# Installation And Diagnostics
Use this sub-skill when the user needs to install ESPnet, choose extras, verify imports, diagnose optional modules or host tools, or separate CPU readiness from CUDA/distributed readiness.
## Quick use
- Read [install-matrix.md](references/install-matrix.md) and [troubleshooting.md](references/troubleshooting.md); run `scripts/check_espnet_environment.py` for safe diagnostics.
## Boundaries
Route data layouts to `../recipes-and-data/SKILL.md`, training config to `../espnet2-training/SKILL.md`, inference to `../inference-and-model-zoo/SKILL.md`, and maintainer tests to `../development-and-testing/SKILL.md`.
## Safety
Do not run full recipes, model downloads, training jobs, uploads, demo servers, broad CI, or host-mutating installers without explicit user approval. Keep local/private environment details out of public answers.
