 ## Example commands
+
 Use the CLion-provided build directories or your own. Typical invocations:
 
 ### Debug
 <pre>cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug \
   -DFUN_DEBUG=ON -DFUN_WITH_RUST=OFF
-cmake --build build --target build
-</pre>
+cmake --build build --target build</pre>

 ### Release
+
 <pre>cmake -S . -B build_release -DCMAKE_BUILD_TYPE=Release \
   -DFUN_DEBUG=OFF -DFUN_WITH_RUST=OFF
-cmake --build build_release --target build
-</pre>

 ### Enabling optional extensions
+
 <pre>cmake -S . -B build_release -DCMAKE_BUILD_TYPE=Release \
   -DFUN_WITH_CPP=ON -DFUN_WITH_RUST=ON -DFUN_WITH_OPENSSL=ON
-cmake --build build_release --target build

 ### Customizing VM limits

-cmake --build build_custom --target fun
-</pre>
+cmake --build build_custom --target fun</pre>
+
 If `FUN_WITH_RUST` is enabled, ensure `cargo` is available in PATH; the build will invoke it and link the produced static library.
 
 If `FUN_WITH_OPENSSL` is enabled, CMake must detect your system OpenSSL (libcrypto).

 ## Running
 - CLI: run the `fun` executable from your build directory.
-- REPL: `fun -i` or just run `fun` without a script, depending on your CLI version (see [../cli/](../cli/)).
-- Examples: see [../examples/](../examples/).

 ## `MAX_FRAMES` (Default: 128)
+
 This constant defines the **maximum depth of the call stack**. 
 
 When a function is called, the VM creates a "frame" to keep track of that function's execution (where it's at in the code and its local variables). If a function calls another function, a new frame is added on top.

 - **Analogy:** Imagine a stack of dinner plates. `MAX_FRAMES` is the maximum height the stack can reach before it becomes unstable or hits the ceiling.
 
 ## `MAX_FRAME_LOCALS` (Default: 64)

 This constant limits the **number of local variables** each individual function can have.
 
 Every time a function is called, it gets its own space for variables that only exist within that function.

 This constant defines the **maximum number of global variables** available to the entire program.
 
 Global variables are accessible from anywhere in your code, unlike local variables which belong to a specific function.

 ## `STACK_SIZE` (Default: 1024)
+
 This constant sets the size of the **operand stack**.
 
 The VM uses this stack for almost everything it does: adding numbers, comparing values, and passing arguments to functions. Most operations take values from the top of the stack, perform a calculation, and push the result back onto the stack.

 - **Analogy:** Imagine a workbench where you put tools and materials you are currently working on. `STACK_SIZE` is the area of that workbench. If it's too small, you can't work on complex projects.
 
 ## `OUTPUT_SIZE` (Default: 1024)
+
 This constant determines the size of the **output buffer**.
 
 When your program uses commands like `PRINT` or `ECHO`, the results are stored in an internal list before they are displayed or processed further.
