1. Get technology that requires a techprint, such as jump packs or the implants that require one.
   
2. Build a techprinter (production building) and assign a bill to create techshards from previously mentioned item.
   
3. Repeat steps 1 and 2 to collect enough (usually 100) techshards to unlock the research.
   
4. Select a pawn and have someone apply the techshards (by right-clicking).
   
5. You now have removed the techprint requirement, meaning you have to research it normally like vanilla.

When using the setting to allow techshards to boost research, you will have more options in the bill details to use as ingredients. You follow the same steps as above but it will boost research instead of removing the techprint requirement.

When using the ability to deconstruct buildings, you have a new option on any building that is locked behind a techprint (or, if using the techshard research boost, anything that is not discovered) to turn it into techshards. This does not work on minified buildings (Maybe I'll fix that someday).
