-Build the example project by running `make` from the terminal or the VSCode extension.
+Several useful VSCode extentsions will be installed, including a Z80 assembly language server, Z80 and C debugger, Makefile support, BASIC syntax highlighter and more.
+
+Thanks to the many authors of these wonderful tools and extensions; to think what we could have made with these in 1985!
+
+## Install
+
+This devcontainer should work in Windows, Linux and MacOS. It is recommended to install:
+- git, then configure user name and email address
+- docker, or alternative like podman
+- (Windows only, optional) Windows Subsystem for Linux, version 2
+- Microsoft's vscode
+- the "Dev Containers" extension (from Microsoft) within vscode
+
+Make sure docker (or your alternative) is running before trying to use the devcontainer.
+
+## Usage
+
+![A terminal window running the commands outlined below](res/speccydev.gif)
+
+Open a terminal and navigate to the directory which will contain your Spectrum projects. Run `git clone https://github.com/mcphail/speccydev.git your_project_name` and enter that directory. Start vscode by running `code .` inside the directory.
+
+If you have installed the Dev Containers extension correctly, a popup will offer to reload the project within a devcontainer. Go ahead and allow this. The first time you use this devcontainer, it may take a few minutes to download and start. It should open more quickly on subsequent use.
+
+Open the bottom bar in vscode to expose the terminal or select "Terminal -> New Terminal" from the menu bar. Try running some Linux commands like `ls -lh` or `date`. Build the example project by running `make` from the terminal or the VSCode extension. Experiment with editing some of the source files and running `make` again. Experiment with some of the assemblers, compilers and other tools mentioned above. The `Makefile` contains example usage of tools like sjasmplus, zmakebas, Boriel's BASIC and the FUSE utilities.
+
+When you are ready to start your own project, run `make start_new_project` to wipe out the example code and start afresh.
+
+## Debugging
+
+Debug in the built in simulator or in CSpect externally (example CSpect invocation on Windows would be `CSpect.exe -w2 -debug -remote`). The simulator is set up to expect a binary called `myprog.sna` and a map file called `myprog.sld` but this can be configured in the `.vscode/launch.json` file.
 
-Debug in the built in simulator or in CSpect externally (example CSpect invocation on Windows would be `CSpect.exe -w2 -debug -remote`).
 *Note: to use CSpect debugging from a Linux host you will have to edit the file `.vscode/launch.json` to change the `"hostname"` parameter to `"localhost"`*
