+## Metrics Calculation
+
+Metrics calculation can be elegantly managed during the measure step outlined
+in the `Makefile`. This process initiates with the execution of `steps/measure.sh`,
+which performs several preparatory tasks:
+
+1. Creating the necessary files and directories.
+2. Collecting jobs to execute in parallel,
+   with one job designated for each Java file to analyze metrics.
+3. Running the jobs using `help/parallel.sh`.
+
+For each job, `steps/measure-file.sh` is executed,
+resulting in the following organized file structure:
+
+```text
+dataset/
+  measurements/
+    yegor256/
+      cactoos/
+        Main.java.m
+        Main.java.m.LOC
+        Main.java.m.CC
+        Main.java.m.CoCo
+        ...
+```
+
+In this structure, `{file_name}.m` serves as a buffer
+for intermediate results during calculations.
+The files named `{file_name}.m.{metric_name}` store the calculated metrics,
+where `{metric_name}` corresponds to the specific metric
+for the file `{file_name}`.
