-## Development
-
-Pull requests are encouraged and always welcome. [Pick an issue](https://github.com/sveltejs/sapper/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc) and help us out!
-
-To install and work on Sapper locally:
-
-```bash
-git clone git@github.com:sveltejs/sapper.git
-cd sapper
-npm install
-npm run dev
-```
-
-### Linking to a Live Project
-
-You can make changes locally to Sapper and test it against a local Sapper project. For a quick project that takes almost no setup, use the default [sapper-template](https://github.com/sveltejs/sapper-template) project. Instruction on setup are found in that project repository.
-
-To link Sapper to your project, from the root of your local Sapper git checkout:
-
-```bash
-cd sapper
-npm link
-```
-
-Then, to link from `sapper-template` (or any other given project):
-
-```bash
-cd sapper-template
-npm link sapper
-```
-
-You should be good to test changes locally.
-
-### Running Tests
-
-```bash
-npm run test
-```
