In `@CONTRIBUTING.md`:
- Around line 740-745: Correct the broken grammar and ambiguous phrasing in the
troubleshooting paragraph by replacing "application be" with "application can
use" (or "uses"), "This be solved" with "This can be solved", and change "gives
to Docker images" to "allocates to Docker" (or "allocates to containers"); keep
the diagnostic steps but make the remediation explicit: instruct contributors to
increase the memory allocated to Docker/your container engine in their system
Docker settings and restart the containers, and ensure the example commands and
URL remain accurate for verifying memory growth with `docker stats
nest-frontend`.

Confidence score: 4/5
- This PR is safe to merge; the only concerns are documentation clarity and guidance issues, not functional code changes.
- Most notable issue is misleading troubleshooting guidance in
CONTRIBUTING.mdabout exit codes, which could misdirect users diagnosing OOM problems. - Pay close attention to
CONTRIBUTING.md- fix grammar and clarify the exit-code/OOM explanation.

P2: The troubleshooting text has broken grammar — `application be several GB` and `This be solved` are missing words (`can require` and `can be`), making the instructions unclear. Additionally, `out of memory` should be hyphenated as `out-of-memory` when used as an adjective, and `gives to Docker images` is ambiguous (it's the container engine's memory limit, not something "given to images").</violation>
<violation number="2" location="CONTRIBUTING.md:740">
P2: The troubleshooting note misidentifies `exit code 0` as “usually” OOM. Exit code 0 means the process exited successfully; OOM kills typically surface as exit 137/SIGKILL. This guidance is misleading and may send contributors to the wrong fix.</violation>

Since this is your first cubic review, here's how it works:
- cubic automatically reviews your code and comments on bugs and improvements
- Teach cubic by replying to its comments. cubic learns from your replies and gets better over time
- Add one-off context when rerunning by tagging
@cubic-dev-aiwith guidance or docs links (includingllms.txt) - Ask questions if you need clarification on any suggestion

Suggested change
| To resolve: Increase the memory allocated to Docker in your container engine (e.g. Docker Desktop: Settings → Resources → Memory Limit). | |
| To resolve: Increase memory available to Docker in your container engine. For Docker Desktop on Hyper-V, use Settings → Resources → Memory Limit; for Windows with WSL2 backend, configure WSL memory/swap (e.g., `%UserProfile%\\.wslconfig`), then run `wsl --shutdown` and restart Docker Desktop. |
