-**TOPP-RA** is a library for computing the time-optimal path

-constraints.  In general, given the inputs:
 
-1. a geometric path `p(s)`, `s` in `[0, s_end]` ;
+Overview
+-----------
+
+
+TOPP-RA is a library for computing path parametrizations for geometric
+paths subject to certain forms of kinematic and dynamic constraints
+Simply speaking given
+
+1. a smooth geometric path :math:`p(s), s \in [0, s_{end}]` ;
 2. a list of constraints on joint velocity, joint accelerations, tool
    Cartesian velocity, et cetera.
 
-**TOPP-RA** returns the time-optimal path parameterization: `s_dot
-(s)`, from which the fastest trajectory `q(t)` that satisfies the
-given constraints can be found. All of this is done in a few
-milliseconds.
-
-Features
----------
+TOPP-RA can produce the time-optimal path parameterization
+:math:`s_{dot} (s)`, from which the fastest trajectory `q(t)` that
+satisfies the given constraints can be found. All of this is done in a
+few milliseconds.  There are some additional features that make it
+easier to generate high-quality motions for robots:
 
 1. Return the time-optimal parametrization or a parametrization with
    specified duration subject to constraints.
 2. Able to handle multiple constraint types:
-  1. joint torque, velocity and acceleration bounds;
-  2. *robust* joint torque, velocity and acceleration bounds;
-  3. Cartesian acceleration bounds;
-  4. contact stability for legged robots.
 3. Automatic grid-points selection.
 
-Applications
-------------
-
-**(Feb, 2019)** TOPP-RA was used to plan *critically fast*
-motions for robots doing bin picking with suction cup. Here
-*critically fast* motions are those that are fastest possible given
-the limited suction power and object weight. See the video below for
-more detail!
