+## Telegabber: like Zhabogram, but in Go! ##
+
+Now it's native, more asynchronous, and does not require to mess your server up with a monstrous third-party interpreter.
+
+The configuration file is compatible with Zhabogram 2.0, so you can easily copy your existing `config.yml`.
+
+### Build ###
+
+Prerequisites: Go links the binary against the `glibc` version present in the system where the build process happens, so it should be less or equal to the version of `glibc` in the system where Telegabber will run.
+
+* Build TDLib according to [TDLib build instructions](https://tdlib.github.io/td/build.html).
+* Install Go (tested with 1.13, but may work with earlier versions too).
+* Open the source dir in a new shell (to make sure that `$GOPATH` works) and run `make`. Dependencies will be installed automatically.
+
+After a successful build, you get a single binary to deploy on your server.
+
+### Installation ###
+
+First of all, you need to create component listener on your Jabber server. 
+For example, for ejabberd in **/etc/ejabberd/ejabberd.yml**:
+
+```
+listen:  
+  -  
+    port: 8888  
+    module: ejabberd_service  
+    access: all  
+    shaper_rule: fast  
+    ip: "127.0.0.1"  
+    service_check_from: false  
+    hosts:  
+        "tlgrm.localhost":  
+            password: "secret"
+```
+
+
+Next, rename **config.yml.example** to **config.yml** and edit **xmpp** section to match your component listener:
+
+
+```
+:xmpp:
+	db 'users.db'  
+	jid: 'tlgrm.localhost'  
+	host: 'localhost'  
+	port: 8888  
+	secret: 'secret'  
+	loglevel: :warn   
+```
+
+### Configuration ###
+
+It is good idea to obtain Telegram API ID from [**https://my.telegram.org**](https://my.telegram.org) to remove demo key requests limit, and then edit in **config.yml**:
+
+```
+:telegram:
+    :tdlib:
+        :lib_path: 'lib/'
+        :client:
+            :api_id: '845316' # telegram API ID (my.telegram.org) #
+            :api_hash: '27fe5224bc822bf3a45e015b4f9dfdb7' # telegram API HASH (my.telegram.org) #
+    ...
+```
+
+### How to receive files from Telegram ###
+
+First of all, you need to set up web server that will serve some directory in your filesystem.
+Example nginx config: 
+
+```
+server {
+	listen 80;
+	server_name tlgrm.localhost;
+	location /content {
+		alias /var/zhabogram;
+	}
+}
+```
+
+You need to set `:content: → :path: and :link:` **config.yml**.  
+  
+Set `:path:` according to location (for our example it will be `/var/zhabogram/content`).  
+Set `:link:` according to server_name (for our example it will be `http://tlgrm.localhost`)  
+
+
+### How to send files to Telegram chats ###
+
+You need to setup `mod_http_upload` for your XMPP server.  
+For example, for ejabberd in **/etc/ejabberd/ejabberd.yml**
+
+```
+modules:
+  mod_http_upload:
+    docroot: "/var/ejabberd/upload" # this must be a valid path, user ownership and SELinux flags must be set accordingly
+    put_url: "https://xmpp.localhost:5443/upload/@HOST@"
+    get_url: "https://xmppfiles.localhost/upload/@HOST@"
+    access: local
+    max_size: 500000000 #500 MByte
+    thumbnail: false
+    file_mode: "0644"
+    dir_mode: "0744"
+```
+
+Then you need to setup nginx proxy that will serve `get_url` path, because Telegram will not handle URLs with non-default http(s) ports.  
+Example nginx config:  
+
+/```
+server {
+	listen 80;
+	listen 443 ssl;
+
+	server_name xmppfiles.localhost;
+
+        # SSL settigns #
+        keepalive_timeout   60;
+        ssl_certificate      /etc/ssl/domain.crt;
+        ssl_certificate_key  /etc/ssl/domain.key;
+        ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
+        ssl_ciphers  "RC4:HIGH:!aNULL:!MD5:!kEDH";
+        add_header Strict-Transport-Security 'max-age=604800';
+
+        location / {
+            proxy_pass https://xmpp.localhost:5443;
+        }	
+
+}
+
+```
+
+Finally, update `:upload:` in your config.yml to match `server_name` in nginx config.
