+## Setting up Xash3D FWGS in Qt Creator
+
+### Intro
+
+Most versions of Qt Creator support using `compile_commands.json` as a project
+file and Waf supports generating this file in a compliant format. In this
+tutorial we will leverage that features.
+
+The tutorial is written using Qt Creator 18.0, but I urge you to use whatever
+latest Qt Creator version is available, as it's often has important bug fixes.
+
+### Step 1. Configure the build.
+
+`compile_commands.json` file, as it can be guessed from it's name, contains
+every command used to invoke compiler during build. As the build process
+depends on the build configuration, we have to configure it first. I'm not
+going to get into details here, as basics of compiling Xash3D FWGS already
+explained in `README.md`, located in repository root.
+
+Save the configure step command somewhere, as it's going to be used later.
+
+### Step 2. Generate `compile_commands.json` file.
+
+Usually, this file is located in `build` directory after a successful build.
+However, it's also possible to generate it manually by running follow command:
+
+On *nix systems:
+
+```
+$ ./waf clangdb
+```
+
+Or on Windows:
+
+```
+> waf.bat clangdb
+```
+
+### Step 3. Load the project in Qt Creator.
+
+To do this, you need to be sure that `Compilation Databases` plugin is enabled.
+As it's considered experimental, it probably needs to be enabled manually. It
+can be done in `Help` -> `About Plugins...`. Locate it in `Build Systems`
+category, put the checkbox and press `OK`. The IDE will ask for restart, so do
+this.
+
+After IDE has been restarted, you can use `File` -> `Open File or Project...`.
+Navigate to Xash3D FWGS directory, then to `build` directory and select
+`compile_commands.json` file. If everything is done correctly, IDE will ask to
+set up the project. Press `Configure Project` button, as most options there are
+usually unapplicable to us.
+
+Next IDE will show project tree, however you might not see any files. This is
+happens as Qt Creator "thinks" our project root located in `build` directory.
+Thankfully it provides a way to override this. To fix it, click with right
+mouse button on the root of project tree (it's usually called something like
+`build [master]`) and select `Change Root Directory`. In opened window choose
+Xash3D FWGS repository root and press `OK`.
+
+### Step 4. Tell IDE how to build this project.
+
+Open `Projects` on the left menu and choose `Build Settings` tab. You should
+see an empty configuration for build and clean steps. Press on `Add Build Step`
+button and choose `Custom Process Step`.
+
+In created step you should see `Command`, `Arguments` and `Working Directory`.
+
+For the command, choose the Python executable. For arguments, use configure
+command for Waf from the first step. Working directory is usually set by IDE
+to `%{buildDir}`. You need to select the upper directory, where the `waf` is
+located. To save some time, it can be specified as `%{buildDir}/../`.
+
+Add another custom step, fill it with the same command and working directory.
+For arguments use `waf build`.
+
+Below you should see `Clean steps`. Create a clean step the same way, fill the
+arguments and working directory as usual, for arguments use `waf clean`.
+
+### Step 5. Tell IDE how to copy built binaries.
+
+Now select `Deploy Settings` tab. Press `Add Deploy Step` -> `Custom Process
+Step`. Again, same command and working directory. In arguments field type:
+`waf install --destdir="<here put where Xash binaries should be copied to>"`.
+
+### Step 6. Finally, set up Qt Creator to run the engine.
+
+Select the `Run Settings` tab. Below you might see familiar text fields:
+`Executable`, `Command line arguments` and `Working directory`.
+
+For working directory click on `Browse...` button and select the folder where
+Xash3D executable will be copied to, from previous step.
+
+For executable type `./xash3d` if you're on *nix or `xash3d.exe` if you're on
+Windows. The command line arguments are the same you use to run the engine. Can
+be empty as well, but I personally use `-dev 2 -log` for extra verbosity.
+
+### Outro
+
+At this moment, you should be able to press `Run` button, wait until build
+finishes and see running Xash3D FWGS. On Windows to use the debugger you might
+need the `CDB` debugger and appropriate `qtcreatorcdbext` binary for debugging
+32-bit applications and a separate for 64-bit, but that's left as an exercise
+for the reader and a potential improvement for this document.

+## Lightmapped water
+
+Xash3D FWGS supports lightmapped water, as an extension. It adds three new cvars and new worldspawn key values.
+
+### For level designers:
+
+If you're a level designer and intend to make your level to have lightmapped water, you can put these keyvalues to worldspawn entity description (always first entity in entities list):
+
+| Key                    | Value   | Description |
+| ---------------------- | ------- | ----------- |
+| `_litwater`            | integer | Set to any non-zero value to enable lightmapped water. Overrides `gl_litwater_force` cvar value. |
+| `_litwater_minlight`   | integer | Minimal lightmap value water surface will receive. Helps to avoid too dark areas when water isn't properly lit. If not set, defaults to zero. |
+| `_litwater_scale`      | float   | Scales up lightmap value for water surfaces. If not set, defaults to 1.0. |
+
+### For players:
+
+Some of the maps already have computed lightmap for water surfaces and sometimes water has been properly lit but the support hasn't been declared by the level designer.
+
+As a player, you can enable it in `Video options` menu or through console with `gl_litwater_force` cvar. There are also `gl_litwater_minlight` and `gl_litwater_scale` cvars that function similar to keys above. The default values has been set to `192` and `1.25` respectively to slightly avoid issues with maps that wasn't intended to have lightmapped water.

+# Steam API Broker Protocol Specification
+
+## Overview
+
+Due to proprietary nature of Steamworks SDK, it cannot be run on same amount
+of platforms supported by Xash3D FWGS, neither we can link library directly due to
+GNU GPLv3 license. 
+
+However, here comes the broker, by running it (in trusted
+network, preferrably) on a machine that has Steam client installed, the
+engine can communicate with it, acquiring needed information to log-in into
+Steam protected multiplayer servers.
+
+## Key Characteristics
+
+Broker uses a simple TCP-based binary protocol with the following properties:
+
+- Single active session per connection: once a session is activated, the broker will reject all other TCP connections until the session is terminated.
+- All messages follow a consistent structure with a header, length, and payload: this is called a "frame".
+- Stateful interactions: commands affect the session state, and certain commands are only valid in specific states.
+- Numeric parameters are encoded in little-endian format for compatibility with majority of platforms.
+---
+
+## Frame Format
+
+All communication uses a fixed frame structure:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 4 bytes | ASCII | Frame start signature |
+| Length | 2 bytes | uint16_t (LE) | Size of payload in bytes |
+| Payload | N bytes | Binary | Command string or response data |
+
+**Notes**:
+- Header must be exactly `SBRK` (`53 42 52 4B` in hexadecimal form)
+- Maximum frame size: soft limit is 4096 bytes, hard limit is 65535 bytes (due to uint16_t usage)
+
+---
+
+## Session Lifecycle
+
+```
+┌──────────────┐
+│     IDLE     │ ← Initial state, accepts new TCP connections
+└──────────────┘
+       │ sb_gamedir
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Session established, rejecting all of other TCP connections
+└──────────────┘
+       │ sb_connect
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Client getting auth ticket to connect to game server

+└──────────────┘
+       │ 
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Client shutting down game, terminating broker to reset Steam client state
+└──────────────┘
+       │ sb_terminate
+       ↓
+┌──────────────┐
+│  RESTARTING  │
+└──────────────┘
+```
+
+---
+
+## Commands
+
+All commands listed below are meant to be sent from client to broker as payload of a frame. The broker will parse the command string and respond accordingly.
+
+### Session activation
+
+Activates the session and signaling game startup.
+
+**Format**: `sb_gamedir <gamedir>`
+
+**Response**: None
+
+---
+
+### Authentication ticket request
+
+Requests authentication ticket for a game server.
+
+**Precondition**: Session must be active
+
+**Format**: `sb_connect <ip:port> <server_steamid> <secure> <challenge>`
+
+**Parameters**:
+
+| Name | Description |
+|------|------------------|
+| `<ip:port>` | Game server address (e.g., `127.0.0.1:27015`) |
+| `<server_steamid>` | Server SteamID |
+| `<secure>` | 0 = insecure, 1 = secure |
+| `<challenge>` | Random value for reply prevention |
+
+
+**Response Format**:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 11 bytes | string | `"sb_connect\n"` |
+| Challenge | 4 bytes | int32_t (LE) | Echo of challenge from request |
+| SteamID | 8 bytes | uint64_t (LE) | Client SteamID from configuration |
+| Size | 4 bytes | uint32_t (LE) | Length of ticket in bytes |
+| Ticket | N bytes | - | Authentication ticket data |
+
+---
+
+### Server disconnection announcement
+
+Notifies broker of disconnection from game server.
+
+**Precondition**: Session must be active
+
+**Format**: `sb_disconnect <ip:port> <challenge>`
+
+**Response**: None
+
+---
+
+### Session termination
+

+# XRCON Protocol Specification
+
+## Overview
+
+XRCON is a TCP-based remote console protocol implemented as a server within the engine. It provides an alternative to the legacy RCON (which operates over UDP as out-of-band packets). XRCON uses a framed binary protocol over a single persistent TCP connection, accepting at most one client at a time.
+
+Key characteristics:
+
+- Based on TCP (stream-oriented, reliable)
+- Default port is 27000
+- Maximum only one concurrent client
+- Binary framed protocol with a 12-byte header + variable-length payload
+
+
+
+## Configuration
+
+The XRCON server is controlled by two configuration variables, both restricted to privileged users:
+
+| Variable | Default | Description |
+|---|---|---|
+| `xrcon_enable` | `0` (disabled) | Master switch; when enabled, the server starts listening for connections |
+| `xrcon_address` | `127.0.0.1:27000` | Bind address and port; supports both IPv4 and IPv6. Changing this at runtime triggers a XRCON server restart (stop + rebind) |
+
+By default, XRCON binds only to localhost (`127.0.0.1`), providing a degree of access control. The server will not start listening until explicitly enabled.
+
+
+
+## Frame Format
+
+All XRCON messages are encapsulated in a framed binary format. Each frame consists of a fixed 12-byte header followed by a variable-length payload.
+
+### Header (12 bytes)
+
+| Offset | Size | Field | Description |
+|---|---|---|---|
+| 0 | 4 | Type | 4-character message type string (null-terminated, occupies 5 bytes in the structure but the 5th byte is padding) |
+| 4 | 4 | Version | Protocol version (32-bit unsigned integer, network byte order) |
+| 8 | 2 | Length | Total frame length in bytes, including the header (16-bit unsigned integer, network byte order) |
+| 10 | 2 | Handle | Handle or sequence number (16-bit unsigned integer, network byte order; currently always zero) |
+
+
+### Protocol Version
+
+The current protocol version is `0x000000D4` (212 decimal). The server also accepts `0x00D40000` for compatibility with certain third-party clients (e.g., CS2RemoteConsole).
+
+### Maximum Frame Size
+
+- Maximum payload per frame: 4096 bytes
+- Maximum total packet size (header + payload): approximately 4136 bytes
+- Receive buffer size: 4096 + 64 bytes
+- Transmit buffer size: 16384 bytes (4 × maximum frame size)
+
+### Byte Order
+
+Multi-byte integer fields (version, length, handle) are transmitted in **network byte order** (big-endian).
+
+
+
+## Message Types
+
+| Type | Direction | Description |
+|---|---|---|
+| `CMND` | Client → Server | Execute a console command |
+| `PRNT` | Server → Client | Console output / print message |
+| `CHAN` | Server → Client | Channel list (channel metadata) |
+| `AINF` | Server → Client | Application / server info |
+| `ADON` | Server → Client | Additional info / server name |
+
+### CMND — Client Command
+
+**Direction**: Client → Server
+
+Sent by the client to execute a console command on the server.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CMND"`, version, length, handle |
+| Payload | Variable | Raw command string (null-terminated) |
+
+The command string is injected into the engine's command buffer for execution. There is **no authentication** — any connected client may execute arbitrary commands.
+
+### PRNT — Server Print
+
+**Direction**: Server → Client
+
+Sent by the server to stream console output to the connected client.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"PRNT"`, version, length, handle |
+| Channel ID | 4 bytes | Channel identifier (unsigned 32-bit integer; always 0 for "Console") |
+| Padding | 20 bytes | Reserved (5 × 32-bit unsigned integers, all zero) |
+| Red | 1 byte | Red color component (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha / opacity component (always 255) |
+| Text | Variable | The console output text (up to 4096 bytes) |
+
+
+### CHAN — Channel List
+
+**Direction**: Server → Client
+
+Sent by the server during the initial handshake (and potentially later) to describe the available console output channels.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CHAN"`, version, length, handle |
+| Channel Count | 2 bytes | Number of channel records (unsigned 16-bit integer; always 1) |
+
+Each channel record (58 bytes):
+
+| Field | Size | Description |
+|---|---|---|
+| Channel ID | 4 bytes | Unique channel identifier (unsigned 32-bit integer; always 0) |
+| Unknown 1 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Unknown 2 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Default Verbosity | 4 bytes | Default verbosity level (unsigned 32-bit integer; always 5) |
+| Current Verbosity | 4 bytes | Current verbosity level (unsigned 32-bit integer; always 5) |
+| Red | 1 byte | Red color component for the channel (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha component (always 255) |
+| Name | 34 bytes | Channel name string, null-padded (always `"Console"`) |
+
+Total payload size for this frame: 2 + 58 = 60 bytes.
+
+### AINF — Application Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after a client connects, before `ADON` and `CHAN`.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"AINF"`, version, length, handle |
+| Payload | 77 bytes | All zeros (placeholder / reserved for structured application information) |
+
+This packet currently serves as a placeholder and contains no meaningful data. It may be extended in future versions to carry structured metadata about the server application.
+
+### ADON — Additional Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after `AINF` during the connection handshake.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"ADON"`, version, length, handle |
+| Unknown | 2 bytes | Reserved (unsigned 16-bit integer; always 0) |
+| Name Length | 2 bytes | Length of the name string (unsigned 16-bit integer) |

+## Security
+
+XRCON has **no built-in authentication or encryption**. There is no password validation or transport-layer security. Any client that can establish a TCP connection to the XRCON port has full command execution access to the engine console.
+
+The only security measures are:
+
+1. **Default localhost binding**: The server binds to `127.0.0.1` by default, accepting connections only from the local machine.
+2. **Disabled by default**: The `xrcon_enable` variable defaults to `0`, so the server does not listen unless explicitly enabled.
+3. **Privileged variables**: Both configuration variables are restricted to privileged users and cannot be modified through unprivileged console commands or external access.
+
+
+
+## Comparison with Legacy RCON
+
+| Feature | XRCON | Legacy RCON |
+|---|---|---|
+| Transport | TCP (stream) | UDP (datagram, out-of-band) |
+| Port | Configurable, default 27000 | Game port (default 27015) |
+| Framing | Binary frame header | Plain text over UDP |
+| Authentication | None | Password-based |
+| Max clients | 1 | Multiple |
+| Interaction format | Full console access | Request-response only for submitted command |
+| Supported environments | Client and server | Server only |

 # Support for GoldSrc network protocol
-This feature is still work-in-progress, but for now it's available for all users, and we appreciate any bug-reports and contributions around it.
-
 For connecting to GoldSrc-based servers, use this command:
 ```
 connect ip:port gs
 ```
 
-But keep in mind, there are requirement for server to be able to accept connections from Xash3D-based clients: it should use Reunion.
-Without this requirement, you will just get "Steam validation rejected" error on connecting.
+You need to use [Steam API broker](https://github.com/FWGS/steam-broker) and have purchased Half-Life 1 on your Steam account to be able to join GoldSrc servers.
 
-That is because proper authorization with Steam API is not implemented in engine yet (but we have plans on it).
+Broker will run on your PC and will be responsible for communicating with Steam client and obtaining auth tickets.
+Also, make sure to set that broker as current ticket generator using console or edit `config.cfg` file manually:
+```
+cl_ticket_generator steam
+```
 
-Also, we encountered that some GoldSrc-based servers are recognizing Xash3D clients as "fake clients" and banning/kicking them. Maybe this problem will be
+If you want to join GoldSrc servers from other device (Android/iOS or console), make sure to set proper broker IP address with `cl_steam_broker_addr` console variable. Default value assumed that broker is running on the same device as game client.
+
+By the way, we encountered that some GoldSrc-based servers are recognizing Xash3D clients as "fake clients" and banning/kicking them. Maybe this problem will be
 solved along with better compatibility with GoldSrc behavior, but may be not - we don't know logic behind this fake client checks.

+Xash3D FWGS currently supports four network protocols:
+* Version 49, introduced in Xash3D in around 2018.
+* Version 48, used in Xash3D FWGS 0.19 and earlier. Deprecated and to be removed in the future.
+* GoldSrc version 48, used in current GoldSource version.
+* Quake version 15, only used for demo playback for Quake Wrapper mod.
+
+On the server side, we only support Xash3D 49 protocol, but bugcomp `gsmrf` mode can convert GoldSrc 48 messages into Xash3D 49 on the fly, for some mods that directly write engine internal messages.
+
+In the following documents we will only cover version 49, as everything else is either not Xash3D specific or deprecated.

+Connectionless protocol defines four common message sources and destinations, they can be:
+* `S` for Server
+* `C` for Client
+* `M` for Master
+* `A` for Anything else
+
+All connectionless packets have `\xff\xff\xff\xff` (32-bit integer set to all ones) in it's header. Let's go through each of possible direction in this document.

+
+Possible requests and response formats:
+* Request ID `1` will make server respond with empty response string.

+
+Used to validate client's address to prevent faked/forged source IP addresses.
+
+* Header: `\xff\xff\xff\xff`
+* Request, in ASCII: `getchallenge steam`
+  - `steam` argument is optional and can be ignored by the server, as it's only kept for compatibility with similar GoldSrc 48 message.
+
+* Possible responses:
+  - `S2C_CHALLENGE`
+
+#### `C2S_CONNECT`
+
+Used to build a connection with the server.
+
+* Header: `\xff\xff\xff\xff`
+* Request, in ASCII: `connect <version> <challenge> "<protinfo>" "<userinfo>"`
+  - `version` must be 49, as text.
+  - `challenge` must be challenge value, as text.
+  - `protinfo` is a Quake info string, containing protocol extensions and other connection information.
+    - `uuid` is this client's unique ID (FWGS extension) hasheed with MD5.
+    - `qport` is random integer value from 1 to 65535, unique for this engine run.
+    - `ext` is an integer value OR'ed with requested protocol extensions. Currently only extension is `NET_EXT_SPLITSIZE` with the value of `1`, which tells server to split messages based on `cl_dlmax` value from `userinfo`. 
+  - `userinfo` contains initial user info, encoded as Quake info string.
+* Possible responses:
+  - `A2A_PRINT` followed by `S2C_REJECT`
+  - `S2C_ERRORMSG` (as FWGS extension) followed by `A2A_PRINT` and `S2C_REJECT`.
+  - `S2C_CONNECTION`
+
+### Server to Client
+
+#### `S2C_BANDWIDTHTEST`
+
+* Request: `testpacket<crc><blob>`
+  - `crc` is 32-bit CRC of `blob`
+  - `blob` random data
+* There is no required response to this message
+
+Total message size doesn't exceed request max size.
+
+#### `S2C_CHALLENGE`
+
+* Request, in ASCII: `challenge <value>`
+  - `value` is challenge value that client must include in it's response
+* Response: `C2S_CONNECT`
+
+#### `S2C_CONNECTION`
+
+* Request, in ASCII: `client_connect <protinfo>`
+  - `protinfo` is an optional Quake info string, contains following optional fields:
+     - `ext` is an integer value OR'ed with allowed protocol extension. Bit fields match requested in `ext` field in `C2S_CONNECT`
+     - `cheats` set to 1 if server allows cheats otherwise 0
+* Response: there is no out of band from the client but client will proceed to building netchan and switch client-server interaction to it.
+
+#### `S2C_ERRORMSG`
+
+Show client error message. Doesn't mean connection reject, only used for UI.
+
+* Request, in ASCII: `errormsg <message>`
+  - `message` contains error message
+* Response: none
+
+#### `S2C_REJECT`
+
+Client has been rejected in connection.

+# Static HTTP server list
+
+Replacement for the UDP `S2M_SCAN_REQUEST` / `M2A_SERVERSLIST` exchange
+described in [02-connectionless.md](02-connectionless.md). Read-only HTTP,
+no NAT punching, no filtering or pagination in the request.
+
+## URL
+
+`xashcomm.lst` carries a base URL per source:
+
+```
+masterstatic http://master.example.org/server-list
+```
+
+The engine appends `/v1/servers/<gamedir>` and `GET`s the result. For
+`gamedir = valve`:
+
+```
+GET http://master.example.org/server-list/v1/servers/valve
+```
+
+Trailing slashes on the base URL are stripped. Multiple `masterstatic`
+lines are allowed; results are merged.
+
+The request is bare: no body, no auth, no cookies, no compressed encodings.
+Only the standard `User-Agent` is set. `POST` / `PUT` / `DELETE` are not
+used; servers register out of band.
+
+## Response
+
+UTF-8 text, parsed line by line. Each line is tokenized with
+`COM_ParseFileSafe` (whitespace separates, `//` and `#` start line
+comments, `"..."` quotes a token). Blank lines and comment-only lines
+are ignored. One directive per line:
+
+* `ip <address>` — Xash3D server (protocol 49).
+* `gs <address>` — GoldSrc server (protocol 48).
+
+`<address>` is parsed by `NET_StringToAdr` (`1.2.3.4:27015`,
+`[2001:db8::1]:27015`, hostnames). Port defaults to `27015`. Lines
+starting with an unknown directive are skipped entirely, so new keywords
+with any number of operands can be added without breaking older clients.
+
+`Content-Type` is not inspected, `text/plain; charset=utf-8` expected.
+
+### Example
+
+```
+# diffusion servers
+ip 192.0.2.10:27015
+ip [2001:db8::1]:27015
+gs 198.51.100.5:27015
+```
+
+A file with zero records is valid and represents an empty list.
+
+### Versioning
+
+The `/v1/` segment is fixed in this revision. A future protocol revision
+adds a sibling `/v2/...` resource without breaking older clients.
+
+## Client behaviour
+
+Each `ip` / `gs` record from the response triggers a probe to the listed
+address, identical to a server discovered through the UDP master. DNS
+errors, non-200 responses, and malformed bodies are reported to the
+console.
+
+## Server behaviour
+
+Any static HTTP server works. A typical setup is a periodic job that
+probes a set of known addresses and writes `v1/servers/<gamedir>`.

 ### Building

 3) Install: `./waf install --destdir=/path/to/any/output/directory`.
 
 #### Android (Windows/Linux/macOS)
-You can just open the `android` folder in Android Studio and build from here, or use `gradlew` to build from command line.
+To build you should clone [SDL](https://github.com/libsdl-org/SDL) from `SDL2` branch and [HLSDK-portable](https://github.com/FWGS/hlsdk-portable) `mobile-hacks` branch repositories to 3rdparty folder, after that you should be able to open the project in Android Studio from `android` directory or manually call Gradle to build the APK.

+#### iOS/iPadOS (MacOS only)
+0) (optional) Examine which build options are available: `./waf --help`.
+1) Configure build: `./waf configure --ios --enable-bundled-deps --sdl2 (path/to/SDL2.framework)`, set `--ios-simulator` instead of `--ios` if you want to build for simulator.
+2) Compile `./waf build`.
+3) Navigate to `build` and copy your compiled SDL2.framework there, then add your game dylibs to `build/ios/libs/(gamedir)/(dlls/cl_dlls)`(You can also run `scripts/ios/buildhlsdk.sh` instead to automatically create an ipa with hlsdk dylibs)
+4) Run `scripts/ios/createipa.sh` to create an installable ipa
+
+### Running tests
+
+Tests are enabled with `--enable-tests` passed to `./waf configure` and can be run with `./waf --alltests`.
+
+This builds both standalone unit tests and a separate engine test binary (`xash3d_tests`) that embeds engine-level tests. The engine test binary requires no game assets.

+
+## Supported versions
+
+Because we don't have clear release cycle yet, support is only provided to the
+latest engine versions from `master` branch. You can use `host_ver` command in
+console to fetch detailed info about the engine build.
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in this project, it can be reported
+privately though `Security` tab on GitHub:
+https://github.com/FWGS/xash3d-fwgs/security
+
+Alternatively, you can report them publicly on the `Issues` tab:
+https://github.com/FWGS/xash3d-fwgs/issues
+
+In both cases, expect a reply within approximately a week.
