 ## Features

 - Drag and drop
     - Operations can be dragged in and out of the recipe list, or reorganised.
-     - Files can be dragged over the input box to load them directly.
+     - Files can be dragged over the input box to load them directly into the browser.
 - Auto Bake
-     - Whenever you modify the input or the recipe, CyberChef will automatically “bake” for you and produce the output immediately.
+     - Whenever you modify the input or the recipe, CyberChef will automatically "bake" for you and produce the output immediately.
     - This can be turned off and operated manually if it is affecting performance (if the input is very large, for instance).
-     - If any bake takes longer than 200 milliseconds, auto bake will be switched off automatically to prevent further performance issues.
 - Breakpoints
     - You can set breakpoints on any operation in your recipe to pause execution before running it.
     - You can also step through the recipe one operation at a time to see what the data looks like at each stage.
 - Save and load recipes
-     - If you come up with an awesome recipe that you know you’ll want to use again, just click save and add it to your local storage. It'll be waiting for you next time you visit CyberChef.
-     - You can also copy a URL which includes your recipe and input which can be shared with others.

+     - You can also copy the URL, which includes your recipe and input, to easily share it with others.
 - Search
     - If you know the name of the operation you want or a word associated with it, start typing it into the search field and any matching operations will immediately be shown.
 - Highlighting
-     - When you highlight text in the input or output, the offset and length values will be displayed and, if possible, the corresponding data will be highlighted in the output or input respectively (example: [highlight the word 'question' in the input to see where it appears in the output][8]).

 - Save to file and load from file
-     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field (note that files larger than about 500kb may cause your browser to hang or even crash due to the way that browsers handle large amounts of textual data).
+     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field. Files up to around 500MB are supported (depending on your browser), however some operations may take a very long time to run over this much data.
 - CyberChef is entirely client-side
-     - It should be noted that none of your input or recipe configuration is ever sent to the CyberChef web server - all processing is carried out within your browser, on your own computer.
-     - Due to this feature, CyberChef can be compiled into a single HTML file. You can download this file and drop it into a virtual machine, share it with other people, or use it independently on your desktop.

                                    <p>A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.</p><br>

                                    <h5><strong>Why</strong></h5>
                                    <p>Digital data comes in all shapes, sizes and formats in the modern world – CyberChef helps to make sense of this data all on one easy-to-use platform.</p><br>

                                    <h5><strong>How</strong></h5>
                                    <p>The interface is designed with simplicity at its heart. Complex techniques are now as trivial as drag-and-drop. Simple functions can be combined to build up a "recipe", potentially resulting in complex analysis, which can be shared with other users and used with their input.</p>
                                    <p>For those comfortable writing code, CyberChef is a quick and efficient way to prototype solutions to a problem which can then be scripted once proven to work.</p><br>

                                    <h5><strong>Who</strong></h5>
                                    <p>It is expected that CyberChef will be useful for cybersecurity and antivirus companies. It should also appeal to the academic world and any individuals or companies involved in the analysis of digital data, be that software developers, analysts, mathematicians or casual puzzle solvers.</p><br>
