-The best way to try out Clutter on your own is to run 2 instances of Clutter and your own Bootstrap server.  So download the latest release from [Clutter Release](https://github.com/Holochain/clutter/releases), unzip it and make 2 copies of the contents into folders called clutter1 and clutter2.  Both folders will have a dna folder and a ui folder in each.

+```
+git clone https://github.com/Holochain/clutter.git
+cd ui-src
+npm install # (or yarn install)
+npm run build # (or yarn build)
+cd ..
+```
+Now if you want to run the app, you can run:
+```
+hcdev web # if you want to just run it temporarily and test it out, with scratch data
+```
+or
+```
+hcd web # if you want to really start to use the app
