 ## Installation
 
-To run the current development version of iD on your own computer:
-
-#### Cloning the repository
-
-The repository is reasonably large, and it's unlikely that you need the full history (~200 MB). If you are happy to wait for it all to download, run:
-
-```
-git clone https://github.com/openstreetmap/iD.git
-```
-
-To clone only the most recent version, instead use a 'shallow clone':
-
-```
-git clone --depth=1 https://github.com/openstreetmap/iD.git
-```
-
-If you want to add in the full history later on, perhaps to run `git blame` or `git log`, run `git fetch --depth=1000000`
-
-#### Building iD
-
-1. `cd` into the newly cloned project folder
-2. Run `npm install`
-3. Run `npm run all`
-3. Run `npm start`
-4. Open `http://127.0.0.1:8080/` in a web browser
-
-For guidance on building a packaged version, running tests, and contributing to
-development, see [CONTRIBUTING.md](CONTRIBUTING.md).
