Installation

Prerequisites

Pre-built binaries and editor extensions require no additional tooling. To build from source (via cargo install or cargo build), you need:

Tool	Minimum version	Purpose
Rust	1.80	Compiler and cargo
Zig	0.15.2	Zig FFI layer (md4c parser and SIMD acceleration)

The Zig FFI layer is statically linked into the binary — the build will fail if Zig is not installed or is below the minimum version.

Install from crates.io

cargo install markymark-cli

This builds and installs the markymark binary to ~/.cargo/bin/. To upgrade, run the same command again.

Pre-built binaries

Download a binary for your platform from GitHub Releases:

Platform	Binary name
macOS ARM	markymark-aarch64-apple-darwin
macOS Intel	markymark-x86_64-apple-darwin
Linux x86_64	markymark-x86_64-unknown-linux-gnu
Linux ARM64	markymark-aarch64-unknown-linux-gnu
Windows x64	markymark-x86_64-pc-windows-msvc.exe

On macOS/Linux, make the binary executable and move it onto your PATH:

chmod +x markymark-*
mv markymark-* /usr/local/bin/markymark

If your platform is not listed, use cargo install markymark-cli to build from source.

VS Code extension

The VS Code extension bundles the correct binary for your platform and starts the LSP server automatically for .md and .mdx files.

Install from a GitHub release .vsix file, or build from source in markymark-vscode/. If no bundled binary matches your platform, point markymark.path in VS Code settings to a manually installed binary.

Claude Code plugin

/plugin install markymark

This installs markymark as both an LSP server and MCP tool provider inside Claude Code.

To install manually, download the plugin archive from GitHub Releases and extract it:

gh release download --repo sethyanow/markymark --pattern 'markymark-plugin-*.tar.gz'
tar -xzf markymark-plugin-*.tar.gz

Neovim

Neovim can use markymark as an LSP server. See the Editor Setup section for configuration details once you have the binary installed via any method above.

Verify installation

markymark --version
markymark --help

The --lsp flag starts the LSP server (stdio) and --mcp starts the MCP server.
