 # Consistent sampling
 
-This component adds various Sampler implementations for consistent sampling as defined by
+There are two major components included here.
+
+## Original proposal implementation
+
+The original specification for consistent probability sampling is defined by
 <https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/tracestate-probability-sampling.md>
 and <https://github.com/open-telemetry/opentelemetry-specification/pull/2047>.
+It supports sampling probabilities that are power of 2 (1, 1/2, 1/4, ...), and uses 8-bit `r-value` and 8-bit `p-value` in tracestate.
+
+The implementation of this proposal is contained by the package `io/opentelemetry/contrib/sampler/consistent` in this repository and provides various Sampler implementations.

+## Current proposal implementation
+
+The current version of the specification for consistent probability sampling is described by
+<https://github.com/open-telemetry/oteps/blob/main/text/trace/0235-sampling-threshold-in-trace-state.md>.
+It uses **56** bits for representing _rejection threshold_, which corresponds to a much wider range of sampling probabilities than the original proposal.
+
+The implementation of the current proposal is contained by the package `io/opentelemetry/contrib/sampler/consistent56` in this repository and provides implementation for a number of different Samplers.

+* **ConsistentRuleBasedSampler**
+  a sampler that performs stratified sampling by evaluating qualifying conditions and propagating the sampling decision from one of its delegate samplers
