Next steps
----------
1. Start SurrealDB before indexing:
     surreal start --log trace file://\$HOME/.codegraph/surreal.db
2. Create a .env file per repository:
     CODEGRAPH_SURREALDB_URL=ws://localhost:3004
     CODEGRAPH_SURREALDB_NAMESPACE=ouroboros
     CODEGRAPH_SURREALDB_DATABASE=codegraph
     CODEGRAPH_EMBEDDING_PROVIDER=ollama
     CODEGRAPH_LLM_PROVIDER=ollama
3. Warm up your project:
     codegraph index . --force
4. Launch the MCP server:
     codegraph start stdio          # Claude Desktop
     codegraph start http --port 3000

Add ${INSTALL_DIR} to your PATH (e.g. export PATH="${INSTALL_DIR}:\$PATH") if it is not already available.
