In plain language

What you may do

You may reproduce and share the material, in whole or in part, and produce, reproduce, and share adapted material, commercially included (section 2(a)(1)), in any media and format, with the technical modifications needed to do so (2(a)(4)), under the conditions of section 3:

• attribution (3(a)(1)(A)): keep, where the licensor supplied them, the identification of the creator and anyone else designated for attribution, the copyright notice, the notice that refers to this licence, the notice that refers to the disclaimer of warranties, and a link to the material where reasonably practicable;
• indicate if you modified the material, and keep any indication of previous modifications (3(a)(1)(B));
• indicate that the material is licensed under CC BY-SA 4.0 and include the licence text or a link to it (3(a)(1)(C)); you may meet these conditions in any reasonable manner for the medium, for example by a link to a page that carries the information (3(a)(2)), and you must remove attribution information if the licensor asks, to the extent reasonably practicable (3(a)(3));
• ShareAlike (3(b)): adapted material you share must carry the same licence, this version or later, or a BY-SA compatible licence (3(b)(1)), with that licence’s text or link included (3(b)(2)), and you may not add terms or technological measures that restrict the rights the adapter’s licence grants (3(b)(3)); the same bar on added restrictions applies to the material itself (2(a)(5)(C)).

Where the material includes a database, the licence also covers extracting, reusing, reproducing, and sharing all or a substantial portion of its contents, under the same conditions (section 4).

Key limits:

• no endorsement may be implied (2(a)(6));
• moral rights, such as the right of integrity, and publicity and privacy rights are not licensed, though the licensor waives them to the limited extent needed for you to exercise the licensed rights (2(b)(1));
• patent and trademark rights are not licensed (2(b)(2));
• the licensor waives any right to collect royalties for the licensed uses where possible, and reserves it otherwise (2(b)(3));
• the material is offered as is, without warranties of any kind (section 5(a)), and the licensor is not liable for losses arising from its use (5(b));
• your rights end automatically if you fail to comply (6(a)), and reinstate automatically if you cure the violation within 30 days of discovering it, or on the licensor’s express reinstatement (6(b)).

The suggested attribution in the licence file is: Clean Language by Jeff Posluns, https://cleanlanguage.ai, licensed under CC BY-SA 4.0 (add “Changes were made.” if you modified it).

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 template’s fonts and marks

The template files carry no conditions under CC0 1.0. The fonts may be used, bundled, and redistributed with the template, and their licence files travel with them; the SIL Open Font License does not permit selling the fonts by themselves. The GitHub, LinkedIn, and ORCID marks are not part of the CC0 grant and may be used only as their owners’ terms allow.

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