-### Test Caching
-BitGoJS uses Lerna + Nx for local test caching to speed up development:
-
-```bash
-# Tests are automatically cached when you run them
-yarn unit-test
-
-# Cache status is shown in output:
-# - Fresh run: Tests execute normally
-# - Cache hit: "[existing outputs match the cache, left as is]"
-
-# Clear cache if needed
-yarn clean-cache
-
-# Cache works with all test commands
-yarn unit-test --scope @bitgo/sdk-core  # Caches per package
-yarn unit-test-changed                   # Caches changed packages
-```
-
-The cache automatically invalidates when:
-- Source files change
-- Test files change
-- Dependencies change
-- Configuration files change (tsconfig.json, .mocharc.*, package.json)
-
-### CI Caching
-
-BitGoJS CI uses both GitHub Actions cache and Nx cache for optimal performance:
-
-**GitHub Actions Cache**:
-- Caches `node_modules` and `modules/*/node_modules`
-- Caches `.nx/cache` and `modules/*/dist` directories
-- Cache keys include source file hashes for proper invalidation
-
-**Nx Cache**:
-- Automatically enabled in CI (via `useNx: true` in lerna.json)
-- Caches build outputs and test results
-- Respects task dependencies (tests depend on builds)
-
-**Skipping Cache**:
-- Add the `SKIP_CACHE` label to a PR to bypass all caching
-- This forces fresh installs and builds
-- When `SKIP_CACHE` is used:
-  - GitHub Actions cache is not restored
-  - Nx caching is disabled (`NX_SKIP_NX_CACHE=true`)
-  - All tasks run fresh without any caching
-
-**Troubleshooting**:
-If you encounter module resolution errors in CI:
-```bash
-# Option 1: Use --skip-nx-cache flag
-yarn unit-test --skip-nx-cache
-
-# Option 2: Clear cache and rebuild
-yarn clean-cache
-yarn build
-```
-
