+# Contribution Guide
+Contibutions are very welcome!
+
+## Non-code contributions
+If you are not a programmer, you can still contribute by:
+
+- Adding discussion items over at the [Discussions page](https://github.com/christiaangoossens/hass-oidc-auth/discussions) if you have a question, feature idea or a setup you would like to show off.
+- Helping others in issues and discussion posts.
+- Voting on polls and providing input.
+- If you want to, contributing financially through [Github Sponsors](https://github.com/sponsors/christiaangoossens)
+
+## Code contributions
+You may also submit Pull Requests (PRs) to add features yourself! You can find a list that we are currently working on below. Please note that workflows will be run on your pull request and a pull request will only be merged when all checks pass and a review has been conducted (together with a manual test).
+
+### Development
+This project uses the Rye package manager for development. You can find installation instructions here: https://rye.astral.sh/guide/installation/. Start by installing the dependencies using rye sync and then point your editor towards the environment created in the .venv directory.
+You can then run Home Assistant and put the `custom_components/auth_oidc` directory in your HA `config` folder.
+
+### Docker Compose Development Environment
+You can also use the following Docker Compose configuration to automatically start up the latest HA release with the `auth_oidc` integration:
+
+```
+services:
+  homeassistant:
+    container_name: homeassistant
+    image: "ghcr.io/home-assistant/home-assistant:stable"
+    volumes:
+      - ./config:/config
+      - ./custom_components/auth_oidc:/config/custom_components/auth_oidc
+      - /etc/localtime:/etc/localtime:ro
+    ports:
+      - 8123:8123
+```
+
+# Found a security issue?
+Please see [SECURITY.md](./SECURITY.md) for more information on how to submit your security issue securely. You can find previously found vulnerablities and their corresponding security advisories at the [Security Advisories page](https://github.com/christiaangoossens/hass-oidc-auth/security/advisories).
+
+# Roadmap
+The following features are on the roadmap:
+
+## Better user experience
+*Copied from https://github.com/christiaangoossens/hass-oidc-auth/issues/19*
+
+Current status on the user experience:
+
+- I cannot change the login screen as all of this is hard coded in the frontend code. So, I am stuck with the title of "Just checking" and without any description or even a title for the input box. Changing this would require a PR on the Home Assistant frontend repository.
+  - If anyone can refactor their code to allow integrations (Auth Providers) to send custom translations to the frontend when sending the form (here: [custom_components/auth_oidc/provider.py, line 302](https://github.com/christiaangoossens/hass-oidc-auth/blob/main/custom_components/auth_oidc/provider.py#L302)), such that I can send custom translation keys for the title (instead of just using the `mfa` version), description and input label, I would be very happy to accept a PR here as well that accomplishes that.
+  - Bonus points if it uses the same translation system you would use for any normal setup/config flow in the UI.
+  - Extra bonus points if we can add a button or link besides it that allows for opening the start of the OIDC flow there too, within the description for instance.
+
+- I cannot redirect you to the start of the OIDC process yet, both on mobile and on desktop. Whenever [the PR](https://github.com/home-assistant/frontend/pull/23204) gets merged and a Home Assistant version that's includes the PR is released (or planned), I will hopefully be able to get something like that to work on desktop.
+  - It likely will not work on mobile, as the PR that's now approved only does it for desktop, I tested mobile with that code 2 years ago and it didn't work. I will contact someone on the Android team to see if we can make that happen too at some point.
+    - Mobile will need to open the `window.open` call using Android Custom Tab (Android) / SFSafariViewController (iOS) instead of the normal webview. It seems that external links didn't work at all when I tried it.
+
+PR's that improve the user experience are welcome, but they should be stable and preferably hack as little as possible.
+
+## Tests
+The project still needs the following automated tests on every PR:
+
+- Spin up Home Assistant (both the required version from the `hacs.json` and the latest version) and verify that it starts up with no warnings or errors
+- Normal pytest unit testing (https://developers.home-assistant.io/docs/development_testing/)
+  - You might be able to re-use some unit tests from the original implementation by @elupus: https://github.com/home-assistant/core/pull/32926 or from it's inspired work by @allenporter: https://github.com/allenporter/home-assistant-openid-auth-provider/tree/main/tests
+- Integration test that performs an automatic run-through of an entire flow with an example/mocked OIDC provider, either in Python code or using an external tool (such as Playwright)
+
+Together, these should test the following:
+- The integration registers correctly without any errors (spin-up test)
+- The integration works with both the minimum HA version as well as the latest HA version (spin-up test)
+- Configuration can be set without any errors (unit test)
+- Configuration has the correct effects (unit test)
+- Code works correctly on its own (unit test)
+- Full flow is functional and displays as expected, including integration with an external OIDC provider (integration test)
+
+Preferably, we run all tests on every PR to make manual testing unnecessary.
+
+## Better configuration experience
+As a conclusion to the poll (https://github.com/christiaangoossens/hass-oidc-auth/discussions/6), it seems that the best option would be to keep the current YAML configuration for advanced uses and add a UI configuration for the common providers.
+
+I planned for the following user flow:
+
+1. Add integration in the HA UI
+2. Get config dialog with a selector for which OIDC provider you are using
+3. Preconfigure claim configuration using the chosen provider
+4. Have user input client id & discovery URL with an instruction to configure as public client
+5. (Optionally) allow users to choose confidential client and input client secret
+6. Check these fields by requesting the discovery, JWKS
+7. Ask user if they want to enable groups and allow them to input the correct group name for both roles
+8. (Optionally) allow users to enable user linking, explain the issues to them with leaving it enabled and allow disabling later
+9. Inform users that advanced options are only available in YAML, such as networking settings or specific claim configurations
+10. Have the user perform one login to check that all the fields are correct, just as any OAuth2 integration would, preferably using our oidc_provider
+11. Save the integration and request restart to enable it (if necessary)
+
+While I welcome adding configuration by UI, it's not at the top of my priority list. Ask me in the PR if you have any other suggestions and don't forget to add tests for this too. Existing YAML configuration should also remain unaffected, whenever possible.

-Provides an OIDC implementation for Home Assistant.
+Provides an OpenID Connect (OIDC) implementation for Home Assistant through a custom component/integration. Through this integration, you can create an SSO (single-sign-on) environment within your self-hosted application stack / homelab.
 
 ### Background
 If you would like to read the background/open letter that lead to this component, please see https://community.home-assistant.io/t/open-letter-for-improving-home-assistants-authentication-system-oidc-sso/494223. It is currently one of the most upvoted feature requests for Home Assistant.
 
-## How to use
+## Installation guide
-### Installation
 
-Add this repository to [HACS](https://hacs.xyz/).
+1. Add this repository to [HACS](https://hacs.xyz/).
 
 [![Open your Home Assistant instance and open a repository inside the Home Assistant Community Store.](https://my.home-assistant.io/badges/hacs_repository.svg)](https://my.home-assistant.io/redirect/hacs_repository/?owner=christiaangoossens&repository=hass-oidc-auth&category=Integration)
 
-Update your `configuration.yaml` file with
+2. Add the YAML configuration that matches your OIDC provider to `configuration.yaml`. See the [Configuration Guide](./docs/configuration.md) for more details or pick your OIDC provider below:
+
+    | <img src="https://goauthentik.io/img/icon_top_brand_colour.svg" width="100"> | <img src="https://www.authelia.com/images/branding/logo-cropped.png" width="100"> | <img src="https://github.com/user-attachments/assets/4ceb2708-9f29-4694-b797-be833efce17d" width="100"> |
+    |:-----------------------------------------------------------------------------------------:|:-------------------------------------------------------------------------------------:|:---------------------------------------------------------------------------------------:|
+    | [Authentik](./docs/provider-configurations/authentik.md)                                       | [Authelia](./docs/provider-configurations/authelia.md)                                     | [Pocket ID](./docs/provider-configurations/pocket-id.md)                                     |
+
+    By default, the integration assumes you configure Home Assistant as a **public client** and thus only specify the `client_id` and no `client_secret`. For example, your configuration might look like:
 
     ```yaml
     auth_oidc:
-    client_id: ""
+        client_id: "example"
-    discovery_url: ""
+        discovery_url: "https://example.com/.well-known/openid-configuration"
     ```
 
-Register your client with your OIDC Provider (e.g. Authentik/Authelia) as a public client and get the client_id. Then, use the obtained client_id and discovery URLs to fill the fields in `configuration.yaml`.
+    When registering Home Assistant at your OIDC provider, use `<your HA URL>/auth/oidc/callback` as the callback URL and select 'public client'. You should now get the `client_id` and `issuer_url` or `discovery_url` to fill in.
 
-For example:
+3. Restart Home Assistant
-```yaml
-auth_oidc:
-   client_id: "someValueForTheClientId"
-   discovery_url: "https://example.com/application/o/application/.well-known/openid-configuration"
-```
 
-Afterwards, restart Home Assistant.
+4. Login through the OIDC Welcome URL at `<your HA URL>/auth/oidc/welcome`. You will have to go there manually for now. For example, it might be located at http://homeassistant.local:8123/auth/oidc/welcome.
 
-### Login
+More (detailed) usage instructions can be found in the [Usage Guide](./docs/usage.md).
-You should now be able to see a second option on your login screen ("OpenID Connect (SSO)"). It provides you with a single input field.
 
-Sadly, the user experience is pretty poor right now. Go to `/auth/oidc/welcome` (for example `https://hass.io/auth/oidc/welcome`, replace the URL with your Home Assistant URL) and follow the prompts provided to login, then copy the code into the input field from before. You should now login automatically with your username from SSO.
+## Contributions
+Contibutions are very welcome! If you program in Python or have worked with Home Assistant integrations before, please try to contribute. A list of requested contributions/future goals is in the [Contribution Guide](./CONTRIBUTING.md).
 
-> [!TIP]
+Please see the [Contribution Guide](./CONTRIBUTING.md) for more information.
-> You can use a different device to login instead. Open the `/auth/oidc/welcome` link on device A and then type the obtained code into the normal HA login on device B (can also be the mobile app) to login.
 
-## Development
+### Found a security issue?
-This project uses the Rye package manager for development. You can find installation instructions here: https://rye.astral.sh/guide/installation/.

+# Reporting Security Issues
+
+With the nature of the integration, security issues and bugs are taken very seriously. I appreciate your efforts to responsibly disclose your findings and I will acknowledge your finding in the security advisory and release notes of the release that fixes your vulnerability. Together, we will keep the Home Assistant community safe.
+
+To report a security issue, please use the GitHub Security Advisory ["Report a Vulnerability"](https://github.com/christiaangoossens/hass-oidc-auth/security/advisories/new) tab. **Do not make a public issue for your security vulnerability!**
+
+I (@christiaangoossens) will review security advisories regularly and send you a response indicating next steps in handling your report. This might include fixing the vulnerability before disclosing its nature, or working together in a private branch on a fix.
+
+Please note that this repository is maintained on a volunteer basis, I will try to respond quickly, but no guarantees.
+
+If your bug has to do with a third party package, please have it fixed there first, such that we can include a fixed version in an update of hass-oidc-auth.
+If you found a security vulnerability in Home Assistant itself, please report it at https://www.home-assistant.io/security/
+
+## Non qualifying vulnerabities
+Some vulnerabilities do not qualify for fixing in a security patch. The Home Assistant team has made a list of them over at https://www.home-assistant.io/security/#non-qualifying-vulnerabilities.

+# Configuration methods
+
+Currently, the only available configuration method is YAML in your `configuration.yaml` file. In the future, we will also add limited UI configuration for the most common configurations (Authentik, Authelia and Pocket-ID). Advanced users will need to use the YAML configuration in any case.
+
+# YAML Configuration
+For now, this integration is configured using YAML in your `configuration.yaml` file. By default, only two fields are required:
+
+```yaml
+auth_oidc:
+    client_id: ""
+    discovery_url: ""
+```
+
+The default settings assume that you configure Home Assistant as a **public client**, without a client secret. If so, you should only need to provide the `client_id` from your OIDC provider and it's discovery URL (ending in `.well-known/openid-configuration`).
+You don't have to configure other settings in most cases, as they have secure defaults set. If your provider requires manually configuring the callback URL, use `<your HA URL>/auth/oidc/callback`.
+
+## Provider Configurations
+Here are some documentation links for specific providers that you may want to follow:

+|:-----------------------------------------------------------------------------------------:|:-------------------------------------------------------------------------------------:|:---------------------------------------------------------------------------------------:|
+| [Authentik](./provider-configurations/authentik.md)                                       | [Authelia](./provider-configurations/authelia.md)                                     | [Pocket ID](./provider-configurations/pocket-id.md)                                     |
+
+
+Are you using another provider? Another user might have added configuration instructions here: [Other providers](./provider-configurations/other.md)
+
+## Common Configurations
+### Configuring Client Secret
+If you want to configure Home Assistant as a **confidential client**, you should provide the client secret as well. An example configuration might look like this:
+
+```yaml
+auth_oidc:
+    client_id: ""
+    client_secret: !secret oidc_client_secret
+    discovery_url: ""
+```
+
+You should use the Home Assistant secrets helper (`!secret`) to make sure you store secrets securely. See https://www.home-assistant.io/docs/configuration/secrets/ for more information.
+
+> [!IMPORTANT]  
+> Most users will not experience any benefits from using a confidential client, as using properly configured redirect URLs + PKCE already provides enough security in a home setting and using a client secret introduces the risk of it getting lost/stolen/put on the internet. Do not use a confidential setup if you don't know what you are doing.
+
+### Configuring roles & scopes or OIDC settings
+
+If your provider isn't listed above, you might want to configure OIDC settings yourself. Here's an example configuration for that use case:
+
+```yaml
+auth_oidc:
+    client_id: ""
+    discovery_url: ""
+    id_token_signing_alg: <HS256 or RS256>
+    groups_scope: <groups scope>
+    claims:
+        display_name: <display name claim from your provider>
+        username: <username claim from your provider>
+        groups: <groups claim from your provider>
+    roles:
+        admin: <group name to use for admins>
+        user: <group name to use for users>
+```
+
+If you configure the user role, OIDC users that have neither configured group name will be rejected! If you configure the admin role, users with that role will receive administrator rights in Home Assistant automatically upon login.
+
+### Configuring a display name for your OIDC provider
+If you would like to change the default name on the OIDC welcome screen and Home Assistant login screens from `OpenID Connect (SSO)` to your own display name, you can set the `display_name` configuration property.
+
+```yaml
+auth_oidc:
+    client_id: ""
+    discovery_url: ""
+    display_name: "Example"
+```
+
+This will show the provider on the login screen as: "Login with Example".
+
+### Migrating from HA username/password users to OIDC users
+If you already have users created within Home Assistant and would like to re-use the current user profile for your OIDC login, you can (temporarily) enable `features.automatic_user_linking`, with the following config (example):
+
+```yaml
+auth_oidc:
+    client_id: "someValueForTheClientId"
+    discovery_url: "https://example.com/application/o/application/.well-known/openid-configuration"
+    features:
+        automatic_user_linking: true
+```
+
+Upon login, OIDC users will then automatically be linked to the HA user with the same username. It's recommended to **only enable this temporarily** as it may pose a security risk. You should disable it after linking all your users, as existing links will still work if you disable it, but no new links will be created.
+
+> [!CAUTION]
+> Any OIDC user with a username corresponding to a user in Home Assistant can get access to that user and all its rights/configuration.
+
+> [!CAUTION]
+> MFA is ignored when using this setting, thus bypassing any MFA configuration the user has originally configured, as long as the username is an exact match. This is dangerous if you are not aware of it!
+
+### Using a private certificate authority
+If you use a private certificate authority to secure your OIDC provider, you must configure the root certificates of your private certificate authority. Otherwise you will get an error (`[SSL: CERTIFICATE_VERIFY_FAILED]`) when connecting to the OIDC provider.
+
+You can either make the CA known to the entire operating system or configure only this component to use the CA. If you want to only use your private CA with this integration, you can specify it via `network.tls_ca_path`:
+
+```yaml
+auth_oidc:
+    network:
+        tls_ca_path: /path/to/private-ca.pem
+```
+
+If you want to deactivate the validation of all TLS certificates for test purposes, you can do this via `network.tls_verify: false`:
+
+```yaml
+auth_oidc:
+    network:
+        tls_verify: false
+```
+
+> [!CAUTION]
+> Do not disable `tls_verify` in a production setting or when your Home Assistant installation is exposed outside of your network. If disabled, man-in-the-middle attacks can be used to change the provider configuration to allow fake tokens to be used.
+
+## All configuration Options
+
+Here's a table of all options that you can set:
+
+| Option                      | Type     | Required | Default             | Description                                                                                             |
+|-----------------------------|----------|----------|----------------------|---------------------------------------------------------------------------------------------------------|
+| `client_id`                 | `string` | Yes      |                      | The Client ID as registered with your OpenID Connect provider.                                        |
+| `client_secret`            | `string` | No       |                      | The Client Secret for enabling confidential client mode.                                             |
+| `discovery_url`            | `string` | Yes      |                      | The OIDC well-known configuration URL.                                                                |
+| `display_name`              | `string` | No       | `"OpenID Connect (SSO)"` | The name to display on the login screen, both for the Home Assistant screen and the OIDC welcome screen.                                                                |
+| `id_token_signing_alg`       | `string` | No       | `RS256`              | The signing algorithm that is used for your id_tokens.
+| `groups_scope`  | `string` | No       | `groups`           | Override the default grups scope with another scope of your choice. |
+| `features.automatic_user_linking`   | `boolean`| No       | `false`          | Automatically links users to existing Home Assistant users based on the OIDC username claim. Disabled by default for security. When disabled, OIDC users will get their own new user profile upon first login.     |
+| `features.automatic_person_creation` | `boolean` | No       | `true`          | Automatically creates a person entry for new user profiles created by this integration. Recommended if you would like to assign presence detection to OIDC users.                                            |
+| `features.disable_rfc7636`  | `boolean`| No       | `false`         | Disables PKCE (RFC 7636) for OIDC providers that don't support it. You should not need this with most providers.                                    |
+| `features.include_groups_scope`  | `boolean` | No       | `true`           | Include the 'groups' scope in the OIDC request. Set to `false` to exclude it. |
+| `claims.display_name`      | `string` | No       | `name`                     | The claim to use to obtain the display name.
+| `claims.username`         | `string` | No       | `preferred_username`                     | The claim to use to obtain the username.

+| `roles.admin`            | `string` | No       | `admins`                     | Group name to require for users to get the 'admin' role in Home Assistant. Defaults to 'admins', the default group name for admins in Authentik. Doesn't do anything if no groups claim is found in your token. |
+| `roles.user`            | `string` | No       |                     | Group name to require for users to get the 'user' role in Home Assistant. Defaults to giving all users this role, unless configured. |

+# How do I use the OIDC Integration for Home Assistant?
+
+Here's a step by step guide to use the integration:
+
+### Step 1: HACS
+Install the integration through [HACS](https://hacs.xyz/). You can add it automatically using the button below, or use the Github URL and type `Integration` in the manual Custom Repository add dialog.
+
+[![Open your Home Assistant instance and open a repository inside the Home Assistant Community Store.](https://my.home-assistant.io/badges/hacs_repository.svg)](https://my.home-assistant.io/redirect/hacs_repository/?owner=christiaangoossens&repository=hass-oidc-auth&category=Integration)
+
+
+### Step 2: Configuration of the integration
+The integration is currently configurable through YAML only. See the [Configuration Guide](./docs/configuration.md) for more details or pick your OIDC provider below:
+
+| <img src="https://goauthentik.io/img/icon_top_brand_colour.svg" width="100"> | <img src="https://www.authelia.com/images/branding/logo-cropped.png" width="100"> | <img src="https://github.com/user-attachments/assets/4ceb2708-9f29-4694-b797-be833efce17d" width="100"> |
+|:-----------------------------------------------------------------------------------------:|:-------------------------------------------------------------------------------------:|:---------------------------------------------------------------------------------------:|
+| [Authentik](./provider-configurations/authentik.md)                                       | [Authelia](./provider-configurations/authelia.md)                                     | [Pocket ID](./provider-configurations/pocket-id.md)                                     |
+
+By default, the integration assumes you configure Home Assistant as a **public client** and thus only specify the `client_id` and no `client_secret`. For example, your configuration might look like:
+
+```yaml
+auth_oidc:
+    client_id: "example"
+    discovery_url: "https://example.com/.well-known/openid-configuration"
+```
+
+When registering Home Assistant at your OIDC provider, use `<your HA URL>/auth/oidc/callback` as the callback URL and select 'public client'. You should now get the `client_id` and `issuer_url` or `discovery_url` to fill in.
+
+### Step 3: Restart
+Restart Home Assistant. You can do so by going to the Reparations/Update section in Home Assistant.
+
+### Step 4: Go to the OIDC login screen
+After restarting Home Assistant, you should now be able to get to the login screen. You can find it at `<your HA URL>/auth/oidc/welcome`. You will have to go there manually for now. For example, it might be located at http://homeassistant.local:8123/auth/oidc/welcome.
+
+It should look like this:
+
+![image](https://github.com/user-attachments/assets/7320b7d3-b9f9-4268-ba1f-4deb0c6805ea)
+
+If you have configured everything correctly, you should be redirected to your OIDC Provider after clicking the button. Please login there.
+
+You should return to a screen like this:
+
+![image](https://github.com/user-attachments/assets/d9c305bd-4a93-4a97-ae55-dba6361d92c8)
+
+Either click the automatic sign in button or copy the code.
+This screen will give you a one-time code to login that expires in 5 minutes.
+
+#### Step 4a: Automatic login
+If you would like to login automatically, click the button. It will log you in to your user in the current browser window.
+
+#### Step 4b: Code login
+If you would like to login using the code, go to your normal Home Assistant URL without any user logged in, such as on your mobile device/wall tablet/smart watch. You will now see the following screen:
+
+![image](https://github.com/user-attachments/assets/4ed2b408-53e4-429e-920a-7628ddbcfc02)
+
+If you don't, you likely see:
+
+![image](https://github.com/user-attachments/assets/80629c60-793e-4933-8b45-283234798ffb)
+
+If so, click "OpenID Connect (SSO)" to get to the first screen. If you have configured a [display name](./configuration.md#configuring-a-display-name-for-your-oidc-provider), that will show instead.
+
+Enter your code into the single input field:
+
+![image](https://github.com/user-attachments/assets/f031a41c-5a85-44b8-8517-3feabaa44fd5)
+
+Upon clicking login, you should now login.
+If the code is wrong, you will see this instead:
+
+![image](https://github.com/user-attachments/assets/317d20e4-0e10-40f7-bb68-5cf456faf87d)
+
+#### Step 5: Logged in
+You will be logged in after following this guide.
+
+With the default configuration, [a person entry](https://www.home-assistant.io/integrations/person/) will be created for every new OIDC user logging in. New OIDC users will get their own fresh user, linked to their persistent ID (subject) at the OpenID Connect provider. You may change your name, username or email at the provider and still have the same Home Assistant user profile.
+
+# How can I make this easier for my users?
+
+You can link the user directly to one of these following URLs:
+
+- `/auth/oidc/welcome` (if you would like a nice welcome screen for your users)
+- `/auth/oidc/redirect` (if you would like to just redirect them without a welcome screen)
+
+For a seamless user experience, configure a new domain on your proxy to redirect to the `/auth/oidc/welcome` path or configure that path on your homelab dashboard or in your OIDC provider (such as in the app settings in Authentik). Users will then always start on the OIDC welcome page, which will allow them to visit the dashboard if they are already logged in.
+
+*Note: do not replace the standard path with a redirect to the OIDC screen. This breaks login with code.*
