+
+A node module to edit a string with a users preferred text editor using $VISUAL or $ENVIRONMENT.
+
+Version: 3.1.0
+
+As of version 3.0.0, the minimum version of node supported is 4.
+
+## Install
+
+`npm install external-editor --save`
+
+## Usage
+
+A simple example using the `.edit` convenience method
+
+    import {edit} from "external-editor";
+    const data = edit('\n\n# Please write your text above');
+    console.log(data);
+
+A full featured example
+
+    import {ExternalEditor, CreateFileError, ReadFileError, RemoveFileError} from "external-editor"
+    
+    try {
+        const editor = new ExternalEditor();
+        const text = editor.run() // the text is also available in editor.text
+        
+        if (editor.last_exit_status !== 0) {
+            console.log("The editor exited with a non-zero code");
+        }
+    } catch (err) {
+        if (err instanceOf CreateFileError) {
+            console.log('Failed to create the temporary file');
+        } else if (err instanceOf ReadFileError) {
+            console.log('Failed to read the temporary file');
+        } else if (err instanceOf LaunchEditorError) {
+            console.log('Failed to launch your editor');
+        } else {
+            throw err;
+        }
+    }
+    
+    // Do things with the text
+    
+    // Eventually call the cleanup to remove the temporary file
+    try {
+        editor.cleanup();   
+    } catch (err) {
+         if (err instanceOf RemoveFileError) {
+             console.log('Failed to remove the temporary file');
+         } else {
+            throw err
+        }
+    }
+    
+    
+#### API
+**Convenience Methods**
+
+- `edit(text, config)`
+    - `text` (string) *Optional* Defaults to empty string
+    - `config` (Config) *Optional* Options for temporary file creation
+    - **Returns** (string) The contents of the file
+    - Could throw `CreateFileError`, `ReadFileError`, or `LaunchEditorError`, or `RemoveFileError`
+- `editAsync(text, callback, config)`
+    - `text` (string) *Optional* Defaults to empty string
+    - `callback` (function (error, text))
+        - `error` could be of type `CreateFileError`, `ReadFileError`, or `LaunchEditorError`, or `RemoveFileError`
+        - `text`(string) The contents of the file
+    - `config` (Config) *Optional* Options for temporary file creation
+
+
+**Errors**
+
+- `CreateFileError` Error thrown if the temporary file could not be created. 
+- `ReadFileError` Error thrown if the temporary file could not be read.
+- `RemoveFileError` Error thrown if the temporary file could not be removed during cleanup.
+- `LaunchEditorError` Error thrown if the editor could not be launched.
+
+**External Editor Public Methods**
+
+- `new ExternalEditor(text, config)`
+    - `text` (string) *Optional* Defaults to empty string
+    - `config` (Config) *Optional* Options for temporary file creation
+    - Could throw `CreateFileError`
+- `run()` Launches the editor.
+    - **Returns** (string) The contents of the file
+    - Could throw `LaunchEditorError` or `ReadFileError`
+- `runAsync(callback)` Launches the editor in an async way
+    - `callback` (function (error, text))
+        - `error` could be of type `ReadFileError` or `LaunchEditorError`
+        - `text`(string) The contents of the file
+- `cleanup()`  Removes the temporary file.
+    - Could throw `RemoveFileError`
+    
+**External Editor Public Properties**
+
+- `text` (string) *readonly* The text in the temporary file.
+- `editor.bin` (string) The editor determined from the environment.
+- `editor.args` (array) Default arguments for the bin
+- `tempFile` (string) Path to temporary file. Can be changed, but be careful as the temporary file probably already 
+    exists and would need be removed manually.
+- `lastExitStatus` (number) The last exit code emitted from the editor.
+    
+**Config Options**
+
+- `prefix` (string) *Optional* A prefix for the file name.
+- `postfix` (string; *Optional* A postfix for the file name. Useful if you want to provide an extension.
+- `mode` (number) *Optional* Which mode to create the file with. e.g. 644
+- `template` (string) *Optional* A template for the filename. See [tmp](https://www.npmjs.com/package/tmp).
+- `dir` (string) *Optional* Which path to store the file.
+    
+## Errors
+
+All errors have a simple message explaining what went wrong. They all also have an `originalError` property containing
+the original error thrown for debugging purposes.
+    
+## Why Synchronous?
+ 
+Everything is synchronous to make sure the editor has complete control of the stdin and stdout. Testing has shown 
+async launching of the editor can lead to issues when using readline or other packages which try to read from stdin or 
+write to stdout. Seeing as this will be used in an interactive CLI environment, I made the decision to force the package
+to be synchronous. If you know a reliable way to force all stdin and stdout to be limited only to the child_process,
+please submit a PR.
+
+If async is really needed, you can use `editAsync` or `runAsync`. If you are using readline or have anything else
+listening to the stdin or you write to stdout, you will most likely have problem, so make sure to remove any other 
+listeners on stdin, stdout, or stderr.
+
+## Demo
+
+[![asciicast](https://asciinema.org/a/a1qh9lypbe65mj0ivfuoslz2s.png)](https://asciinema.org/a/a1qh9lypbe65mj0ivfuoslz2s)
+
+## Breaking Changes from v2 to v3
+
+- NodeJS 0.12 support dropped.
+- Switched to named imports.
+- All "snake_cased" variables and properties are now "camelCased".
+    - `ExternalEditor.temp_file` is now `ExternalEditor.tempFile`.
+    - `ExternalEditor.last_exit_status` is now `ExternalEditor.lastExitStatus`.
+    - `Error.original_error` is now `Error.originalError`.
