+"""This module is the core of the ggml-python library, it exposes a low-level [ctypes](https://docs.python.org/3/library/ctypes.html)-based interface for ggml.
+
+Structures and functions in the `ggml.ggml` module map directly to the original ggml C library and
+they operate at a fairly low level.
+No additional runtime checks checks are performed nor is memory management handled automatically.
+You've been warned :).
+
+With that in mind here are some useful things to keep in mind
+
+- Functions accept both ctypes types (c_int, c_bool, c_float, etc.) and Python types (int, bool, float, etc.) as parameters.
+- Functions return Python types for simple values (int, bool, float, etc.) and ctypes types for complex values ([ggml_context_p][ggml.ggml_context_p], [ggml_tensor_p][ggml.ggml_tensor_p], etc.).
+- Memory management is the responsibility of the user. The user must call [ggml.ggml_free][] on the context after calling [ggml.ggml_init][].
+
+Example
+
+```python
+import ggml
+import ctypes
+
+# Allocate a new context with 16 MB of memory
+params = ggml.ggml_init_params(mem_size=16 * 1024 * 1024, mem_buffer=None)
+ctx = ggml.ggml_init(params=params)
+
+# Instantiate tensors
+x = ggml.ggml_new_tensor_1d(ctx, ggml.GGML_TYPE_F32, 1)
+a = ggml.ggml_new_tensor_1d(ctx, ggml.GGML_TYPE_F32, 1)
+b = ggml.ggml_new_tensor_1d(ctx, ggml.GGML_TYPE_F32, 1)
+
+# Use ggml operations to build a computational graph
+x2 = ggml.ggml_mul(ctx, x, x)
+f = ggml.ggml_add(ctx, ggml.ggml_mul(ctx, a, x2), b)
+
+gf = ggml.ggml_build_forward(f)
+
+# Set the input values
+ggml.ggml_set_f32(x, 2.0)
+ggml.ggml_set_f32(a, 3.0)
+ggml.ggml_set_f32(b, 4.0)
+
+# Compute the graph
+ggml.ggml_graph_compute_with_ctx(ctx, ctypes.pointer(gf), 1)
+
+# Get the output value
+output = ggml.ggml_get_f32_1d(f, 0)
+assert output == 16.0
+
+# Free the context
+ggml.ggml_free(ctx)
