 consumption approaches the limit, V8 will spend more time on
 garbage collection in an effort to free unused memory.
 
-The `SIZE` parameter can be specified in two formats:
-
-* **Megabytes**: A number representing the heap size in MiB (e.g., `1536`)
-* **Percentage**: A number followed by `%` representing a percentage of available system memory (e.g., `50%`)
-
-When using percentage format, Node.js calculates the heap size based on the available system memory.
-The percentage must be greater than 0 and up to 100.
-
 On a machine with 2 GiB of memory, consider setting this to
 1536 (1.5 GiB) to leave some memory for other uses and avoid swapping.
 
 ```bash
-# Using megabytes
 node --max-old-space-size=1536 index.js
-
-# Using percentage of available memory
-node --max-old-space-size=50% index.js
 ```
