 # Telecommander
 
-The experimental full-featured command line client for Telegram is in development.
+The experimental full-featured curses-like command line client for Telegram is in heavy development, but also already usable!
 
 It uses [enricostara](http://github.com/enricostara)'s [telegram.link](http://github.com/enricostara/telegram.link) to connect to Telegram and [chjj](http://github.com/chjj)'s [blessed](http://github.com/chjj/blessed) for the UI.
 
-At the moment you can use Telecommander to register or login into telegram. Yep, that's it for now, but stay tuned!
+### What it can and can't do
+
+As of __now__, __Telecommander lets you__:
+
+- Sign up for telegram
+    - not sure it totally works, not really the priority for now
+- Sign in with a code sent via SMS or telegram
+- Keep signed in until you delete the files stored in `~/.config/telecommander` or the session expires
+- Do everything __completely in the terminal, even via ssh__
+- Navigate your contact and chat list __using the mouse__
+- Do basic usage with __no complicated commands to learn__
+- Chat with your friends!
+- Chat in groups!
+
+For version _0.1.0_ (Almost done!):
+
+- Notifications
+- Online Status viewing and management
+- Automatic marking of messages as read
+
+What's missing (for future versions up to 1.0)
+
+- Scrolling back to view old messages
+- Create, modify, manage groups
+- Secret chats
+- Manage your contacts
+- Manage your profile
+- Easy bot interaction
+- Send and download files, audio messages, images
+- Open links
+- Emoticons (they show up as question marks)
+- Sign out (without having to manually delete files)
+- Delete account
+- Reply to and Forward message support
+- Do everything (except writing, duh) with the mouse!
+- Cool interface (it's already ok, just not as cool as I want it to be)
+- Optimization and automatic datacenter switching
+
+What could be available after 1.0:
+
+- plugin API
+- Telecommander as a library
+- Parsable output mode
+- More cool stuff!
+
+A lot of features depend on [telegram.link](http://telegram.link)'s still missing implementation sadly, but it'll come around eventually.
+
+### Hacking
+
+To start Telecommander from source you'll need:
+
+- __npm__, most of the time packaged with node
+- __python__ version 2.x (probably need a recent one)
+- __git__ to download the source
+
+Let's set it up:
+
+```sh
+$ git clone https://github.com/fazo96/Telecommander.git
+$ cd Telecommander
+
+# If you just need to test it
+
+$ npm install
+$ ./telecommander.js
+
+# If you want to install it
+
+# Try with sudo if it doesn't work
+$ npm install -g .
+$ telecommander
+
+# If npm install fails because of something about "gyp"
+# it means your python points to python 3
+# either swap it with python 2 or if you're on arch linux
+# and/or your python 2 executable is "python2" just run this:
+
+$ PYTHON=python2 npm install [-g .] 
+```
+
+__PLEASE READ:__ if you fork the project and want to create a custom version of
+Telecommander please change the app.id and app.hash values in the source
+(should be in the first 30 lines of code) to the ones you can get
+(for free) from http://my.telegram.org
