+This page explains the base concepts of Traefik.
+
+---
+
+## Introduction
+
+Traefik is based on the concept of EntryPoints, Routers, Middelwares and Services.
+
+The main features include dynamic configuration, automatic service discovery, and support for multiple backends and protocols.
+
+1. [EntryPoints](../routing/entrypoints.md "Link to docs about EntryPoints"): EntryPoints are the network entry points into Traefik. They define the port which will receive the packets, and whether to listen for TCP or UDP.
+
+2. [Routers](../routing/routers/index.md "Link to docs about routers"): A router is in charge of connecting incoming requests to the services that can handle them.
+
+3. [Middlewares](../middlewares/overview.md "Link to docs about middlewares"): Attached to the routers, middlewares can modify the requests or responses before they are sent to your service
+
+4. [Services](../routing/services/index.md "Link to docs about services"): Services are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
 
 ## Edge Router
 
-Traefik is an _Edge Router_, it means that it's the door to your platform, and that it intercepts and routes every incoming request:
-it knows all the logic and every rule that determine which services handle which requests (based on the [path](../routing/routers/index.md#rule), the [host](../routing/routers/index.md#rule), [headers](../routing/routers/index.md#rule), [and so on](../routing/routers/index.md#rule) ...).

+## How Traefik is Storing and Serving TLS Certificates?
+
+### Storing TLS Certificates
+
+[TLS](../https/tls.md "Link to Traefik TLS docs") certificates are either provided directly by the [dynamic configuration](./configuration-overview.md#the-dynamic-configuration "Link to dynamic configuration overview") from [providers](../https/tls.md#user-defined "Link to the TLS configuration"),
+or by [ACME resolvers](../https/acme.md#providers "Link to ACME resolvers"), which act themselves as providers internally.
+
+For each TLS certificate, Traefik produces an identifier used as a key to store it.
+This identifier is constructed as the alphabetically ordered concatenation of the SANs `DNSNames` and `IPAddresses` of the TLScertificate.
+
+#### Examples:
+
+| X509v3 Subject Alternative Name         | TLS Certificate Identifier  |
+|-----------------------------------------|-----------------------------|
+| `DNS:example.com, IP Address:127.0.0.1` | `127.0.0.1,example.com`     |
+| `DNS:example.com, DNS:*.example.com`    | `*.example.com,example.com` |
+
+The identifier is used to store TLS certificates in order to be later used to handle TLS connections.
+This operation happens each time there are configuration changes.
+
+If multiple TLS certificates are provided with the same SANs definition (same identifier), only the one processed first is kept.
+Because the dynamic configuration is aggregated from all providers,
+when processing it to gather TLS certificates,
+there is no guarantee of the order in which they would be processed.
+This means that along with configurations applied, it is possible that the TLS certificate retained for a given identifier differs.
+
+### Serving TLS Certificates
+
+For each incoming connection, Traefik is serving the "best" matching TLS certificate for the provided server name.
+
+The TLS certificate selection process narrows down the list of TLS certificates matching the server name,
+and then selects the last TLS certificate in this list after having ordered it by the identifier alphabetically.
+
+#### Examples:
+
+| Selected TLS Certificates Identifiers               | Sorted TLS Certificates Identifiers                 | Served Certificate Identifier |
+|-----------------------------------------------------|-----------------------------------------------------|-------------------------------|
+| `127.0.0.1,example.com`,`*.example.com,example.com` | `*.example.com,example.com`,`127.0.0.1,example.com` | `127.0.0.1,example.com`       |
+| `*.example.com,example.com`,`example.com`           | `*.example.com,example.com`,`example.com`           | `example.com`                 |
+
+### Caching TLS Certificates
+
+While Traefik is serving the best matching TLS certificate for each incoming connection,
+the selection process cost for each incoming connection is avoided thanks to a cache mechanism.
+
+Once a TLS certificate has been selected as the "best" TLS certificate for a server name,
+it is cached for an hour, avoiding the selection process for further connections.
+
+Nonetheless, when a new configuration is applied, the cache is reset.

+## Why does Let's Encrypt wildcard certificate renewal/generation with DNS challenge fail?
+
+If you're trying to renew wildcard certificates, with DNS challenge,
+and you're getting errors such as:

+
+In which case, you should make sure your infrastructure is properly set up for a

+In Kubernetes environment, CA certificate can be set in `clientAuth.secretNames`. See [TLSOption resource](../../routing/providers/kubernetes-crd#kind-tlsoption) for more details.

 - `NoClientCert`: disregards any client certificate.
 - `RequestClientCert`: asks for a certificate but proceeds anyway if none is provided.
-- `RequireAnyClientCert`: requires a certificate but does not verify if it is signed by a CA listed in `clientAuth.caFiles`.
-- `VerifyClientCertIfGiven`: if a certificate is provided, verifies if it is signed by a CA listed in `clientAuth.caFiles`. Otherwise proceeds without any certificate.

+## v2.10
+
+### Nomad Namespace
+
+In `v2.10`, the `namespace` option of the Nomad provider is deprecated, please use the `namespaces` options instead.
+
+### Kubernetes CRDs
+
+In `v2.10`, the Kubernetes CRDs API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.
+
+As the Kubernetes CRD provider still works with both API Versions (`traefik.io/v1alpha1` and `traefik.containo.us/v1alpha1`),
+it means that for the same kind, namespace and name, the provider will only keep the `traefik.io/v1alpha1` resource.
+
+In addition, the Kubernetes CRDs API Version `traefik.io/v1alpha1` will not be supported in Traefik v3 itself.
+
+Please note that it is a requirement to update the CRDs and the RBAC in the cluster before upgrading Traefik.
+To do so, please apply the required [CRDs](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml) and [RBAC](https://raw.githubusercontent.com/traefik/traefik/v2.10/docs/content/reference/dynamic-configuration/kubernetes-crd-rbac.yml) manifests for v2.10:
