+##### Fluent Bit Input
+Fluent Bit can collect application logs from >40 different [sources][2]. Common sources include tailing
+log files and other Fluent Bit instances.
+##### CLP Output Plugin
+Output plugin recieves logs from Fluent Bit and parses them into [CLP IR][1]. CLP IR consists of a timestamp, a list of variable values, and the
+log type. IR is then compressed with [Zstd][3] in default mode without dictionaries.
+##### Output
+Compressed IR output is sent to plugin output (currently only AWS S3 is supported). CLP can directly ingest compressed IR output and convert into archives for efficient storage and search.
+
 ### Usage
 Each plugin has its own README to help get started. Currently, we only have a
 [AWS S3 plugin](plugins/out_clp_s3/README.md), but please submit an issue if
