-AT Installation
----------------
-
-The AT code in this repository evolved from version 1.3 of the original code
-and is now maintained by the 'atcollab' collaboration, involving people from
-different research institutes.
-
-The latest release can be found [on Github](https://github.com/atcollab/at/releases).
-
-Requirements:
--------------
-AT is compatible with:
-- **Matlab** release >= R2016b (Matlab 9.1)
-- **Octave** >= 6.0
-
-Installation process:
----------------------
-
-1. Install git on your computer.
-
-2. Download the latest version of AT:
-    ```
-    $ git clone https://github.com/atcollab/at.git
-    ```
-
-3. Insert recursively the directories `at_installation/atmat` and
-`at_installation/atintegrators` in the Matlab path. This can be done by:
-    - Using the GUI:
-        Open the "Set Path" window, press "Add with subfolders", select
-        `at_installation/atmat`; repeat the operation for
-        `at_installation/atintegrators`.
-    - Using the `startup.m` file:
-        Insert a line `addpath(genpath(at_installation/atmat)` and a similar
-        one for atintegrators.
-    - Temporarily modifying the path by running:
-        ```
-        >> cd  at_installation/atmat
-        >> atpath
-        ```
-
-4. Compile all mexfunctions:
-    ```
-    >> atmexall
-    ```
-
-5. Update helpfiles:
-    ```
-    >> atupdateContents
-    ```
-    You can now use `athelp` to list all main functions.
-
-6. Update html doc - not yet documented.
-
-### Notes on Octave ###
-
-For the most part AT code works with [Octave](https://www.gnu.org/software/octave/).
-At least version 6 is required.
-
-In order to prepare octave environment you'll need to run `atoctave/bootstrap.m` function.
-It will install required Octave modules (Internet connection is needed), compile C sources and add
-paths.
-
-When in `at` folder, you may start an Octave CLI session with command:
-```bash
-> octave --eval 'cd atoctave;bootstrap;cd ..;' --persist
-```
-For GUI session, run command:
-```bash
-> octave --gui --eval 'cd atoctave;bootstrap;cd ..;' --persist
-```
-These commands will run `atoctave/bootstrap.m` for you.

-Installation
-------------
 
-See the `INSTALL.md` document.
+Accelerator Toolbox (AT) is a collection of tools to model storage rings and beam transport lines.
 
-Online documentation
---------------------
+With AT, it is possible to:
+
+- **create and manipulate accelerator lattice elements**,
+- **track particles through the lattice**, selecting the appropriate integrator to represent the physics
+- **compute accelerator parameters and beam properties**, generating new scripts or taking advantage of the existing ones
+
+AT is based on a 6-D modular tracking engine written in C/C++ for efficiency.
+Lattice manipulation and computation of accelerator physics parameters are provided
+by two interfaces:
+
+- a [Matlab interface](https://atcollab.github.io/at/m/index.html), available as a Matlab toolbox,
+- a [python interface](https://atcollab.github.io/at/p/index.html#), available as a python package.
+
+## Installation
+
+- For [Matlab](https://atcollab.github.io/at/m/Installation.html)
+- For [python](https://atcollab.github.io/at/p/howto/Installation.html)
