+### Namespace Configuration
+
+Slaking supports two modes for watching Kubernetes namespaces:
+
+#### Watch All Namespaces (Default)
+By default, Slaking watches all namespaces in your cluster. This is the recommended configuration for most use cases.
+
+```bash
+# Environment configuration
+K8S_WATCH_ALL_NAMESPACES=true
+# K8S_NAMESPACES can be left empty or unset
+```
+
+**Benefits:**
+- Automatically picks up new namespaces
+- No need to maintain a list of namespaces
+- Works with any workload regardless of namespace
+- Simpler configuration
+
+#### Watch Specific Namespaces Only
+For environments where you want to limit Slaking's scope to specific namespaces.
+
+```bash
+# Environment configuration
+K8S_WATCH_ALL_NAMESPACES=false
+K8S_NAMESPACES=production,staging,monitoring
+```
+
+**Use Cases:**
+- Multi-tenant clusters with namespace isolation
+- Performance optimization for large clusters
+- Security requirements limiting cross-namespace access
+- Testing in specific environments only

+### Namespace Configuration
+
+Slaking supports two modes for watching Kubernetes namespaces:
+
+#### 🦥 Watch All Namespaces (Recommended)
+This is the default and recommended configuration. Slaking will monitor all namespaces in your cluster and only process logs from workloads that have the `slaking.enabled: "true"` annotation.
+
+**Environment Configuration:**
+```bash
+# Set to watch all namespaces
+K8S_WATCH_ALL_NAMESPACES=true
+# Leave K8S_NAMESPACES empty or unset
+```
+
+**Helm Configuration:**
+```bash
+helm install slaking slaking/slaking \
+  --set env.K8S_WATCH_ALL_NAMESPACES="true"
+```
+
+**Benefits:**
+- ✅ No need to specify namespaces manually
+- ✅ Automatically picks up new namespaces
+- ✅ Works with any workload regardless of namespace
+- ✅ Simpler configuration and maintenance
+
+#### 🎯 Watch Specific Namespaces Only
+For environments where you want to limit Slaking's scope to specific namespaces (e.g., for security or performance reasons).
+
+**Environment Configuration:**
+```bash
+# Disable watching all namespaces
+K8S_WATCH_ALL_NAMESPACES=false
+# Specify namespaces to watch
+K8S_NAMESPACES=production,staging,monitoring
+```
+
+**Helm Configuration:**
+```bash
+helm install slaking slaking/slaking \
+  --set env.K8S_WATCH_ALL_NAMESPACES="false" \
+  --set env.K8S_NAMESPACES="production,staging,monitoring"
+```
+
+**Use Cases:**
+- 🔒 Multi-tenant clusters where you want to isolate monitoring
+- 🚀 Performance optimization for large clusters
+- 🛡️ Security requirements that limit cross-namespace access
