-## 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"
- }
- ...
-```
-
-This can be run with `npm run compile`. `npm` knows how to reach into the node_modules directly, so it's not necessary to specify that.
