 In order to run each benchmark you should `cd` into the appropriate directory you want to run, set the `WRK_TIME_LENGTH` env var (ex: `export WRK_TIME_LENGTH=30s`) and then `sh init.sh`. You are required to have sidecar running, as well as a fully synced archive node.
 
+NOTE: Some benchmarks might have multiple `sh` scripts with different names in order to run specific benchmarks.

 ### Running via Scripts (Root)
 
 Below are flags, and examples on how to run these benchmarks from the root of the repository. See <root>/scripts/README.md for more information.
