+  - Please note that this support should be considered _partially_ implemented
+  - SSH ACLs status:
+    - Support `accept` and `check` (SSH can be enabled and used for connecting and authentication)
+    - Rejecting connections **are not supported**, meaning that if you enable SSH, then assume that _all_ `ssh` connections **will be allowed**.
+    - If you decied to try this feature, please carefully managed permissions by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your clients.
+    - We are currently improving our testing of the SSH ACLs, help us get an overview by testing and giving feedback.
+  - This feature should be considered dangerous and it is disabled by default. Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.

+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation
+in our community a harassment-free experience for everyone, regardless
+of age, body size, visible or invisible disability, ethnicity, sex
+characteristics, gender identity and expression, level of experience,
+education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open,
+welcoming, diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for
+our community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our
+  mistakes, and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or
+  political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in
+  a professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our
+standards of acceptable behavior and will take appropriate and fair
+corrective action in response to any behavior that they deem
+inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit,
+or reject comments, commits, code, wiki edits, issues, and other
+contributions that are not aligned to this Code of Conduct, and will
+communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also
+applies when an individual is officially representing the community in
+public spaces. Examples of representing our community include using an
+official e-mail address, posting via an official social media account,
+or acting as an appointed representative at an online or offline
+event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior
+may be reported to the community leaders responsible for enforcement
+at our Discord channel. All complaints
+will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and
+security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in
+determining the consequences for any action they deem in violation of
+this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior
+deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders,
+providing clarity around the nature of the violation and an
+explanation of why the behavior was inappropriate. A public apology
+may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued
+behavior. No interaction with the people involved, including
+unsolicited interaction with those enforcing the Code of Conduct, for
+a specified period of time. This includes avoiding interactions in
+community spaces as well as external channels like social
+media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards,
+including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or
+public communication with the community for a specified period of
+time. No public or private interaction with the people involved,
+including unsolicited interaction with those enforcing the Code of
+Conduct, is allowed during this period. Violating these terms may lead
+to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of
+community standards, including sustained inappropriate behavior,
+harassment of an individual, or aggression toward or disparagement of
+classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction
+within the community.

+# Connecting an Android client
+
+## Goal
+
+This documentation has the goal of showing how a user can use the official Android [Tailscale](https://tailscale.com) client with `headscale`.
+
+## Installation
+
+Install the official Tailscale Android client from the [Google Play Store](https://play.google.com/store/apps/details?id=com.tailscale.ipn) or [F-Droid](https://f-droid.org/packages/com.tailscale.ipn/).
+
+Ensure that the installed version is at least 1.30.0, as that is the first release to support custom URLs.
+
+## Configuring the headscale URL
+
+After opening the app, the kebab menu icon (three dots) on the top bar on the right must be repeatedly opened and closed until the _Change server_ option appears in the menu. This is where you can enter your headscale URL.
+
+A screen recording of this process can be seen in the `tailscale-android` PR which implemented this functionality: <https://github.com/tailscale/tailscale-android/pull/55>
+
+After saving and restarting the app, selecting the regular _Sign in_ option (non-SSO) should open up the headscale authentication page.

+# Setting custom DNS records
+
+## Goal
+
+This documentation has the goal of showing how a user can set custom DNS records with `headscale`s magic dns.
+An example use case is to serve apps on the same host via a reverse proxy like NGINX, in this case a Prometheus monitoring stack. This allows to nicely access the service with "http://grafana.myvpn.example.com" instead of the hostname and portnum combination "http://hostname-in-magic-dns.myvpn.example.com:3000".
+
+## Setup
+
+### 1. Change the configuration
+
+1. Change the `config.yaml` to contain the desired records like so:
+
+```yaml
+dns_config:
+  ...
+  extra_records:
+    - name: "prometheus.myvpn.example.com"
+      type: "A"
+      value: "100.64.0.3"
+
+    - name: "grafana.myvpn.example.com"
+      type: "A"
+      value: "100.64.0.3"
+  ...
+```
+
+2. Restart your headscale instance.
+
+Beware of the limitations listed later on!
+
+### 2. Verify that the records are set
+
+You can use a DNS querying tool of your choice on one of your hosts to verify that your newly set records are actually available in MagicDNS, here we used [`dig`](https://man.archlinux.org/man/dig.1.en):
+
+```
+$ dig grafana.myvpn.example.com
+
+; <<>> DiG 9.18.10 <<>> grafana.myvpn.example.com
+;; global options: +cmd
+;; Got answer:
+;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 44054
+;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1
+
+;; OPT PSEUDOSECTION:
+; EDNS: version: 0, flags:; udp: 65494
+;; QUESTION SECTION:

+
+;; ANSWER SECTION:

+;; WHEN: Sat Dec 31 11:46:55 CET 2022
+;; MSG SIZE  rcvd: 66
+```
+
+### 3. Optional: Setup the reverse proxy
+
+The motivating example here was to be able to access internal monitoring services on the same host without specifying a port:
+
+```
+server {
+    listen 80;
+    listen [::]:80;
+
+    server_name grafana.myvpn.example.com;
+
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_set_header Host $http_host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+}
+```
+
+## Limitations
+
+[Not all types of records are supported](https://github.com/tailscale/tailscale/blob/6edf357b96b28ee1be659a70232c0135b2ffedfd/ipn/ipnlocal/local.go#L2989-L3007), especially no CNAME records.

+# Connecting an iOS client
+
+## Goal
+
+This documentation has the goal of showing how a user can use the official iOS [Tailscale](https://tailscale.com) client with `headscale`.
+
+## Installation
+
+Install the official Tailscale iOS client from the [App Store](https://apps.apple.com/app/tailscale/id1470499037).
+
+Ensure that the installed version is at least 1.38.1, as that is the first release to support alternate control servers.
+
+## Configuring the headscale URL
+
+Ensure that the tailscale app is logged out before proceeding.
+
+Go to iOS settings, scroll down past game center and tv provider to the tailscale app and select it. The headscale URL can be entered into the _"ALTERNATE COORDINATION SERVER URL"_ box.
+
+> **Note**
+>
+> If the app was previously logged into tailscale, toggle on the _Reset Keychain_ switch.
+
+Restart the app by closing it from the iOS app switcher, open the app and select the regular _Sign in_ option (non-SSO), and it should open up to the headscale authentication page.
+
+Enter your credentials and log in. Headscale should now be working on your iOS device.

+# Configuring Headscale to use OIDC authentication
+
+In order to authenticate users through a centralized solution one must enable the OIDC integration.
+
+Known limitations:
+
+- No dynamic ACL support
+- OIDC groups cannot be used in ACLs
+
+## Basic configuration
+
+In your `config.yaml`, customize this to your liking:
+
+```yaml
+oidc:
+  # Block further startup until the OIDC provider is healthy and available
+  only_start_if_oidc_is_available: true
+  # Specified by your OIDC provider
+  issuer: "https://your-oidc.issuer.com/path"
+  # Specified/generated by your OIDC provider
+  client_id: "your-oidc-client-id"
+  client_secret: "your-oidc-client-secret"
+  # alternatively, set `client_secret_path` to read the secret from the file.
+  # It resolves environment variables, making integration to systemd's
+  # `LoadCredential` straightforward:
+  #client_secret_path: "${CREDENTIALS_DIRECTORY}/oidc_client_secret"
+
+  # Customize the scopes used in the OIDC flow, defaults to "openid", "profile" and "email" and add custom query
+  # parameters to the Authorize Endpoint request. Scopes default to "openid", "profile" and "email".
+  scope: ["openid", "profile", "email", "custom"]
+  # Optional: Passed on to the browser login request – used to tweak behaviour for the OIDC provider
+  extra_params:
+    domain_hint: example.com
+
+  # Optional: List allowed principal domains and/or users. If an authenticated user's domain is not in this list,
+  # the authentication request will be rejected.
+  allowed_domains:
+    - example.com
+  # Optional. Note that groups from Keycloak have a leading '/'.
+  allowed_groups:
+    - /headscale
+  # Optional.
+  allowed_users:
+    - alice@example.com
+
+  # If `strip_email_domain` is set to `true`, the domain part of the username email address will be removed.
+  # This will transform `first-name.last-name@example.com` to the user `first-name.last-name`
+  # If `strip_email_domain` is set to `false` the domain part will NOT be removed resulting to the following
+  # user: `first-name.last-name.example.com`
+  strip_email_domain: true
+```
+
+## Azure AD example
+
+In order to integrate Headscale with Azure Active Directory, we'll need to provision an App Registration with the correct scopes and redirect URI. Here with Terraform:
+
+```hcl
+resource "azuread_application" "headscale" {
+  display_name = "Headscale"
+
+  sign_in_audience = "AzureADMyOrg"
+  fallback_public_client_enabled = false
+
+  required_resource_access {
+    // Microsoft Graph
+    resource_app_id = "00000003-0000-0000-c000-000000000000"
+
+    resource_access {
+      // scope: profile
+      id   = "14dad69e-099b-42c9-810b-d002981feec1"
+      type = "Scope"
+    }
+    resource_access {
+      // scope: openid
+      id   = "37f7f235-527c-4136-accd-4a02d197296e"
+      type = "Scope"
+    }
+    resource_access {
+      // scope: email
+      id   = "64a6cdd6-aab1-4aaf-94b8-3cc8405e90d0"
+      type = "Scope"
+    }
+  }
+  web {
+    # Points at your running Headscale instance
+    redirect_uris = ["https://headscale.example.com/oidc/callback"]
+
+    implicit_grant {
+      access_token_issuance_enabled = false
+      id_token_issuance_enabled = true
+    }
+  }
+
+  group_membership_claims = ["SecurityGroup"]
+  optional_claims {
+    # Expose group memberships
+    id_token {
+      name = "groups"
+    }
+  }
+}
+
+resource "azuread_application_password" "headscale-application-secret" {
+  display_name          = "Headscale Server"
+  application_object_id = azuread_application.headscale.object_id
+}
+
+resource "azuread_service_principal" "headscale" {
+  application_id = azuread_application.headscale.application_id
+}
+
+resource "azuread_service_principal_password" "headscale" {
+  service_principal_id = azuread_service_principal.headscale.id
+  end_date_relative    = "44640h"
+}
+
+output "headscale_client_id" {
+  value = azuread_application.headscale.application_id
+}
+
+output "headscale_client_secret" {
+  value = azuread_application_password.headscale-application-secret.value
+}
+```
+
+And in your Headscale `config.yaml`:
+
+```yaml
+oidc:
+  issuer: "https://login.microsoftonline.com/<tenant-UUID>/v2.0"
+  client_id: "<client-id-from-terraform>"
+  client_secret: "<client-secret-from-terraform>"
+
+  # Optional: add "groups"
+  scope: ["openid", "profile", "email"]
+  extra_params:
+    # Use your own domain, associated with Azure AD
+    domain_hint: example.com
+    # Optional: Force the Azure AD account picker
+    prompt: select_account
+```
+
+## Google OAuth Example
+
+In order to integrate Headscale with Google, you'll need to have a [Google Cloud Console](https://console.cloud.google.com) account.
+
+Google OAuth has a [verification process](https://support.google.com/cloud/answer/9110914?hl=en) if you need to have users authenticate who are outside of your domain. If you only need to authenticate users from your domain name (ie `@example.com`), you don't need to go through the verification process.
+
+However if you don't have a domain, or need to add users outside of your domain, you can manually add emails via Google Console.
+
+### Steps
+
+1. Go to [Google Console](https://console.cloud.google.com) and login or create an account if you don't have one.
+2. Create a project (if you don't already have one).
+3. On the left hand menu, go to `APIs and services` -> `Credentials`
+4. Click `Create Credentials` -> `OAuth client ID`
+5. Under `Application Type`, choose `Web Application`
+6. For `Name`, enter whatever you like
+7. Under `Authorised redirect URIs`, use `https://example.com/oidc/callback`, replacing example.com with your Headscale URL.
+8. Click `Save` at the bottom of the form
+9. Take note of the `Client ID` and `Client secret`, you can also download it for reference if you need it.
+10. Edit your headscale config, under `oidc`, filling in your `client_id` and `client_secret`:
+
+```yaml
+oidc:
+  issuer: "https://accounts.google.com"
+  client_id: ""
+  client_secret: ""
+  scope: ["openid", "profile", "email"]
+```
+
+You can also use `allowed_domains` and `allowed_users` to restrict the users who can authenticate.

+# Better route management
+
+As of today, route management in Headscale is very basic and does not allow for much flexibility, including implementing subnet HA, 4via6 or more advanced features. We also have a number of bugs (e.g., routes exposed by ephemeral nodes)
+
+This proposal aims to improve the route management.
+
+## Current situation
+
+Routes advertised by the nodes are read from the Hostinfo struct. If approved from the the CLI or via autoApprovers, the route is added to the EnabledRoutes field in `Machine`.
+
+This means that the advertised routes are not persisted in the database, as Hostinfo is always replaced. In the same way, EnabledRoutes can get out of sync with the actual routes in the node.
+
+In case of colliding routes (i.e., subnets that are exposed from multiple nodes), we are currently just sending all of them in `PrimaryRoutes`... and hope for the best. (`PrimaryRoutes` is the field in `Node` used for subnet failover).
+
+## Proposal
+
+The core part is to create a new `Route` struct (and DB table), with the following fields:
+
+```go
+type Route struct {
+	ID          uint64 `gorm:"primary_key"`
+
+    Machine     *Machine
+    Prefix      IPPrefix
+
+    Advertised  bool
+    Enabled     bool
+    IsPrimary   bool
+
+
+    CreatedAt   *time.Time
+    UpdatedAt   *time.Time
+    DeletedAt   *time.Time
+}
+```
+
+- The `Advertised` field is set to true if the route is being advertised by the node. It is set to false if the route is removed. This way we can indicate if a later enabled route has stopped being advertised. A similar behaviour happens in the Tailscale.com control panel.
+
+- The `Enabled` field is set to true if the route is enabled - via CLI or autoApprovers.
+
+- `IsPrimary` indicates if Headscale has selected this route as the primary route for that particular subnet. This allows us to implement subnet failover. This would be fully automatic if there is more than subnet routers advertising the same network - which is the behaviour of Tailscale.com.
+
+## Stuff to bear in mind
+
+- We need to make sure to migrate the current `EnabledRoutes` of `Machine` into the new table.
+- When a node stops sharing a subnet, I reckon we should mark it both as not `Advertised` and not `Enabled`. Users should re-enable it if the node advertises it again.
+- If only one subnet router is advertising a subnet, we should mark it as primary.
+- Regarding subnet failover, the current behaviour of Tailscale.com is to perform the failover after 15 seconds from the node disconnecting from their control panel. I reckon we cannot do the same currently. Our maximum granularity is the keep alive period.
