+### How to compile examples?
+
+***NOTE: You have to have RDC installed somewhere.***
+
+If you have rocm (and RDC) installed under `/opt/rocm` - then you can simply do:
+
+```bash
+# same as 'mkdir -p build; cd build; cmake ../; cd ../'
+cmake -B build
+# same as 'cd build; make; cd ../'
+make -C build
+```
+
+If you have rocm installed under a different directory, then you will have to
+add that path with one of the following ways:
+
+- `cmake -DROCM_DIR=/custom/rocm/path -B build`
+- `ROCM_PATH=/custom/rocm/path cmake -B build`
+
+followed by `make -C build`
+
+You can also set ROCM\_PATH environment variable.
+
+
+### I can't find rdc!
+
+- Is RDC installed?
+- Is RDC installed under `/opt/rocm`?
+- Can you find `/opt/rocm/lib/cmake/rdc/rdcTargets.cmake`?
+
+
+### Where is rdc?
+
+```bash
+ldd build/diagnostic
+```
+
+Look for `librdc_bootstrap.so`
+
+
+### `diagnostic` is halted, but other examples work
+
+Did you wait long enough?
+
+It takes a while to run. 46 seconds on my machine with 2 GPUs.
+
+
+### `Couldn't find the platform configure..`
+
+### `Couldn't find the config for the Device...`
+
+That's probably ok. The examples will still run.
+
+Try to `cd` into the config directory and call these examples from there.
