-1. Set up Docker Swarm and [`abra`][abra]
-2. Deploy [`compose-stacks/traefik`][compose-traefik]
-2. `cp .envrc.sample .envrc`
-3. Edit `.envrc` - be sure to change `$DOMAIN` to something that resolves to
-   your Docker swarm box
-4. `direnv allow` (or `. .envrc`)
-5. `abra deploy`

+<!-- endmetadata -->
+
+## Basic usage
+
+1. Set up Docker Swarm and [`abra`](https://docs.coopcloud.tech/abra/)
+2. Deploy [`coop-cloud/traefik`](https://git.coopcloud.tech/coop-cloud/traefik)
+3. `abra app new matrix-synapse --secrets` (optionally with `--pass` if you'd like to save secrets in `pass`)
+4. `abra app config YOURAPPDOMAIN` - be sure to change `$DOMAIN` to something that resolves to your Docker swarm box
+5. `abra app deploy YOURAPPDOMAIN`
+6. Create an initial user: `abra app run YOURAPPDOMAIN app register_new_matrix_user -c /data/homeserver.yaml http://localhost:8008`
+
+## Tips & Tricks
+
+### Set Admin User
+
+`abra app cmd YOURAPPDOMAIN db set_admin <adminuser>`
+
+### Disabling federation
+
+- Use `DISABLE_FEDERATION=1` to turn off federation listeners
+- Don't use [`compose.matrix.yml`](https://git.coopcloud.tech/coop-cloud/traefik/src/branch/master/compose.matrix.yml) in your traefik config to keep the federation ports closed
+
+### Enabling federation
+
+See [`#27`](https://git.coopcloud.tech/coop-cloud/matrix-synapse/pulls/27) for more. Depending on your setup, using `SERVE_SERVER_WELLKNOWN=true` might work to start federating. Make sure you don't leave `DISABLE_FEDERATION=1` set!
+
+### Getting client discovery on a custom domain
+
+You'll need to deploy something like [this](https://git.autonomic.zone/ruangrupa/well-known-uris). This could be implemented in this recipe but we haven't merged it in yet. Change sets are welcome.
+
+### Telegram bridging
+
+> WIP docs
+
+Setting it up is a bit of a chicken/egg & chasing cats moment.
+
+You need to get your bot setup on the telegram side first and have these values:
+
+```
+api_id: ...
+api_hash: ...
+telegram_bot_token: ...
+```
+
+Here is a rough guide:
+
+```
+abra app secret insert <domain> telegram_api_hash v1 <secret>
+abra app secret insert <domain> telegram_bot_token v1 <secret>
+abra app secret generate -a <domain>
+
+abra app deploy <domain>
+abra app run matrix.fva.wtf telegram_bridge cat /data/registration.yaml
+abra app undeploy <domain>
+
+abra app secret rm <domain> telegram_as_token
+abra app secret insert <domain> telegram_as_token v1 <secret>
+
+abra app secret rm <domain> telegram_as_token
+abra app secret insert <domain> telegram_hs_token v1 <secret>
+
+abra app deploy <domain>
+```
+
+Some helpful documentation:
+
+- [`docs.mau.fi`](https://docs.mau.fi/bridges/python/setup/docker.html?bridge=telegram)
+- [`example-config.yaml`](https://mau.dev/mautrix/telegram/-/blob/master/mautrix_telegram/example-config.yaml)
+
+### Discord bridging
+
+> WIP docs
+
+Just as messy as the Telegram bridging above! Rough guide:
+
+- get a local copy of [`config.yaml`](https://github.com/matrix-org/matrix-appservice-discord/blob/develop/config/config.sample.yaml)
+- fill it out with the values you need, all the discord token stuff, etc.
+- run `mkdir -p data && cp config.yaml data/` then `docker run --rm -v data:/data halfshot/matrix-appservice-discord:v1.0.0 sh -c "cd /data && node /build/src/discordas.js -r -u "http://discordbridge:9005" -c config.yaml"`
+- this generates the app service registration configuration you need to feed to the homeserver
+- run secret generation for the `discord_db_password`, insert your `discord_bot_token`
+- run `abra app cp <domain> discord-registration.yaml app:/discord-data` (it has to be called `discord-registration.yaml`)
+- deploy the bridge & happy hacking
+
+Some helpful documentation:
+
+- [`matrix-org/matrix-appservice-discord` docs](https://github.com/matrix-org/matrix-appservice-discord#bridging-a-room)
+- [`t2bot.io/discord`](https://t2bot.io/discord/)
+
+### Signal bridging
+
+> WIP docs
+
+OK, it's also awful to set this up. Do you see a pattern emerging :)
+
+- fake that you have the required tokens:
+  - `abra app secret insert example.com signal_hs_token v1 foo`
+  - `abra app secret insert example.com signal_as_token v1 foo`
+- generate the database password:
+  - `abra app secret generate example.com -a`
+- deploy the thing and then check the `/data/registration.yaml`
+- rm the fake `signal_hs/as_token` values and re-insert the new ones from `registration.yaml`
+- re-deploy the whole thing and then it should come up, message `@signalbot:example.com` to test

+  # If no configuration is provided, a single job will be set up to delete expired
+  # events in every room daily.
+  #
+  # Each job's configuration defines which range of message lifetimes the job
+  # takes care of. For example, if 'shortest_max_lifetime' is '2d' and
+  # 'longest_max_lifetime' is '3d', the job will handle purging expired events in
+  # rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and
+  # lower than or equal to 3 days. Both the minimum and the maximum value of a
+  # range are optional, e.g. a job with no 'shortest_max_lifetime' and a
+  # 'longest_max_lifetime' of '3d' will handle every room with a retention policy
+  # which 'max_lifetime' is lower than or equal to three days.
+  #
+  # The rationale for this per-job configuration is that some rooms might have a
+  # retention policy with a low 'max_lifetime', where history needs to be purged
+  # of outdated messages on a more frequent basis than for the rest of the rooms
+  # (e.g. every 12h), but not want that purge to be performed by a job that's
+  # iterating over every room it knows, which could be heavy on the server.
+  #
+  # If any purge job is configured, it is strongly recommended to have at least
+  # a single job with neither 'shortest_max_lifetime' nor 'longest_max_lifetime'
+  # set, or one job without 'shortest_max_lifetime' and one job without
+  # 'longest_max_lifetime' set. Otherwise some rooms might be ignored, even if
+  # 'allowed_lifetime_min' and 'allowed_lifetime_max' are set, because capping a
+  # room's policy to these values is done after the policies are retrieved from
+  # Synapse's database (which is done using the range specified in a purge job's
+  # configuration).

+# 'txn_limit' gives the maximum number of transactions to run per connection
+# before reconnecting. Defaults to 0, which means no limit.
+#
+# 'args' gives options which are passed through to the database engine,
+# except for options starting 'cp_', which are used to configure the Twisted
+# connection pool. For a reference to valid arguments, see:

+#
+# Normally, the connection to the key server is validated via TLS certificates.
+# Additional security can be provided by configuring a `verify key`, which
+# will make synapse check that the response is signed by that key.
+#
+# This setting supercedes an older setting named `perspectives`. The old format
+# is still supported for backwards-compatibility, but it is deprecated.
+#
+# 'trusted_key_servers' defaults to matrix.org, but using it will generate a
+# warning on start-up. To suppress this warning, set

+#
+# Options for each entry in the list include:
+#
+#    server_name: the name of the server. required.
+#
+#    verify_keys: an optional map from key id to base64-encoded public key.
+#       If specified, we will check that the response is signed by at least
+#       one of the given keys.
+#
+#    accept_keys_insecurely: a boolean. Normally, if `verify_keys` is unset,
+#       and federation_verify_certificates is not `true`, synapse will refuse
+#       to start, because this would allow anyone who can spoof DNS responses
+#       to masquerade as the trusted key server. If you know what you are doing

+#       to the key server, you can set this to `true` to override this
+#       behaviour.

+## Single sign-on integration ##
+
+# List of OpenID Connect (OIDC) / OAuth 2.0 identity providers, for registration
+# and login.
+#
+# Options for each entry include:
+#
+#   idp_id: a unique identifier for this identity provider. Used internally
+#       by Synapse; should be a single word such as 'github'.
+#
+#       Note that, if this is changed, users authenticating via that provider
+#       will no longer be recognised as the same user!
+#
+#       (Use "oidc" here if you are migrating from an old "oidc_config"
+#       configuration.)
+#
+#   idp_name: A user-facing name for this identity provider, which is used to
+#       offer the user a choice of login mechanisms.
+#
+#   idp_icon: An optional icon for this identity provider, which is presented
+#       by clients and Synapse's own IdP picker page. If given, must be an
+#       MXC URI of the format mxc://<server-name>/<media-id>. (An easy way to
+#       obtain such an MXC URI is to upload an image to an (unencrypted) room
+#       and then copy the "url" from the source of the event.)
+#
+#   idp_brand: An optional brand for this identity provider, allowing clients
+#       to style the login flow according to the identity provider in question.
+#       See the spec for possible options here.
+#
+#   discover: set to 'false' to disable the use of the OIDC discovery mechanism
+#       to discover endpoints. Defaults to true.
+#
+#   issuer: Required. The OIDC issuer. Used to validate tokens and (if discovery
+#       is enabled) to discover the provider's endpoints.
+#
+#   client_id: Required. oauth2 client id to use.
+#
+#   client_secret: oauth2 client secret to use. May be omitted if
+#        client_secret_jwt_key is given, or if client_auth_method is 'none'.
+#
+#   client_secret_jwt_key: Alternative to client_secret: details of a key used
+#      to create a JSON Web Token to be used as an OAuth2 client secret. If
+#      given, must be a dictionary with the following properties:
+#
+#          key: a pem-encoded signing key. Must be a suitable key for the
+#              algorithm specified. Required unless 'key_file' is given.
+#
+#          key_file: the path to file containing a pem-encoded signing key file.
+#              Required unless 'key' is given.
+#
+#          jwt_header: a dictionary giving properties to include in the JWT
+#              header. Must include the key 'alg', giving the algorithm used to
+#              sign the JWT, such as "ES256", using the JWA identifiers in
+#              RFC7518.
+#
+#          jwt_payload: an optional dictionary giving properties to include in
+#              the JWT payload. Normally this should include an 'iss' key.
+#
+#   client_auth_method: auth method to use when exchanging the token. Valid
+#       values are 'client_secret_basic' (default), 'client_secret_post' and
+#       'none'.
+#
+#   scopes: list of scopes to request. This should normally include the "openid"
+#       scope. Defaults to ["openid"].
+#
+#   authorization_endpoint: the oauth2 authorization endpoint. Required if
+#       provider discovery is disabled.
+#
+#   token_endpoint: the oauth2 token endpoint. Required if provider discovery is
+#       disabled.
+#
+#   userinfo_endpoint: the OIDC userinfo endpoint. Required if discovery is
+#       disabled and the 'openid' scope is not requested.
+#
+#   jwks_uri: URI where to fetch the JWKS. Required if discovery is disabled and
+#       the 'openid' scope is used.
+#
+#   skip_verification: set to 'true' to skip metadata verification. Use this if
+#       you are connecting to a provider that is not OpenID Connect compliant.
+#       Defaults to false. Avoid this in production.
+#
+#   user_profile_method: Whether to fetch the user profile from the userinfo
+#       endpoint. Valid values are: 'auto' or 'userinfo_endpoint'.
+#
+#       Defaults to 'auto', which fetches the userinfo endpoint if 'openid' is
+#       included in 'scopes'. Set to 'userinfo_endpoint' to always fetch the
+#       userinfo endpoint.
+#
+#   allow_existing_users: set to 'true' to allow a user logging in via OIDC to
+#       match a pre-existing account instead of failing. This could be used if
+#       switching from password logins to OIDC. Defaults to false.
+#
+#   user_mapping_provider: Configuration for how attributes returned from a OIDC
+#       provider are mapped onto a matrix user. This setting has the following
+#       sub-properties:
+#
+#       module: The class name of a custom mapping module. Default is
+#           'synapse.handlers.oidc.JinjaOidcMappingProvider'.
+#           See https://matrix-org.github.io/synapse/latest/sso_mapping_providers.html#openid-mapping-providers
+#           for information on implementing a custom mapping provider.
+#
+#       config: Configuration for the mapping provider module. This section will
+#           be passed as a Python dictionary to the user mapping provider
+#           module's `parse_config` method.
+#
+#           For the default provider, the following settings are available:
+#
+#             subject_claim: name of the claim containing a unique identifier
+#                 for the user. Defaults to 'sub', which OpenID Connect
+#                 compliant providers should provide.
+#
+#             localpart_template: Jinja2 template for the localpart of the MXID.
+#                 If this is not set, the user will be prompted to choose their
+#                 own username (see 'sso_auth_account_details.html' in the 'sso'
+#                 section of this file).
+#
+#             display_name_template: Jinja2 template for the display name to set
+#                 on first login. If unset, no displayname will be set.
+#
+#             email_template: Jinja2 template for the email address of the user.
+#                 If unset, no email address will be added to the account.
+#
+#             extra_attributes: a map of Jinja2 templates for extra attributes
+#                 to send back to the client during login.
+#                 Note that these are non-standard and clients will ignore them
+#                 without modifications.
+#
+#           When rendering, the Jinja2 templates are given a 'user' variable,
+#           which is set to the claims returned by the UserInfo Endpoint and/or
+#           in the ID Token.
+#
+#   It is possible to configure Synapse to only allow logins if certain attributes
+#   match particular values in the OIDC userinfo. The requirements can be listed under
+#   `attribute_requirements` as shown below. All of the listed attributes must
+#   match for the login to be permitted. Additional attributes can be added to
+#   userinfo by expanding the `scopes` section of the OIDC config to retrieve
+#   additional information from the OIDC provider.
+#
+#   If the OIDC claim is a list, then the attribute must match any value in the list.
+#   Otherwise, it must exactly match the value of the claim. Using the example
+#   below, the `family_name` claim MUST be "Stephensson", but the `groups`
+#   claim MUST contain "admin".
+#
+#   attribute_requirements:
+#     - attribute: family_name
+#       value: "Stephensson"
+#     - attribute: groups
+#       value: "admin"
+#
+# See https://matrix-org.github.io/synapse/latest/openid.html
+# for information on how to configure these options.
+#
+# For backwards compatibility, it is also possible to configure a single OIDC
+# provider via an 'oidc_config' setting. This is now deprecated and admins are
+# advised to migrate to the 'oidc_providers' format. (When doing that migration,

+If you're using the horrendous `compose.keycloak2.yml` (as creator of this
+horrible hack, I am allowed to call it horrendous ;)), you will need to
+re-check the new ~/.abra/recipes/matrix-synapse/.env.sample, there are some new
+default env vars which you'll have to add in (e.g. KEYCLOAK2_ID=...).
+
+You'll also need to add `KEYCLOAK_ID=keycloak` if using `compose.keycloak.yml`,
+it isn't vendored any more.

+WARNING: There are a lot of config breaking changes in this one, watch out!
+
+* KEYCLOAK2* env vars have gone away, they were experimental.
+
+* TELEGRAM_BRIDGE_ADMIN* is replaced by TELEGRAM_BRIDGE_PERMISSIONS.
+
+* SIGNAL_BRIDGE_ADMIN* is replaced by SIGNAL_BRIDGE_PERMISSIONS.
+
+* The homeserver config has been trimmed, see coop-cloud/matrix-synapse#33 for more.
+
+* Bridge logging is only ERROR level now to minimise leaking plaintext.
+
+* It is possible to use SSO & federation env vars in combination now.
+
+* Media retention is now configurable with #MEDIA_RETENTION_* env vars.
