 ## Features
 
-* Prints out top test names and their latest calculation window scores (normal fliprate and exponentially weighted moving average fliprate that take previous calculation windows into account)
+* Prints out top test names and their latest calculation window scores (normal fliprate and exponentially weighted moving average fliprate that take previous calculation windows into account).
 * Calculation grouping options:
-  * `n` days
-  * `n` runs
-* Heatmap visualization of the scores and history 
+  * `n` days.
+  * `n` runs.
+* Heatmap visualization of the scores and history.
 
 ## Parameters
 
 ### Data options (choose one)
 
 * `--test-history-csv`
-  * Give a path to a test history csv file which includes three fields: `timestamp`, `test_identifier` and `test_status`
+  * Give a path to a test history csv file which includes three fields: `timestamp`, `test_identifier` and `test_status`.
 * `--junit-files`
-  * Give a path to a folder with `JUnit` test results
+  * Give a path to a folder with `JUnit` test results.
 
 ### Calculation options
 
 * `--grouping-option`
-  * `days` to use `n` days for fliprate calculation windows
-  * `runs` to use `n` runs for fliprate calculation windows
+  * `days` to use `n` days for fliprate calculation windows.
+  * `runs` to use `n` runs for fliprate calculation windows.
 
 * `--window-size`
-  * Fliprate calculation window size `n`
+  * Fliprate calculation window size `n`.
 
 * `--window-count`
-  * History size for exponentially weighted moving average calculations 
+  * History size for exponentially weighted moving average calculations.
 
 * `--top-n`
-  * How many top highest scoring tests to print out
+  * How many top highest scoring tests to print out.
 ### Heatmap generation
 * `--heatmap`
-  * Turn heatmap generation on
-  * Two pictures generated: normal fliprate and exponentially weighted moving average fliprate score
-  * Same parameters used as with the printed statistics
