 #### How do I adapt my running Prosody config to use this instead?
 
-Add these to modules_enabled:
+You have 2 options here, use xmpp-proxy as only a reverse proxy, or as both reverse and outgoing proxy, I'll cover both:
+
+###### Reverse proxy and outgoing proxy
+
+In this mode both prosody doesn't need to do any TLS at all, so it needs no certs. xmpp-proxy need proper TLS
+certificates, move prosody's TLS key to `/etc/xmpp-proxy/le.key` and TLS cert to `/etc/xmpp-proxy/fullchain.cer`, and
+use the provided `xmpp-proxy.toml` configuration as-is.
+
+Edit `/etc/prosody/prosody.cfg.lua`, Add these to modules_enabled:
 ```
-"secure_interfaces";
 "net_proxy";
+"s2s_outgoing_proxy";
+```
+Until prosody-modules is updated, use my new module [mod_s2s_outgoing_proxy.lua](https://www.moparisthebest.com/mod_s2s_outgoing_proxy.lua).
+
+Add this config:
+```
+-- only need to listen on localhost
+interfaces = { "127.0.0.1" }
+
+-- we don't need prosody doing any encryption, xmpp-proxy does this now
+-- these are likely set to true somewhere in your file, find them, make them false
+-- you can also remove all certificates from your config
+s2s_require_encryption = false
+s2s_secure_auth = false
+c2s_require_encryption = false
+allow_unencrypted_plain_auth = true
+
+-- xmpp-proxy outgoing is listening on this port, make all outgoing s2s connections directly to here
+s2s_outgoing_proxy = { "127.0.0.1", 15270 }
+
+-- handle PROXY protocol on these ports
+proxy_port_mappings = {
+    [15222] = "c2s",
+    [15269] = "s2s"
+}
+
+-- don't listen on any normal c2s/s2s ports (xmpp-proxy listens on these now)
+-- you might need to comment these out further down in your config file if you set them
+c2s_ports = {}
+legacy_ssl_ports = {}
+-- you MUST have at least one s2s_ports defined if you want outgoing S2S to work, don't ask.. 
+s2s_ports = {15268}
+```
+
+###### Reverse proxy only, prosody makes outgoing connections directly itself
+
+In this mode both prosody and xmpp-proxy need proper TLS certificates, copy prosody's TLS key to `/etc/xmpp-proxy/le.key`
+and TLS cert to `/etc/xmpp-proxy/fullchain.cer`, and use the provided `xmpp-proxy.toml` configuration as-is.
+
+Edit `/etc/prosody/prosody.cfg.lua`, Add these to modules_enabled:
+```
+"net_proxy";
+"secure_interfaces";
 ```
 Until prosody-modules is updated, use my patched version of [mod_secure_interfaces.lua](https://www.moparisthebest.com/mod_secure_interfaces.lua)
 which also works for s2s.

 ```

+#### Customize the build
-`xmpp-proxy.toml` configuration as-is.
+
+If you are a grumpy power user who wants to build xmpp-proxy with exactly the features you want, nothing less, nothing
+more, this section is for you!
+
+xmpp-proxy has multiple compile-time features, some of which are required, they are grouped as such:
+
+choose between 1-4 directions:
+  1. `c2s-incoming` - enables a server to accept incoming c2s connections
+  2. `c2s-outgoing` - enables a client to make outgoing c2s connections
+  3. `s2s-incoming` - enables a server to accept incoming s2s connections
+  4. `s2s-outgoing` - enables a server to make outgoing s2s connections
+
+choose between 1-4 transport protocols:
+  1. `tls` - enables STARTTLS/TLS support
+  2. `quic` - enables QUIC support
+  3. `websocket` - enables WebSocket support, also enables TLS incoming support if the appropriate directions are enabled
+  4. `webtransport` - enables WebTransport support, also enables QUIC
+
+choose exactly 1 of these methods to get trusted CA roots, not needed if only `c2s-incoming` is enabled:
+  1. `tls-ca-roots-native` - reads CA roots from operating system
+  2. `tls-ca-roots-bundled` - bundles CA roots into the binary from the `webpki-roots` project
+
+choose any of these optional features:
+  1. `logging` - enables configurable logging
+
+So to build only supporting reverse proxy STARTTLS/TLS, no QUIC, run: `cargo build --release --no-default-features --features c2s-incoming,s2s-incoming,tls`
+To build a reverse proxy only, but supporting all of STARTTLS/TLS/QUIC, run: `cargo build --release --no-default-features --features c2s-incoming,s2s-incoming,tls,quic`
+
+#### Development
+
+1. `check-all-features.sh` is used to check compilation with all supported feature permutations
+2. `integration/test.sh` uses [Rootless podman](https://wiki.archlinux.org/title/Podman#Rootless_Podman) to run many tests
+    through xmpp-proxy on a real network with real dns, web, and xmpp servers, all of these should pass before pushing commits,
+    and write new tests to cover new functionality.
+3. To submit code changes submit a PR on [github](https://github.com/moparisthebest/xmpp-proxy) or
+   [code.moparisthebest.com](https://code.moparisthebest.com/moparisthebest/xmpp-proxy) or send me a patch via email,
+   XMPP, fediverse, or carrier pigeon.

+-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
+

+certificates = "certsno"
+
+-- HTTPS currently only supports a single certificate, specify it here:
+--https_certificate = "/etc/prosody/certs/localhost.crt"
+
+----------- Virtual hosts -----------
+-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
+-- Settings under each VirtualHost entry apply *only* to that host.
+
+VirtualHost "one.example.org"
+
+VirtualHost "two.example.org"
+
+--VirtualHost "example.com"
+--	certificate = "/path/to/example.crt"
+
+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:
+--Component "conference.example.com" "muc"
+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info
+-- see: https://prosody.im/doc/components#adding_an_external_component

+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:

+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info

+
+-- Certificates
+-- Every virtual host and component needs a certificate so that clients and
+-- servers can securely verify its identity. Prosody will automatically load
+-- certificates/keys from the directory specified here.
+-- For more information, including how to use 'prosodyctl' to auto-import certificates
+-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
+
+-- Location of directory to find certificates in (relative to main config file):
+certificates = "certs"
+
+-- HTTPS currently only supports a single certificate, specify it here:
+--https_certificate = "/etc/prosody/certs/localhost.crt"
+
+----------- Virtual hosts -----------
+-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
+-- Settings under each VirtualHost entry apply *only* to that host.
+
+VirtualHost "one.example.org"
+
+VirtualHost "two.example.org"
+
+--VirtualHost "example.com"
+--	certificate = "/path/to/example.crt"
+
+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:
+--Component "conference.example.com" "muc"
+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info
+-- see: https://prosody.im/doc/components#adding_an_external_component

+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:
+--Component "conference.example.com" "muc"
+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info

+
+-- Certificates
+-- Every virtual host and component needs a certificate so that clients and
+-- servers can securely verify its identity. Prosody will automatically load
+-- certificates/keys from the directory specified here.
+-- For more information, including how to use 'prosodyctl' to auto-import certificates
+-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
+
+-- Location of directory to find certificates in (relative to main config file):
+certificates = "certs"
+
+-- HTTPS currently only supports a single certificate, specify it here:
+--https_certificate = "/etc/prosody/certs/localhost.crt"
+
+----------- Virtual hosts -----------
+-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
+-- Settings under each VirtualHost entry apply *only* to that host.
+
+VirtualHost "one.example.org"
+
+VirtualHost "two.example.org"
+

+
+-- Certificates
+-- Every virtual host and component needs a certificate so that clients and
+-- servers can securely verify its identity. Prosody will automatically load
+-- certificates/keys from the directory specified here.
+-- For more information, including how to use 'prosodyctl' to auto-import certificates
+-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
+

+certificates = "certs"
+
+-- HTTPS currently only supports a single certificate, specify it here:
+--https_certificate = "/etc/prosody/certs/localhost.crt"
+
+----------- Virtual hosts -----------
+-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
+-- Settings under each VirtualHost entry apply *only* to that host.
+
+VirtualHost "one.example.org"
+
+VirtualHost "two.example.org"
+
+--VirtualHost "example.com"
+--	certificate = "/path/to/example.crt"
+
+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:
+--Component "conference.example.com" "muc"
+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info
+-- see: https://prosody.im/doc/components#adding_an_external_component
+--
+--Component "gateway.example.com"
+--	component_secret = "password"

+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:

+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)

+
+-- Certificates
+-- Every virtual host and component needs a certificate so that clients and
+-- servers can securely verify its identity. Prosody will automatically load
+-- certificates/keys from the directory specified here.
+-- For more information, including how to use 'prosodyctl' to auto-import certificates
+-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
+
+-- Location of directory to find certificates in (relative to main config file):
+certificates = "certs"
+
+-- HTTPS currently only supports a single certificate, specify it here:
+--https_certificate = "/etc/prosody/certs/localhost.crt"
+
+----------- Virtual hosts -----------
+-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
+-- Settings under each VirtualHost entry apply *only* to that host.
+
+VirtualHost "two.example.org"
+
+--VirtualHost "example.com"
+--	certificate = "/path/to/example.crt"
+
+------ Components ------
+-- You can specify components to add hosts that provide special services,
+-- like multi-user conferences, and transports.
+-- For more information on components, see https://prosody.im/doc/components
+
+---Set up a MUC (multi-user chat) room server on conference.example.com:
+--Component "conference.example.com" "muc"
+--- Store MUC messages in an archive and allow users to access it
+--modules_enabled = { "muc_mam" }
+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/
+-- transports to other networks like ICQ, MSN and Yahoo. For more info
+-- see: https://prosody.im/doc/components#adding_an_external_component
+--
+--Component "gateway.example.com"
