 This is a fundamental design principle in this library.
-The JSON input must be in memory and must be mutable (ie not readonly) to allow zero-copy and zero-allocation, which is *the* strength of this library.

 Let's see an example to understand why this is important:

+### Why does my device crash or reboot?

+99.999% of the time, this is caused by a "stack overflow", i.e. you have too many variables in the "stack".
+The solution is to move variables to the "heap".
+
+First, replace the `StaticJsonBuffer` by a `DynamicJsonBuffer`.
+Then, use dynamic allocation for the JSON input.
+
+For instance, if you have a program like this:
+
+```c++
+char content[MAX_CONTENT_SIZE];
+StaticJsonBuffer<JSON_BUFFER_SIZE> jsonBuffer;
+
+receive(content);
+JsonObject& root = jsonBuffer.parseObject(content);
+
+Serial.println(root["name"].asString());
+```
+
+you should transform it like that:
+
+```c++
+char* content = malloc(MAX_CONTENT_SIZE);
+DynamicJsonBuffer jsonBuffer(JSON_BUFFER_SIZE);
+
+receive(content);
+JsonObject& root = jsonBuffer.parseObject(content);
+
+Serial.println(root["name"].asString());
+
+free(content);
+```
+
+Of course, this is only possible if your target has enough memory.
+Sometimes, it's just impossible because the MCU is too small.

 ### Parsing succeeds but I can't read the values!
 
 99.999% of the time, this is caused by a confusion between arrays and objects.
