    Development Cheat Sheet
    ==================================
    yarn cmd dev:modules                Creates a symlink to modules bundles (restart server to apply backend changes - refresh for UI)
                                        After this command, type "yarn watch" in each module folder you want to watch for changes
    yarn cmd watch:core                 Recompiles the server on file modification (restart server to apply)
    yarn cmd watch:studio               Recompiles the bundle on file modification (no restart required - refresh page manually)
    yarn cmd watch:admin                Recompiles the bundle on file modification (no restart required - page refresh automatically)
    yarn cmd watch:shared               Recompiles the bundle on file modification (no restart required - refresh page manually)
    yarn cmd build:modules --m m1,m2,m3 Builds modules m1, m2 and m3 only
                                        Here m1 is the module name like nlu
                                        Modules are separated with a comma (,) and no spaces
    yarn cmd build:modules --a m1       Builds all modules that matches *m1*
    yarn cmd lint --baseBranch=dev      Runs the linter on file difference between base and current branch
    yarn cmd lint --staged              Runs the linter on staged files
    yarn cmd lint --fix                 Runs the linter and try to fix rules which are fixable, then stages fixes
