 # ⚡ DedupBench SIMD Builds
 
-To use any of the vector-accelerated CDC algorithms, an alternative Dedupbench build is required. Choose the right SIMD build when running `install.sh` or use the manual commands commands below. We have provided preconfigured files for all algorithms with 8KB chunk sizes for convenience.
