 * Make sure you sourced `build/envsetup.sh`. This is especially common and worth suspecting if none of the build commands like `breakfast` and `lunch` work. If you have `repo sync`ed do this again.
 * Make sure you’re at the root of the build tree. Again, to quickly jump there, use `croot`.
 * Make sure you ran `breakfast` correctly and it did not error out. Missing device files will prevent successful builds.
+* Make sure your computer meets minimum requirements to compile AOSP. Chances are, you need more memory/CPU power to complete a build.
 * Make sure your computer itself isn’t faulty. HDDs usually die first, followed by RAM. SSDs rarely die but failure is not unheard of.  In extremely rare cases, your CPU may have a defect. If you're unsure, run a stress test using a program like Prime95.
