+# JSONEdit
+
+This is an editor for JSON files, that also supports YAML. 
+
+## Features
+
+- Interactive terminal TUI application
+- Makes use of Unicode glyphs in 16 magnificent colors!
+- Handles array, objects and values
+- Folding of array and object keys
+- Core edit operations: insert, edit, delete
+- A minimum of dependencies
+- ~300KB executable PHAR
+
+## Installing
+
+The recommended way to install and run JSONEdit is by grabbing the PHAR from
+the latest release:
+
+- [https://dev.noccylabs.info/noccy/jsonedit/releases](https://dev.noccylabs.info/noccy/jsonedit/releases)
+
+You can also clone the respository and use [Box](https://box-project.github.io/box/)
+to build the .phar yourself:
+
+```bash
+$ git clone https://dev.noccylabs.info/noccy/jsonedit
+$ cd jsonedit
+$ composer install
+$ box compile
+$ mv bin/jsonedit.phar ~/bin/jsonedit
+```
+
+## Using
+
+JSONEdit is controlled using hotkeys. The essential keys are always displayed
+at the bottom of the screen.
+
+### Creating a document from scratch
+
+1. Run `jsonedit` from your shell.
+2. Press **I** to insert a new key. Select "Object" in the menu. Enter "services" and press enter.
+3. Select the newly created "services" key and press **I** to insert another object. Enter "nginx" and press enter.
+4. Select the newly created "nginx" key. Press **i** to insert a value. Enter "image" for key and "nginx" for value.
+5. Press **I** and select "Array". Enter "ports" and press enter.
+6. Select the "ports" key and press **i**. Enter "80:80" and press enter.
+7. Press **^W** to save the file. Enter "compose.yaml" and press enter.
+8. Press **^X** to exit.
+
+You should now have a `compose.yaml` file that spins up a completely useless
+unconfigured nginx container.
+
+### Editing a document
+
+1. Run `jsonedit <filename>` from your shell.
+2. Find the value you want to edit and press **e**.
+3. Enter the value usng valid JSON value encoding, for example `"1234"` for the
+   string 1234, and `1234` for the integer 1234. Unparsable JSON will be used
+   as a verbatim string.
+4. Make any additional edits, including using **i** and **I** to insert new
+   keys and values, and **D** to delete values.
+5. Press **^W** to save the file. Enter the filename to write and press enter.
+6. Press **^X** to exit.
+
+### Folding
+
+To fold and unfold keys, use the following keys:
+
+- **+** - Toggle folding of current key
+- **-** - Collapse all nodes but the first
+- **←** - Collapse current key, or go to parent if a value or already collapsed
+- **→** - Expand current key
+
+### Customizing JSONEdit
+
+Use the following keys to customize the appearance of JSONEdit. The settings
+will be persisted for the next session if the directory `~/.config/jsonedit`
+exists.
+
+- **g** - Toggle indentation guides
+- **t** - Toggle tail line guide
+- **b** - Toggle icons before keys
+- **c** - Toggle compact mode
+
+## Caveats
+
+- **YAML comments/formatting is not preserved** - When reading YAML, comments are
+  not preserved, and YAML formatting is not preserved when writing YAML.
