+Building on iOS
+===================
+
+How to build i2pd for iOS 9 and iOS Simulator 386/x64
+
+Prerequisites
+--------------
+
+XCode7+, cmake 3.2+
+
+Dependencies
+--------------
+- precompiled openssl
+- precompiled boost with modules `filesystem`, `program_options`, `date_time` and `system`
+- ios-cmake toolchain from https://github.com/vovasty/ios-cmake.git
+
+Building
+------------------------
+Assume you have folder structure
+
+```
+lib
+	libboost_date_time.a
+	libboost_filesystem.a

+	libboost_system.a
+	libboost.a
+	libcrypto.a
+	libssl.a
+include
+	boost
+	openssl
+ios-cmake
+i2pd
+```
+
+
+```bash
+mkdir -p build/simulator/lib build/ios/lib include/i2pd
+
+pushd build/simulator && \
+cmake   -DIOS_PLATFORM=SIMULATOR \
+        -DPATCH=/usr/bin/patch \

+
+libtool -static -o lib/libi2pdclient.a build/*/libi2pdclient.a
+libtool -static -o lib/libi2pd.a build/*/libi2pd.a
+
+cp i2pd/*.h include/i2pd
+```
+
+Include into project
+---------------------------
+1. add all libraries in `lib` folder to `Project linked frameworks`.
+2. add `libc++` and `libz` libraries from system libraries to `Project linked frameworks`.
+3. add path to i2p headers to your `Headers search paths`
+
+Alternatively you may use swift wrapper https://github.com/vovasty/SwiftyI2P.git

+Usage and tutorials
+===================
+
+
+i2pd can be used for:
+
+* [anonymous websites](#browsing-and-hosting-websites)
+* [anonymous chats](#using-and-hosting-chat-servers)
+* [anonymous file sharing](#file-sharing)
+
+and many more.
+
+## Browsing and hosting websites
+
+### Browse anonymous websites
+
+To browse anonymous websites inside Invisible Internet, configure your web browser to use HTTP proxy 127.0.0.1:4444 (available by default in i2pd).
+
+In Firefox: Preferences -> Advanced -> Network tab -> Connection Settings -> choose Manual proxy configuration, Enter HTTP proxy 127.0.0.1, Port 4444
+
+In Chromium: run chromium executable with key
+
+    chromium --proxy-server="http://127.0.0.1:4444"
+
+Note that if you wish to stay anonymous too you'll need to tune your browser for better privacy. Do your own research, [can start here](http://www.howtogeek.com/102032/how-to-optimize-mozilla-firefox-for-maximum-privacy/).
+
+Big list of Invisible Internet websites can be found at [identiguy.i2p](http://identiguy.i2p).
+
+### Host anonymous website
+
+
+If you wish to run your own website in Invisible Internet, follow those steps:
+
+1) Run your webserver and find out which host:port it uses (for example, 127.0.0.1:8080).
+
+2) Configure i2pd to create HTTP server tunnel. Put in your ~/.i2pd/tunnels.conf file:
+
+    [anon-website]
+    type = http
+    host = 127.0.0.1
+    port = 8080
+    keys = anon-website.dat
+
+3) Restart i2pd.
+
+4) Find b32 destination of your website.
+
+Go to webconsole -> [I2P tunnels page](http://127.0.0.1:7070/?page=i2p_tunnels). Look for Sever tunnels and you will see address like \<long random string\>.b32.i2p next to anon-website.
+
+Website is now available in Invisible Internet by visiting this address.
+
+5) (Optional) Register short and rememberable .i2p domain on [inr.i2p](http://inr.i2p).
+
+
+## Using and hosting chat servers
+
+### Running anonymous IRC server
+
+1) Run your IRC server software and find out which host:port it uses (for example, 127.0.0.1:5555).
+
+For small private IRC servers you can use [miniircd](https://github.com/jrosdahl/miniircd), for large public networks [UnreadIRCd](https://www.unrealircd.org/).
+
+2) Configure i2pd to create IRC server tunnel.
+
+Simplest case, if your server does not support WebIRC, add this to ~/.i2pd/tunnels.conf:
+
+    [anon-chatserver]
+    type = irc
+    host = 127.0.0.1     
+    port = 5555
+    keys = chatserver-key.dat
+
+And that is it.
+
+Alternatively, if your IRC server supports WebIRC, for example, UnreadIRCd, put this into UnrealIRCd config:
+
+    webirc {
+        mask 127.0.0.1;
+        password your_password;
+    };
+
+Also change line:
+
+    modes-on-connect "+ixw";
+
+to
+
+    modes-on-connect "+iw";
+
+And this in ~/.i2pd/tunnels.conf:
+
+    [anon-chatserver]
+    type = irc
+    host = 127.0.0.1
+    port = 5555
+    keys = chatserver-key.dat
+    webircpassword = your_password
+
+3) Restart i2pd.
+
+4) Find b32 destination of your anonymous IRC server.
+
+Go to webconsole -> [I2P tunnels page](http://127.0.0.1:7070/?page=i2p_tunnels). Look for Sever tunnels and you will see address like \<long random string\>.b32.i2p next to anon-chatserver.
+
+Clients will use this address to connect to your server anonymously.
+
+### Connect to anonymous IRC server
+
+To connect to IRC server at *walker.i2p*, add this to ~/.i2pd/tunnels.conf:
+
+    [IRC2]
+    type = client
+    address = 127.0.0.1
+    port = 6669
+    destination = walker.i2p
+    #keys = walker-keys.dat
+
+Restart i2pd, then connect to irc://127.0.0.1:6669 with your IRC client.
+
+## File sharing
+
+You can share and download torrents with [Transmission-I2P](https://github.com/l-n-s/transmission-i2p).
+
+Alternative torrent-clients are [Robert](http://en.wikipedia.org/wiki/Robert_%28P2P_Software%29) and [Vuze](https://en.wikipedia.org/wiki/Vuze).
+
+Robert uses BOB protocol, i2pd must be run with parameter --bob.enabled=true.
+
+Vuze uses I2CP protocol, i2pd must be run with parameter --i2cp.enabled=true.
