1. Create a snippet (http://create.tinybrain.de) [You will be prompted to create an account if you don't have one yet.]
2. Name, category etc is not important. Leave "Document" as the type.
3. Be sure to tick the "Public" checkbox.
4. In the "Content" area, put in a JSON document like the one in #240.
5. Save the snippet. Remember your ID, e.g. #249.
6. Left-click on the TinyBrain icon (right-bottom corner of your desktop).
7. Type (exactly like this): ['setExtensions', '#249']
8. Hit enter.
9. TinyBrain is now extended as soon as you start a new conversation with it.

* To go back to unextended mode, type instead: ['setExtensions', '']

* To see what extensions are installed, type: !extensions
