 # KMath
 The Kotlin MATHematics library is intended as a Kotlin-based analog to Python's `numpy` library. In contrast to `numpy` and `scipy` it is modular and has a lightweight core.
 
 ## Features
 
+Actual feature list is [here](doc/features.md)
+
 * **Algebra**
     * Algebraic structures like rings, spaces and field (**TODO** add example to wiki)
     * Basic linear algebra operations (sums, products, etc.), backed by the `Space` API.
     * Complex numbers backed by the `Field` API (meaning that they will be usable in any structure like vectors and N-dimensional arrays).
-    * [In progress] advanced linear algebra operations like matrix inversion and LU decomposition.
-* **Array-like structures** Full support of [numpy-like ndarrays](https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.ndarray.html) including mixed arithmetic operations and function operations over arrays and numbers just like in Python (with the added benefit of static type checking).
+    * Advanced linear algebra operations like matrix inversion and LU decomposition.
 
-* **Expressions** Expressions are one of the ultimate goals of KMath. By writing a single mathematical expression
+* **Array-like structures** Full support of many-dimenstional array-like structures 
+including mixed arithmetic operations and function operations over arrays and numbers (with the added benefit of static type checking).
+
+* **Expressions** By writing a single mathematical expression
 once, users will be able to apply different types of objects to the expression by providing a context. Exceptions
 can be used for a wide variety of purposes from high performance calculations to code generation.
 
+* **Histograms** Fast multi-dimensional histograms.
+
+* **Streaming** Streaming operations on mathematica objects and objects buffers.
+
+* **Commons-math wrapper** It is planned to gradually wrap most parts of [Apache commons-math](http://commons.apache.org/proper/commons-math/)
+                           library in Kotlin code and maybe rewrite some parts to better suit the Kotlin programming paradigm, however there is no fixed roadmap for that. Feel free
+                           to submit a feature request if you want something to be done first.
+                           
+* **Koma wrapper** [Koma](https://github.com/kyonifer/koma) is a well established numerics library in kotlin, specifically linear algebra.
+The plan is to have wrappers for koma implementations for compatibility with kmath API.
+

-
 * **Messaging** A mathematical notation to support multi-language and multi-node communication for mathematical tasks.
 
+* **Array statistics** 
+
+* **Integration** Univariate and multivariate integration framework.
+
+* **Probability and distributions**
+
+* **Fitting** Non-linear curve fitting facilities
+
 ## Multi-platform support
 
 KMath is developed as a multi-platform library, which means that most of interfaces are declared in the [common module](kmath-core/src/commonMain).
