The 'Configurable Operations Set' section is a little bit outdated.
Update the text.

Configurable Operations Set
---------------------------
-DAMON provides data access monitoring functionality while making the accuracy
-and the overhead controllable. The fundamental access monitorings require
-primitives that dependent on and optimized for the target address space. On
-the other hand, the accuracy and overhead tradeoff mechanism, which is the core
-of DAMON, is in the pure logic space. DAMON separates the two parts in
-different layers and defines its interface to allow various low level
-primitives implementations configurable with the core logic. We call the low
-level primitives implementations monitoring operations.
+For data access monitoring and additional low level work, DAMON needs a set of
+implementations for specific operations that are dependent on and optimized for
+the given target address space. On the other hand, the accuracy and overhead
+tradeoff mechanism, which is the core logic of DAMON, is in the pure logic
+space. DAMON separates the two parts in different layers, namely DAMON
+Operations Set and DAMON Core Logics Layers, respectively. It further defines
+the interface between the layers to allow various operations sets to be
+configured with the core logic.
-Due to this separated design and the configurable interface, users can extend
-DAMON for any address space by configuring the core logics with appropriate
-monitoring operations. If appropriate one is not provided, users can implement
-the operations on their own.
+Due to this design, users can extend DAMON for any address space by configuring
+the core logic to use the appropriate operations set. If any appropriate set
+is unavailable, users can implement one on their own.
For example, physical memory, virtual memory, swap space, those for specific
processes, NUMA nodes, files, and backing memory devices would be supportable.
-Also, if some architectures or devices support special optimized access check
-primitives, those will be easily configurable.
