Yes! and if you want to try it right now. You can build it from source!

@kashishkhullar there are few ways how you can test the build from develop branch. I think the easiest one is to clone the repo and install algob in your system (eg, npm install -g) or run algob from the algob repo directly (this is what I'm using):

git clone https://github.com/scale-it/algo-builder.git
cd algo-builder
yarn build
cd <path to my project>
# you can add the line below as a script in your $PATH directory
<path to algo-builder>/packages/algob/node_modules/.bin/algob init mynewproject

Or use a local "dev" project in algob package, this is what we often use for testing.

cd algo-builder/packages/algob
./project-dev-script.sh create

We will prepare a guide for that.
