+# Debugging Cache Issues
+
+## Diagnostic Tools
+
+### `--summarize`
+
+Generates a JSON file with all hash inputs. Compare two runs to find differences.
+
+```bash
+turbo build --summarize
+# Creates .turbo/runs/<run-id>.json
+```
+
+The summary includes:
+
+- Global hash and its inputs
+- Per-task hashes and their inputs
+- Environment variables that affected the hash
+
+**Comparing runs:**
+
+```bash
+# Run twice, compare the summaries
+diff .turbo/runs/<first-run>.json .turbo/runs/<second-run>.json
+```
+
+### `--dry` / `--dry=json`
+
+See what would run without executing anything:
+
+```bash
+turbo build --dry
+turbo build --dry=json  # machine-readable output
+```
+
+Shows cache status for each task without running them.
+
+### `--force`
+
+Skip reading cache, re-execute all tasks:
+
+```bash
+turbo build --force
+```
+
+Useful to verify tasks actually work (not just cached results).
+
+## Unexpected Cache Misses
+
+**Symptom:** Task runs when you expected a cache hit.
+
+### Environment Variable Changed
+
+Check if an env var in the `env` key changed:
+
+```json
+{
+  "tasks": {
+    "build": {
+      "env": ["API_URL", "NODE_ENV"]
+    }
+  }
+}
+```
+
+Different `API_URL` between runs = cache miss.
+
+### .env File Changed
+
+`.env` files aren't tracked by default. Add to `inputs`:
+
+```json
+{
+  "tasks": {
+    "build": {
+      "inputs": ["$TURBO_DEFAULT$", ".env", ".env.local"]
+    }
+  }
+}
+```
+
+Or use `globalDependencies` for repo-wide env files:
+
+```json
+{
+  "globalDependencies": [".env"]
+}
+```
+
+### Lockfile Changed
+
+Installing/updating packages changes the global hash.
+
+### Source Files Changed
+
+Any file in the package (or in `inputs`) triggers a miss.
+
+### turbo.json Changed
+
+Config changes invalidate the global hash.
+
+## Incorrect Cache Hits
+
+**Symptom:** Cached output is stale/wrong.
+
+### Missing Environment Variable
+
+Task uses an env var not listed in `env`:
+
+```javascript
+// build.js
+const apiUrl = process.env.API_URL;  // not tracked!
+```
+
+Fix: add to task config:
+
+```json
+{
+  "tasks": {
+    "build": {
+      "env": ["API_URL"]
+    }
+  }
+}
+```
+
+### Missing File in Inputs
+
+Task reads a file outside default inputs:
+
+```json
+{
+  "tasks": {
+    "build": {
+      "inputs": [
+        "$TURBO_DEFAULT$",
+        "../../shared-config.json"  // file outside package
+      ]
+    }
+  }
+}
+```
+
+## Useful Flags
+
+```bash
+# Only show output for cache misses
+turbo build --output-logs=new-only
+
+# Show output for everything (debugging)
+turbo build --output-logs=full
+
+# See why tasks are running
+turbo build --verbosity=2
+```
+
+## Quick Checklist
+
+Cache miss when expected hit:
+
+1. Run with `--summarize`, compare with previous run
+2. Check env vars with `--dry=json`
+3. Look for lockfile/config changes in git
+
+Cache hit when expected miss:
+
+1. Verify env var is in `env` array
+2. Verify file is in `inputs` array
+3. Check if file is outside package directory

+# Remote Caching
+
+Share cache artifacts across your team and CI pipelines.
+
+## Benefits
+
+- Team members get cache hits from each other's work
+- CI gets cache hits from local development (and vice versa)
+- Dramatically faster CI runs after first build
+- No more "works on my machine" rebuilds
+
+## Vercel Remote Cache
+
+Free, zero-config when deploying on Vercel. For local dev and other CI:
+
+### Local Development Setup
+
+```bash
+# Authenticate with Vercel
+npx turbo login
+
+# Link repo to your Vercel team
+npx turbo link
+```
+
+This creates `.turbo/config.json` with your team info (gitignored by default).
+
+### CI Setup
+
+Set these environment variables:
+
+```bash
+TURBO_TOKEN=<your-token>
+TURBO_TEAM=<your-team-slug>
+```
+
+Get your token from Vercel dashboard → Settings → Tokens.
+
+**GitHub Actions example:**
+
+```yaml
+- name: Build
+  run: npx turbo build
+  env:
+    TURBO_TOKEN: ${{ secrets.TURBO_TOKEN }}
+    TURBO_TEAM: ${{ vars.TURBO_TEAM }}
+```
+
+## Configuration in turbo.json
+
+```json
+{
+  "remoteCache": {
+    "enabled": true,
+    "signature": false
+  }
+}
+```
+
+Options:
+
+- `enabled`: toggle remote cache (default: true when authenticated)
+- `signature`: require artifact signing (default: false)
+
+## Artifact Signing
+
+Verify cache artifacts haven't been tampered with:
+
+```bash
+# Set a secret key (use same key across all environments)
+export TURBO_REMOTE_CACHE_SIGNATURE_KEY="your-secret-key"
+```
+
+Enable in config:
+
+```json
+{
+  "remoteCache": {
+    "signature": true
+  }
+}
+```
+
+Signed artifacts can only be restored if the signature matches.
+
+## Self-Hosted Options
+
+Community implementations for running your own cache server:
+
+- **turbo-remote-cache** (Node.js) - supports S3, GCS, Azure
+- **turborepo-remote-cache** (Go) - lightweight, S3-compatible
+- **ducktape** (Rust) - high-performance option
+
+Configure with environment variables:
+
+```bash
+TURBO_API=https://your-cache-server.com
+TURBO_TOKEN=your-auth-token
+TURBO_TEAM=your-team
+```
+
+## Cache Behavior Control
+
+```bash
+# Disable remote cache for a run
+turbo build --remote-cache-read-only  # read but don't write
+turbo build --no-cache                # skip cache entirely
+
+# Environment variable alternative
+TURBO_REMOTE_ONLY=true  # only use remote, skip local
+```
+
+## Debugging Remote Cache
+
+```bash
+# Verbose output shows cache operations
+turbo build --verbosity=2
+
+# Check if remote cache is configured
+turbo config
+```
+
+Look for:
+
+- "Remote caching enabled" in output
+- Upload/download messages during runs
+- "cache hit, replaying output" with remote cache indicator
