Documentation improvement project

SQUAD documentation isn't ideal. We're aware of the fact that some features are not documented and existing documentation is hard to navigate. Recently Google announced Season of Docs programme. We're taking this opportunity to invite technical writers to help us improve our documentation.

The list of identified issues can be found below. The list starts from most urgent ones:

1. User guides

• Project user guide
• Project administrator guide
• API user guide

2. Features missing documentation

• add documentation for xfail test results
• add documentation for regressions
• add documentation for api filters travesing objects

3. Overall architecture documentation

• need some architecture documentation

Addressing any of the above listed tickets will be more than welcome!
