-`jless` is a command-line pager utility for viewing JSON files.
+[`jless`](https://pauljuliusmartinez.github.io/jless/) is a command-line
+JSON viewer. Use it as a replacement for whatever combination of `less`,
+`jq`, `cat` and your editor you currently use for viewing JSON files. It
+is written in Rust and can be installed as a single standalone binary.
 
-# Releases
+`jless` is under active development. I often stream development live on
+[Twitch](https://twitch.tv/CodeIsTheEnd).
 
-## Build Linux release:
+### Features
+
+- Clean syntax highlighted display of JSON data, omitting quotes around
+  object keys, closing object and array delimiters, and trailing commas.
+- Expand and collapse objects and arrays so you can see both the high-
+  and low-level structure of the data.
+- A wealth of vim-inspired movement commands for efficiently moving
+  around and viewing data.
+- Full regex-based search for finding exactly the data you're looking
+  for.
+
+`jless` currently supports macOS and Linux. Windows support is planned.
+
+## Installation
+
+The [releases](https://github.com/PaulJuliusMartinez/jless/releases)
+contains links to the latest release. If you have a Rust toolchain
+installed, you can build from source by running `cargo install jless`.
+

+
+The mascot of the `jless` project is Jules the jellyfish.
