+# CPU backend
+
+All CPU related settings contains in one `cpu` object in config file, CPU backend allow specify multiple profiles and allow switch between them without restrictions. Default auto-configuration create reasonable minimum of profiles which cover all supported algorithms.
+
+### Example
+
+Example below demonstrate all primary ideas of flexible profiles configuration:
+
+* `"rx/wow"` Exact match to algorithm `rx/wow`, defined 4 threads without CPU affinity.
+* `"cn"` Default failback profile for all `cn/*` algorithms, defined 2 threads with CPU affinity, another failback profiles is `cn-lite`, `cn-heavy` and `rx`.
+* `"cn-lite"` Default failback profile for all `cn-lite/*` algorithms, defined 2 double threads with CPU affinity.
+* `"custom-profile"` Custom user defined profile.
+* `"*"` Failback profile for all unhandled by other profiles algorithms.
+* `"cn/r"` Exact match, alias to profile `custom-profile`.
+* `"cn/0"` Exact match, disabled algorithm.
