Hello.
Being a novice in programming, the use of the Blocky node is a good way to start.
Following the indications of "Store data in Node Red memory · bartbutenaers/node-red-contrib-blockly Wiki · GitHub" I'm trying to create a flow context variable, but, I don't see the following block

Thank you very much for your attention

Thanks you @BartButenaers , that's the solution
@carflomi,
Thanks for remind me about updating the tutorials!
BTW the readme and wiki pages have been rewritten for the Blockly node v2.0.0 release. This release is 99% finished, but I still need to solve 1 issue together with @cymplecy. But meanwhile the wiki will be confusing, since it is about functionality that has not been published yet on NPM...
Wow, that's great news, I'm looking forward to the new version with great anticipation.
I'm going to dare to suggest a possible functionality.
Add the possibility of a section to generate JSON (see as an example (A Blockly-based visual editor for JSON structures.)
Note that you can do something similar already with the existing blocks in our node:

You are welcome!
I have created a new animation demo, and updated the wiki page.
Note that it is created with the blockly node version, so there will be some icons in the demo that you haven't got in your current blockly node yet
