+# C++ Intellisense for Spark on Windows (VS Code)
+**Steps**
+1. Install the **[C++ extension][cpp ext]**
+2. Install the **[CMake extension][cmake ext]**
+3. Copy `c_cpp_properties.json` from this folder to `$workspaceFolder/.vscode/`
+4. In the VS Code Command Palette, run **CMake: Select Configure Preset**, then
+   select '**spark**' from the dropdown
+
+**Notes**
+* Intellisense won't work for generated files/types until you build libspark
+
+# C++ Intellisense for Sparkd on Linux (VS Code)
+1. Install the **[CMake extension][cmake ext]**
+2. Install the **[Clangd extension][clangd ext]**
+3. (Optional) Install the **[C++ extension][cpp ext]** (*needed for debugging,
+   but intellisense should work without it*).
+4. If the **[C++ extension][cpp ext]** is installed, disable its intellisense in
+  your workspace settings (*Clangd intellisense is better*)
+   ```
+   "C_Cpp.intelliSenseEngine": "disabled"
+   ```
+5. In the VS Code Command Palette, run **CMake: Select Configure Preset**, then select the
+  **[preset][cmake presets]** you wish to build from the dropdown
+   * *The **Clang** presets may work best with the **Clangd** extension*
+   * *Intellisense won't work for generated files/types until you build libspark*
+
+# Build Sparkd on Linux
+
+**Notes**
+* Sparkd is built using **[CMakePresets][cmake presets]**
+
+**Steps**
+1. Set up the **[Python virtual environment][py venv]**<br>
+   * *Run commands from the repo root dir unless otherwise noted*
+   1. Create the virtual environment
+      ```
+      python3 -m venv .venv
+      ```
+   2. Activate the virtual environment
+      ```
+      . .venv/bin/activate
+      ```
+   3. Verify `python` in the venv is first in the path<br>
+      * ***Expected:** output shows the absolute path to `.venv/bin/python`*
+      ```
+      which python
+      ```
+   4. Update `pip`<br>
+      * *The venv module initializes virtual environments with its own version
+        of pip, rather than the system's version. Even if the latter is up-to-date, the
+        former may not be.*
+      ```
+      python -m pip install --upgrade pip
+      ```
+   5. Install the packages listed `requirements.txt`
+      ```
+      pip install -r requirements.txt
+      ```
+2. Build **Sparkd**<br>
+   * From the terminal
+      ```
+      tools/build_sparkd.sh
+      ```
+      * *Run with `--help` to see available options*
+   * From VS Code
+      1. Install the **[CMake extension][cmake ext]**
+      2. In the VS Code Command Palette, run **CMake: Select Configure
+         Preset**, then select the **[preset][cmake presets]** you wish to
+         build from the dropdown
+      3. Run **CMake: Build** in the command palette.

+# Sparkd Dev Container
+## How to create a VS Code [Dev Container][dev containers]
+
+1. Make sure the **[Dev Containers][dev containers ext]** extension is installed
+1. Make sure your Docker image is up to date
+   ```
+   docker pull bluetradingsystems/sparkd-dev:latest
+   ```
+1. Copy **devcontainer.json** from this folder to **$workspaceFolder/.devcontainer/**.
+
+1. In the VS Code Command Palette, run **Dev Containers: Reopen in Container**
+
+---
+## How to create a Sparkd Container in the terminal (without VS Code)
+
+1. Make sure your Docker image is up to date
+   ```
+   docker pull bluetradingsystems/sparkd-dev:latest
+   ```
+2. Start the container
+   ```
+   # Replace <cont_name> with a name for the container. The container's
+   # "$HOME" dir will be mounted to "$HOME/.sparkd-dev/mounts/<cont_name> on
+   # the host
+   
+   ./start_docker.sh --container <cont_name> --mount-existing
+   ```
+   * *Replace <cont_name> with a name for the container*
+   * *The container's `$HOME` dir will be mounted to
+   `$HOME/.sparkd-dev/mounts<cont_name>` on the host*<br>
+   * *Run: `./start_docker.sh --help` to see additional options*
+3. *(Optional) Attach VS Code to the running container.*<br>
+Run **Dev Containers: Attach to Running Container** from the command palette,
+then select your container in the dropdown
+
+---
+## How to update the Docker image
+
+1. Change the image by modifying the Dockerfile (don't tag arbitrary
+  images on your machine and push them to our repo on Docker Hub)
+
+1. After modifying the Dockerfile, (re)build the image
+   ```
+   # Run in this dir
+   docker build -t bluetradingsystems/sparkd-dev:latest .
+   ```
+   ***Note:** Your docker login must have write permissions to push to the
+   [sparkd-dev][docker repo sparkd-dev] repository*
+
+2. Commit the changes to Dockerfile in git
+
+3. Push the new image to Docker Hub
+
+   ```
+   docker push johncolvin/bluetradingsystems:sparkd-dev
+   ```
+   ***Note:** The image doesn't have to be on Docker Hub, we can simply build
+   it from scratch on our local machines (with the Dockerfile). However, this
+   takes time. It is significantly quicker to download a prebuilt image, so we
+   store it on a remote repository to save time when setting up a new dev
+   machine.*
