+# Wild GraphQL Datasource
+
+This is a Grafana datasource that aims to make requesting timeseries data via a GraphQL endpoint easy.
+
+## Building and Development
+
+### Setup your system
+
+* Web requirements
+  * Install nvm https://github.com/nvm-sh/nvm#installing-and-updating
+* Backend requirements
+  * Install go https://go.dev/doc/install
+  * Install Mage https://magefile.org/
+* Grafana requirements
+  * Install Docker: https://docs.docker.com/engine/install/
+    * `npm run server` command uses `docker compose` to bring up Grafana
+  * Make sure your user is part of the `docker` group
+
+An example of commands you *could* run.
+Customize this setup to your liking.
+
+```shell
+# install nvm https://github.com/nvm-sh/nvm#installing-and-updating
+nvm install 20
+
+# NOTICE: This `rm` command will remove your existing go installation
+rm -rf ~/go 
+wget -c https://dl.google.com/go/go1.21.5.linux-amd64.tar.gz -O - | tar -xz -C ~/
+echo 'export PATH="$PATH:$HOME/go/bin"' >> ~/.bashrc
+
+cd ~/Documents/Clones
+git clone https://github.com/magefile/mage
+cd mage
+go run bootstrap.go
+
+# *docker installation not shown*
+# *adding $USER to docker group not shown*
+```
+
+### Setup build environment
+
+```shell
+go get -u github.com/grafana/grafana-plugin-sdk-go
+go mod tidy
+mage -v
+mage -l
+
+npm install
+npm run dev
+npm run build
+```
+
+### Test inside Grafana instance
+
+Note that `npm run server` uses `docker compose` under the hood.
+
+```shell
+npm run server
+```
+
+### Recommended development environment
+
+You may choose to use VS Code, which has free tools for developing TypeScript and Go code.
+IntelliJ IDEA Ultimate is a non-free choice that has support for both TypeScript and Go code.
+Alternatively, WebStorm (also not free) covers TypeScript development and GoLand covers Go development.
