 ### Compiling Red Eclipse
 
-- Open redeclipse.cbp in Code::Blocks as a project.
-- Select the debug build (redeclipse-amd64-dbg)
+In the MSYS2 prompt, change directory to the location that of Red Eclipse:
+```
+cd /c/Users/qreev/Documents/redeclipse
+```
+*(note: that MSYS2 is using "/" as the root directory, so that `C:\Users\qreev\Documents\redeclipse` would be written as `/c/Users/qreev/Documents/redeclipse`*
+
+First you must compile with debug symbols:
+```
+make -Csrc clean && CXXFLAGS=-ggdb3 make -Csrc install
+```

-- Red Eclipse will now start, attempt to crash it.
-- Once crashed, you will see the debugger near the bottom of the screen with a Command input. Write `bt full` in that command input and press enter.
+Now attempt to reproduce the problem in game. Once Red Eclipse has crashed, GDB will catch this and present a prompt. At this prompt run:
+```
+bt full
+```
+This will produce a backtrace, copy and paste this to an accessible place such as a crash report on the Red Eclipse [Github Issues page](https://github.com/redeclipse/base/issues) or paste to the Red Eclipse [Discord](https://discord.com/invite/RPDmG5Z).
