 What is RPython?
 ----------------
 
-- Subset of Python
+- General framework for dynamic languages
+
+- RPython: a subset of Python
 
   * easy to read
 
   * easy to test
 
-- JIT & GC for free
+- RPython toolchain
 
-- General framework for dynamic languages
+  * Translates RPython code to C
+
+  * Just-in-time compiler (JIT) & garbage collector (GC) for free
+
+
+RPython translation stages
+--------------------------
+
+- (R)Python code
+
+- ``import``
+
+  * Python objects (functions, classes, ...)
+
+- Bytecode analysis, type inference
+
+  * Typed control flow graph
+
+- Translator transformations
+
+  * Add GC & **JIT**
+
+- Code generation
+
+  * C code
+
+- ``gcc``
+
+  * Compiled executable
+

+How does the JIT work?
+----------------------
+
+- "Jitcode": very low-level byte code
+
+  * Translates to machine code
+
+- Translation time
+
+  * Add jitcode representation to RPython functions
+
+- Run-time:
+
+  * Detect **hot** loop
+
+  * Trace one code path through the loop
+
+  * Compile (magic!)
+
+    - with guards to ensure correctness
+
+  * Profit!
