-HevSocks5Server is a simple, lightweight socks5 server for Unix.
+HoodySocks5Server (C++) is a simple, lightweight, high-performance SOCKS5 server for Unix, initially based on `HevSocks5Server`, improved by the developer (hev) himself as well as internally.
 
-**Features**
+**Available Features**
 * IPv4/IPv6. (dual stack)
 * Standard `CONNECT` command.
 * Standard `UDP ASSOCIATE` command.
 * Extended `FWD UDP` command. (UDP in TCP)
+* Multi-Threaded
 * Multiple username/password authentication.
-
+* Fake-security for non-auth mode for Hoody chnet
+* SuperProxy mode - Multiple bind addresses
+* Limit the number of concurrent connections per username/password
+* Hot reload credentials
+* Hot reload bind address
+
+**Upcoming Features**
+* Multiple listen address
+* Dynamic routing (multiple set of bind-address) based on socket endpoint (DNS/IP)
+* Benchmarking tool
+* IP Block
+* Built-in encryption system, compatible with Hoody signatures
+* Automatic worker threads scaling
+  
 ## How to Build
 
-**Unix**:
 ```bash
-git clone --recursive https://github.com/heiher/hev-socks5-server
-cd hev-socks5-server
-make
+# sudo apt-get install libssl-dev -y
+git clone --recursive https://github.com/Hoody-Network/HoodySocks5Server/
+cd HoodySocks5Server
+make -j
 
 # statically link
 make ENABLE_STATIC=1
 ```
 
-**Android**:
-```bash
-mkdir hev-socks5-server
-cd hev-socks5-server
-git clone --recursive https://github.com/heiher/hev-socks5-server jni
-cd jni
-ndk-build
-```
 
 ## How to Use

+### Config with bind-address hardcoded in Yaml file (NO Hot Reload)
+
+```yaml
+main:
+  # Worker threads
+  workers: 4

+  # Domain address type (ipv4|ipv6|unspec)
+  domain-address-type: ipv4
+
+#auth:
+#  file: conf/auth.txt
+#  username:
+#  password:
+
+```
+
 ### Authentication file
 
 ```
 <USERNAME> <SPACE> <PASSWORD> <SPACE> <LIMIT> <LF>
 ```
 
+### SuperProxy mode
+
+When multiple bind-address are available, it will pick a random one for each socket created (UDP supported too), this is because TLS handshakes often break when changing IP during negociation, so we keep the same Exit IP (bind-address) for that socket. 
+
+
 ### Run
 
 ```bash
-bin/hev-socks5-server conf/main.yml
+bin/hoody-socks5-server conf/main.yml
 ```
 
+### Limit concurrent connections per username
+
+This feature is to be used carefully, browsers/apps often establish 4-5 connections to the same SOCKS5 server, in authentication file, specifiy <LIMIT> after the password.
+
+`testlogin testpassword 10` # Will limit to 10 concurrent connections for this user.
+
+
 ### Live updating authentication file
 
 Send signal `SIGUSR1` to socks5 server process after the authentication file is updated.
 
 ```bash
-killall -SIGUSR1 hev-socks5-server
+killall -SIGUSR1 hoody-socks5-server
 ```
