+**This repo is a fork** of [Fabrice Bellard's TinyEMU project\[v2019-12-21]](https://bellard.org/tinyemu),
 a lightweight RISC-V and x86 emulator. Specifically migrating the project to
 the latest stable release of `enscriptem`. I provide a `flake.nix` dev shell too *(cause I'm super nice)*.

+JSLinux demo
+============
+
+You must copy all the files to a directory on a web server in order to
+run the demo (it is needed so that the XML HTTP Requests work
+correctly). Assuming it is installed in http://localhost/jslinux,
+explore in a browser:
+
+http://localhost/jslinux
+
+A minimal busybox distribution for RISCV-64 and x86 is provided. The
+RISCV-64 version is executed by default. To run the x86 version,
+explore:
+
+http://localhost/jslinux?cpu=x86
+
+The source jslinux.js can be modified to change the default
+configuration.
+
+More complete Linux distributions (such as buildroot) can be used
+provided you keep using the same precompiled Linux kernels. The
+TinyEMU 'splitimg' tool must be used to convert a diskimage to a list
+of files. For example:
+
+splitimg root-riscv64.bin root-riscv64 256
+
+The demo VM configurations are in root-riscv64.cfg and root-x86.cfg.
