use interface files (.resi) for files with very public interfaces**

 the packages can be found in `packages`.

+
+The playground depends on the components library which then depends on the language. This means that if you wish to work on the components library, you will need to build (no need to bundle) the language, and as of this writing playground doesn't really work.
 
 # Develop

+For any project in the repo, begin by running `yarn` in the top level (TODO: is this true?) 
 
-```sh
+``` sh

-Then use `turbo` to build the specific packages or the entire monorepo:
+See `packages/*/README.md` to work with whatever project you're interested in. 
 
-```sh
+## `codium` for `rescript` 
-turbo run build
+
+If you have `nix` installed with `flakes` enabled, you can build a `codium` in this repo for `rescript` development, if you don't want to pollute your machine's global editor with another mode/extension. 
+
+``` sh
+nix develop
+codium 
 ```
 
-Or:
+The `nix develop` shell also provides `yarn`.

-
-You can also run specific npm scripts for the package you're working on. See `packages/*/README.md` for the details.

-## Squiggle CLI
-
-This package can be used to incorporate a very simple `import` system into Squiggle.
-
-To use, write special files with a `.squiggleU` file type. In these files, you can write lines like,
-
-```
-@import(models/gdp_over_time.squiggle, gdpOverTime)
-gdpOverTime(2.5)
-```
-
-The imports will be replaced with the contents of the file in `models/gdp_over_time.squiggle` upon compilation. The `.squiggleU` file will be converted into a `.squiggle` file with the `import` statement having this replacement.
-
-## Running
-
-### `npx squiggle-cli-experimental compile`
-
-Runs compilation in the current directory and all of its subdirectories.
-
-### `npx squiggle-cli-experimental watch`
-
-Watches `.squiggleU` files in the current directory (and subdirectories) and rebuilds them when they are saved. Note that this will _not_ rebuild files when their dependencies are changed, just when they are changed directly.
-
-## Further instructions
-
-The above requires having node, npm and npx. To install the first two, see [here](https://nodejs.org/en/), to install npx, run:
-
-```
-npm install -g npx
-```
-
-Alternatively, you can run the following without the need for npx:
-
-```
-npm install squiggle-cli-experimental
-node node_modules/squiggle-cli-experimental/index.js compile
-```
-
-or you can add a script to your `package.json`, like:
-
-```
- ...
- scripts: {
-  "compile": "squiggle-cli-experimental compile"
- }
- ...
-```
-

-[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://github.com/quantified-uncertainty/squiggle/blob/develop/LICENSE)

-# Squiggle components
-
-This package contains the react components for squiggle. These can be used either as a library or hosted as a [storybook](https://storybook.js.org/).
-
-The `@quri/squiggle-components` package offers several components and utilities for people who want to embed Squiggle components into websites.
-
-# Usage in a `react` project
-
-For example, in a fresh `create-react-app` project
-
-```sh
-yarn add @quri/squiggle-components
-```
-
-Add to `App.js`:
-
-```jsx
-import { SquiggleEditor } from "@quri/squiggle-components";
-<SquiggleEditor
-  defaultCode="x = beta($alpha, 10); x + $shift"
-  jsImports={{ alpha: 3, shift: 20 }}
-/>;
-```
-
-# Usage in a Nextjs project
-
-For now, `squiggle-components` requires the `window` property, so using the package in nextjs requires dynamic loading:
-
-```
-
-import React from "react";
-import { SquiggleChart } from "@quri/squiggle-components";
-
-import dynamic from "next/dynamic";
-
-const SquiggleChart = dynamic(
-  () => import("@quri/squiggle-components").then((mod) => mod.SquiggleChart),
-  {
-    loading: () => <p>Loading...</p>,
-    ssr: false,
-  }
-);
-
-export function DynamicSquiggleChart({ squiggleString }) {
-  if (squiggleString == "") {
-    return null;
-  } else {
-    return (
-        <SquiggleChart
-          defaultCode={squiggleString}
-          width={445}
-          height={200}
-          showSummary={true}
-        />
-    );
-  }
-}

-# Build storybook for development
 
+# Build for development
 We assume that you had run `yarn` at monorepo level, installing dependencies. 
 
 You need to _prepare_ by building and bundling `squiggle-lang` 
-
+``` sh
-```sh
 cd ../squiggle-lang
 yarn build
 ```
-
 If you've otherwise done this recently you can skip those.
 
 Run a development server
 
-```sh
+``` sh
 yarn start
 ```
+
+And build artefacts for production,
+
+``` sh
+yarn bundle  # builds components library
+yarn build  # builds storybook app
+```
