+
+// Create new Spreadsheet object
+$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
+
+// add code that show the issue here...
+```
+
+
+### Which versions of PhpSpreadsheet and PHP are affected?

vendor/phpoffice/phpspreadsheet/CONTRIBUTING.md

+# Want to contribute?
+
+If you would like to contribute, here are some notes and guidelines:
+
+ - All new development happens on feature/fix branches, and are then merged to the `master` branch once stable; so the `master` branch is always the most up-to-date, working code
+ - Tagged releases are made from the `master` branch
+ - If you are going to be submitting a pull request, please fork from `master`, and submit your pull request back as a fix/feature branch referencing the GitHub issue number
+ - Code style might be automatically fixed by `composer fix`
+ - All code changes must be validated by `composer check`
+ - [Helpful article about forking](https://help.github.com/articles/fork-a-repo/ "Forking a GitHub repository")
+ - [Helpful article about pull requests](https://help.github.com/articles/using-pull-requests/ "Pull Requests")

+# Frequently asked questions
+
+## There seems to be a problem with character encoding...
+
+It is necessary to use UTF-8 encoding for all texts in PhpSpreadsheet.
+If the script uses different encoding then you can convert those texts
+with PHP's `iconv()` or `mb_convert_encoding()` functions.
+
+## Fatal error: Allowed memory size of xxx bytes exhausted (tried to allocate yyy bytes) in zzz on line aaa
+
+PhpSpreadsheet holds an "in memory" representation of a spreadsheet, so
+it is susceptible to PHP's memory limitations. The memory made available
+to PHP can be increased by editing the value of the `memory_limit`
+directive in your `php.ini` file, or by using
+`ini_set('memory_limit', '128M')` within your code.
+
+Some Readers and Writers are faster than others, and they also use
+differing amounts of memory.
+
+## Protection on my worksheet is not working?
+
+When you make use of any of the worksheet protection features (e.g. cell
+range protection, prohibiting deleting rows, ...), make sure you enable
+worksheet security. This can for example be done like this:
+
+``` php
+$spreadsheet->getActiveSheet()->getProtection()->setSheet(true);
+```
+
+## Feature X is not working with Reader\_Y / Writer\_Z
+
+Not all features of PhpSpreadsheet are implemented in all of the Reader
+/ Writer classes. This is mostly due to underlying libraries not
+supporting a specific feature or not having implemented a specific
+feature.
+
+For example autofilter is not implemented in PEAR
+Spreadsheet\_Excel\_writer, which is the base of our Xls writer.
+
+We are slowly building up a list of features, together with the
+different readers and writers that support them, in the [features cross
+reference](./references/features-cross-reference.md).
+
+## Formulas don't seem to be calculated in Excel2003 using compatibility pack?
+
+This is normal behaviour of the compatibility pack, `Xlsx` displays this
+correctly. Use `\PhpOffice\PhpSpreadsheet\Writer\Xls` if you really need
+calculated values, or force recalculation in Excel2003.
+
+## Setting column width is not 100% accurate
+
+Trying to set column width, I experience one problem. When I open the
+file in Excel, the actual width is 0.71 less than it should be.
+
+The short answer is that PhpSpreadsheet uses a measure where padding is
+included. See [how to set a column's width](./topics/recipes.md#setting-a-columns-width)
+for more details.

+# Welcome to PhpSpreadsheet's documentation
+
+![Logo](./assets/logo.svg)
+
+PhpSpreadsheet is a library written in pure PHP and providing a set of
+classes that allow you to read from and to write to different
+spreadsheet file formats, like Excel and LibreOffice Calc.
+
+## File formats supported

+
+# Getting started
+
+## Software requirements
+
+The following software is required to develop using PhpSpreadsheet:
+
+-   PHP version 5.6 or newer
+-   PHP extension php\_zip enabled
+-   PHP extension php\_xml enabled
+-   PHP extension php\_gd2 enabled (if not compiled in)
+
+### PHP version support
+
+Support for PHP versions will only be maintained for a period of six months beyond the end-of-life of that PHP version
+
+## Installation
+
+Use [composer](https://getcomposer.org) to install PhpSpreadsheet into your project:
+
+```sh
+composer require phpoffice/phpspreadsheet
+```
+
+## Hello World
+
+This would be the simplest way to write a spreadsheet:
+
+```php
+<?php
+
+require 'vendor/autoload.php';
+
+use PhpOffice\PhpSpreadsheet\Spreadsheet;
+use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
+
+$spreadsheet = new Spreadsheet();
+$sheet = $spreadsheet->getActiveSheet();
+$sheet->setCellValue('A1', 'Hello World !');
+
+$writer = new Xlsx($spreadsheet);
+$writer->save('hello world.xlsx');
+```
+
+## Learn by example
+
+A good way to get started is to run some of the samples. Serve the samples via
+PHP built-in webserver:
+
+```sh
+php -S localhost:8000 -t vendor/phpoffice/phpspreadsheet/samples
+```
+
+Then point your browser to:
+
+> http://localhost:8000/
+
+The samples may also be run directly from the command line, for example:
+
+```sh
+php vendor/phpoffice/phpspreadsheet/samples/Basic/01_Simple.php
+```
+
+## Learn by documentation
+
+For more in-depth documentation, you may read about an [overview of the
+architecture](./topics/architecture.md),
+[creating a spreadsheet](./topics/creating-spreadsheet.md),
+[worksheets](./topics/worksheets.md),
+[accessing cells](./topics/accessing-cells.md) and
+[reading and writing to files](./topics/reading-and-writing-to-file.md).
+
+Or browse the [API documentation](https://phpoffice.github.io/PhpSpreadsheet/master).
