In plain language

What you may do

You may copy, change, distribute, and perform the work, commercially included, for any purpose, with no conditions: the author has waived their copyright and related rights to the fullest extent the law allows (sections 2 and 3), and no attribution is required.

Key limits, as the CC0 text states: trademark and patent rights held by the author are not waived, abandoned, or licensed (section 4(a)); the work is offered as is, without representations or warranties of any kind, including title, merchantability, fitness for a particular purpose, non-infringement, or the absence of defects or errors (section 4(b)); the author takes no responsibility for clearing other people's rights that may apply to the work (section 4(c)).

The Apache-licensed AIQT material

You may use, reproduce, change, and redistribute the work, in source or object form, commercially included, under the conditions of section 4 of the licence:

• give every recipient a copy of the licence (4(a));
• make modified files carry prominent notices stating that you changed them (4(b));
• keep all copyright, patent, trademark, and attribution notices from the source form, other than notices that do not pertain to your derivative work (4(c));
• where the work ships a NOTICE file, include a readable copy of its attribution notices in your distribution: in a NOTICE file, in the source or documentation, or in a display where third-party notices normally appear (4(d)).

Key limits: each contributor grants you a patent licence for the work, which ends for you on the date you file patent litigation claiming that the work infringes a patent (section 3); the licence grants no trademark rights beyond reasonable and customary use in describing the work's origin and reproducing the NOTICE file (section 6); the work is provided as is, without warranties or conditions of any kind (section 7), and contributors are not liable for damages arising from its use (section 8).

The licence text governs; this is a summary, not legal advice.
