+## Build
+
+Use the provided build script to locally build images via Docker (disable BuildKit with `DOCKER_BUILDKIT=0`).
+
+```bash
+scripts/build <image> [tag]
+```
+
+Add additional `docker build` flags via `DOCKER_BUILD_ARGS` variable as needed.

+# ~ajhalili2006's custom devenv images
+
+## Build
+
+You need at least 2 GB of storage and a stable and fast internet connection
+to build
+
+> [!note]
+> It's best to run the scripts at the root of the repo (or use `direnv` for this purpose) instead of prefixing it with `$(git rev-parse --show-toplevel)/`.
+> You may also run into issues if the output of `git rev-parse --show-toplevel` has spaces in it.
+
+### Base image
+
+For base image:
+
+```bash
+$(git rev-parse --show-toplevel)/scripts/build devenv/base [custom-image-name]
+```
+
+By default, the built image will be tagged with `dock.mau.dev/andreijiroh-dev/docker-images/devenv/base:localdev` which
+you'll need on building subsequent images.
+
+**Supported build args**:
+
+* `BUILDPACK_DEPS_TAG`: Use this to lock into specific Ubuntu LTS release at specific SHA-256 digest of the image.
+* `dotfiles` - Git-over-HTTPS clone URL of your dotfiles repository that compatible with `yadm`.
+* `dotfilesBranch` - Branch name from your dotfiles repo if you seperate configuration files between environments via branches.
+
+### Google Cloud Shell
+
+> [!warning]
+> The `gcr.io/cloudshell-images/cloudshell` base image weights at 22.44 GB, so you may need to spare some additional GBs of storage
+> since we're doing `apt-get upgrade` behind the scenes.
+
+```bash
+scripts/build devenv/cloudshell
+
+# on Google Cloud Shell
+cd docker/devenv/cloudshell && cloudshell env build-local
+```
+
+### Gitpod workspace image
+
+To build Gitpod-optmized image:
+
+```bash
+# To use your local build, pass --build-arg flag as value of DOCKER_BUILD_ARGS
+# when running scripts/build.
+DOCKER_BUILD_ARGS="--build-arg base=dock.mau.dev/andreijiroh-dev/docker-images/devenv/base:localdev" $(git rev-parse --show-toplevel)/scripts/build devenv/gitpod
+```
+
+Once built, you may want to use it to run a debug workspace in Gitpod.
+
+```bash
+# You may need to authenicate with your preferred Docker registry for the script
+# to work properly.
+script/publish-to-staging dock.mau.dev/andreijiroh-dev/docker-images/devenv/gitpod:localdev <target-repo-tag>
+```
