-# B-Trees in Erlang
-
-[![Build Status](https://travis-ci.org/walter-weinmann/b_trees.svg?branch=master)](https://travis-ci.org/walter-weinmann/b_trees)
-
-The additional documentation consists of the following parts:
-
-1. [Performance] (https://github.com/walter-weinmann/b_trees/wiki/Performance) gives an idea about the performance of the functions in comparison to the OTP module gb_trees.
-2. [References:] (https://github.com/walter-weinmann/b_trees/wiki/References) points out some external documentation.
-3. [Testing:] (https://github.com/walter-weinmann/b_trees/wiki/Testing) gives a general overview of the test facilities.

-### 1. Environment
-
-All functions were tested with a processor Intel Core i7-6500U including 16 GB of ram. Each function (except largest/1 and smallest/1) was stress tested 10'000 times.  
-
-### 2. Results
-
-The results of the performance measurements can be found in the following Microsoft Excel file: [Performance] (https://github.com/walter-weinmann/b_trees/wiki/Performance_10000.xlsx).

-### 1. Test Environment
-
-All files related to **common test** and **eunit** can be found in the directory `test`. The test components in directory `test` are:
-
-- the **common test** suites `b_trees_SUITE.erl` and `performance_SUITE.erl`,
-- the **eunit** test file `b_trees_test.erl`.
-
-Both `b_trees_SUITE.erl` and `b_trees_test.erl` apply the same tests. Furthermore, the following files have been adjusted:
-
-- `.gitignore`: defines the test beam files and the test result files to be ignored,
-- `.travis.yml`: adds a `./rebar3 ct` command (`after success`),
-- `rebar.config`: defines the parameters for **common test**, **coverage analysis** and **eunit**. 
-
-### 2. Running Tests
-
-**Common Test**, **eunit** and **coverage analysis** can all be executed from the command line with the appropriate `rebar3` commands. The execution of **common test** is also included in Travis CI.
-
-### 3. Checking Test Results
-
-The results of the **common test** execution can be checked in the following file:
- 
-    file:///.../b_trees/_build/test/logs/index.html
-
-The results of the **coverage analysis** can be checked in the following file:
- 
-    file:///.../b_trees/_build/test/cover/index.html
-
-### 4 Travis CI
-
-**Common Test** is currently configured as an `after success` script in Travis CI. This has the disadvantage, that the build of **b_trees** is marked as successful even if **common test** fails.
