Cas9-triggered homologous recombination is a fast and inexpensive way to make essentially any desired change to the genome of C. elegans.   

We described this technique in detail in two publications (Dickinson et al. Nature Methods 2013; Dickinson et al. Genetics 2015). We have created this web site as a genome engineering resource for the C. elegans research community. We'll keep it up to date with new protocols, reagent information and answers to questions. 
Best of luck with your experiments!
