+# This is a demonstration prototype for CircuitPython "coproc" on esp32s2/s3
+
+Coproc is a new feature in CircuitPython 8 for using the riscv "ultra low power"
+coprocessor on esp32s2 and esp32s3 microcontrollers.
+
+Two difficulties presented themselves to me so far:
+ * Building a program
+ * Accessing program variables from Python without manually transcribing hex addresses
+
+The code here builds towards addressing these problems.
+
+## Building 
+```
+.../esp-idf/install.sh
+. .../esp-idf/export.sh
+make
+```
+
+## Running Minidump
+
+```
+python py/minidump.py
+```
+
+## Using
+In principle, you now use a wrapper around `minielf` to (A) load the Coproc
+binary and (B) to find symbols within the CoprocMemory.
