No such kernel named calysto_scheme

[kramimus]

I just tried pip installing calysto in my local virtualenv and ipython/jupyter 5 cannot find the kernel:

$ python --version
Python 2.7.10
$ pip freeze | grep -E 'jupyter|ipython|calysto|metakernel'
calysto-scheme==1.2.0
ipython==5.1.0
ipython-genutils==0.1.0
jupyter==1.0.0
jupyter-client==4.3.0
jupyter-console==5.0.0
jupyter-core==4.1.0
metakernel==0.14.0
$ ipython console --kernel calysto_scheme

jupyter console --kernel calysto_scheme gives similar results.

There are two steps as the README.md says:

pip3 install --upgrade calysto-scheme
python3 -m calysto_kernel install

Yep, looks like I totally missed that, sorry!

I am able to load the kernel now, thanks!

No problem! You are not the first :) Perhaps we need to say two steps up front in the doc.
