+### Many hooks: Parallelism
+
+> All, except deprecated hooks: `checkov`, `terraform_docs_replace` and hooks which can't be paralleled this way: `infracost_breakdown`, `terraform_wrapper_module_for_each`.  
+> Also, there's a chance that parallelism have no effect on `terragrunt_fmt` and `terragrunt_validate` hooks
+
+By default, parallelism is set to `number of logical CPUs - 1`.  
+If you'd like to disable parallelism, set it to `1`
+
+```yaml
+- id: terragrunt_validate
+  args:
+    - --hook-config=--parallelism-limit=1
+```
+
+In the same way you can set it to any positive integer.
+
+If you'd like to set parallelism value relative to number of CPU logical cores - provide valid Bash arithmetic expression and use `CPU` as a reference to the number of CPU logical cores
+
+
+```yaml
+- id: terraform_providers_lock
+  args:
+    - --hook-config=--parallelism-limit=CPU*4
