-## Memory issues during compilation
+## Limiting the maximum rank of generated procedures
 
-Some issues can be encountered during compilation on low RAM computers.
-These issues are due to the high number of procedures generated by the preprocessor.
-They can be avoided by limiting the maximum rank of generated procedures, as follows with `CMake`:
+Stdlib's preprocessor (fypp) by default generates specific procedures for arrays of all ranks, up to rank 15.
+This can result in long compilation times and, on some computers, exceeding available memory.
+If you know that you won't need all 15 ranks, you can specify the maximum rank for which the specific procedures will be generated.
+For example, with CMake:
 
 ```sh
 cmake -B build -DCMAKE_MAXIMUM_RANK=4
-
 cmake --build build
-
-cmake --build build --target test
+cmake --build build --target test
 ```
 or as follows with `make`:
 
 ```sh
 make -f Makefile.manual FYPPFLAGS=-DMAXRANK=4
 ```
+Note that currently the minimum value for maximum rank is 4.
