E.g., for Linux, it would be the `html2md_verxx_linux_amd64.tar.gz` file. - Available OS for binary executables are * Linux * Mac OS (darwin) * Windows - If your OS and its architecture is not available in the download list, please let me know and I'll add it. - The manual installation is just to unpack it and move/copy the binary executable to somewhere in `PATH`. For example, ``` sh tar -xvf html2md_*_linux_amd64.tar.gz sudo mv -v html2md_*_linux_amd64/html2md /usr/local/bin/ rmdir -v html2md_*_linux_amd64 ``` ### Distro package - [Packages available for Linux distros](https://cloudsmith.io/~suntong/repos/repo/packages/) are * [Alpine Linux](https://cloudsmith.io/~suntong/repos/repo/setup/#formats-alpine) * [Debian](https://cloudsmith.io/~suntong/repos/repo/setup/#formats-deb) * [RedHat](https://cloudsmith.io/~suntong/repos/repo/setup/#formats-rpm) The repo setup instruction url has been given above. For example, for [Debian](https://cloudsmith.io/~suntong/repos/repo/setup/#formats-deb) -- ### Debian package ```sh curl -1sLf \ 'https://dl.cloudsmith.io/public/suntong/repo/setup.deb.sh' \ | sudo -E bash # That's it. You then can do your normal operations, like sudo apt update apt-cache policy html2md sudo apt install -y html2md ``` ## Install Source To install the source code instead: ``` go install github.com/suntong/html2md@latest ``` ## Author Tong SUN ![suntong from cpan.org](https://img.shields.io/badge/suntong-%40cpan.org-lightgrey.svg "suntong from cpan.org") _Powered by_ [**WireFrame**](https://github.com/go-easygen/wireframe) [![PoweredBy WireFrame](https://github.com/go-easygen/wireframe/blob/master/PoweredBy-WireFrame-Y.svg)](http://godoc.org/github.com/go-easygen/wireframe) the _one-stop wire-framing solution_ for Go cli based projects, from _init_ to _deploy_. ## Contributors ✨ Thanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)):
