+## Linux AppImage, MacOS and Windows binaries
+
+[Lem has nightly releases](https://github.com/lem-project/lem/releases)! for Linux, MacOS and Windows.
+
+
+### How to Fix “App Is Damaged and Can’t Be Opened” on OSX
+
+Copy the app file to the applications folder and type the following in your terminal:
+```
+xattr -d com.apple.quarantine /Applications/lem.app
+```
+
+## Installation with Docker
+
+Use the ready-to-use Lem image in the GitHub Container Registry:
+
+    $ docker run --rm -it ghcr.io/lem-project/lem:latest
+
+
+or clone the Lem repository and build the Docker image:
+
+    $ docker build -t lem .
+
+You can now run it:
+
+    $ docker run --rm -it -v .:/shared lem
+
+
+## Debian/Mint/Ubuntu
+
+There is an automatic installer that works on Debian, Linux Mint and Ubuntu.
+
+Before that, install the dependencies:
+```
+sudo apt install sbcl curl git
+```
+
+Now, run the command that will install Lem:
+{{< expand "Check the script! (it runs sudo to install more depencies regarding ncurses)" >}}
+
+The sh script is located here https://lem-project.github.io/linux_installer.sh which downloads
+
+the lisp file that is interpreted for SBCL, it can be checked here https://lem-project.github.io/linux-installer.lisp
+
+
+{{< /expand >}}
+```
+curl -L https://lem-project.github.io/linux_installer.sh | bash
+```
+
+Important places from the script installation:
+- `$HOME/common-lisp/lem` (Lem installation location)
+- `/usr/local/bin/lem` (Lem symlink)
+
+
+## Installation from scratch
+
+- [sbcl](https://www.sbcl.org/)
+- [ncurses](https://invisible-island.net/ncurses/announce.html#h2-overview)
+- [qlot](https://github.com/fukamachi/qlot)
+- [git](https://git-scm.com/)
+
+### Optional dependencies
+
+This is a list of optional programs that we advise to install along of Lem:
+
+```
+fd
+```
+
+- [fd](https://github.com/sharkdp/fd) or `fd-find` on Debian repositories: if present, Lem will use it in commands that find files recursively (see Usage: Opening Files). `fd` respects .gitignore by default and ignores common large development directories such as `node_modules/`. If it isn't present, Lem will fallback to a full Lisp solution.
+
+### Install SBCL and ncurses library
+- Debian-like distro
+```
+sudo apt install sbcl libncurses5-dev build-essential fd-find
+```
+
+- Fedora
+```
+sudo yum install sbcl ncurses-devel make automake gcc gcc-c++ fd-find
+```
+
+- OpenSuse
+```
+sudo zypper install sbcl ncurses-devel make devel_basis fd
+```
+
+### Install qlot
+- Automatic installer
+```
+curl -L https://qlot.tech/installer | bash
+```
+For an alternative installation, https://github.com/fukamachi/qlot#installation
+
+
+### Build the executables
+
+- Create the directories
+
+```
+mkdir $HOME/common-lisp && cd $HOME/common-lisp
+```
+```
+git clone https://github.com/lem-project/lem.git
+cd lem && make ncurses
+```
+
+or run `make sdl2-ncurses` to build Lem with the two interfaces in it. Then choose the interface at startup with `-i / --interface`, either "sdl2" or "ncurses".
+
+
+### Add the executable to PATH
+- Copying the PATH to `~/.bashrc`
+```
+export PATH="$HOME/common-lisp/lem:$PATH"
+```
+
+## Installation with roswell (deprecated)
+
+> Note: the installation with Roswell is deprecated.
+
+Please install roswell at first, [Roswell Installation Guide](https://github.com/roswell/roswell/wiki/Installation).
+
+After that, please follow the steps bellow.
+
+1. Install lem by roswell
+
+```
+$ ros follow-dependency=t install lem-project/lem
+```
+
+2. Add the PATH in the initialization file (such as `~/.bashrc`)
+```
+export PATH=$PATH:~/.roswell/bin
+```
