• Kelsos would be happy
• Scenarios are defined

Story Points

[andrevmatos]

Partly done in #288, still needs to improve, so should stay open

[taleldayekh]

This needs to wait until we have a working package of raiden-ts on npm. It will be difficult to work on this if there is no way to try out the examples in the docs to start with.

Hopefully this can be tackled starting the next iteration.

Refinement whiteboard picture

@taleldayekh Could you break this down into actionable issues?

[andrevmatos]

npm package is working and can be used on es5, esNext & TS projects as far as I could test.

Splitting in 2 or 3 issues

[taleldayekh]

I wrote down some suggestions for restructuring/improving the docs in issue #709 which could be used when splitting into new issues.

Dedicated docs issues have been created and some have been already implemented:
