 This will build the `qjs` and `qjsc` executables and other test tools. Head over [here](./cli) for
 instructions on how to use them.
 
+## Big Endian architecture support
+
+When compiling for a big endian target the bundled bytecode must be regenerated. The generated bytecode is endian dependent
+and the currently shipped source builds have little endian bytecode. To regenerate it:
+
+```bash
+make codegen
+```
+
+Then proceed with `make` as normal.

 ## Amalgamated builds
 
 The amalgamated build rolls individual source files into a single big file.
