+By default, Dokku will remove the contents of the `.git` before triggering a build for a given app. This is generally a safe default as shipping the entire source code history of your app in the deployed image artifact is unnecessary as it increases bloat and potentially can leak information if there are any security issues with your app code.

 ## Compilable plugins (Golang, Java(?), C, etc.)
-When developing a plugin, you must implement the `install` trigger such that it outputs the built executable(s) using a directory structure that implements the plugin's desired command and/or triggers the API. See the [smoke-test-plugin](https://github.com/dokku/smoke-test-plugin) for an example.
 
+When developing a plugin, the `install` trigger must be implemented such that it outputs the built executable(s) using a directory structure that implements the plugin's desired command and/or triggers the API. See the [smoke-test-plugin](https://github.com/dokku/smoke-test-plugin) for an example.
 
 ## Command API
+
 There are 3 main integration points: `commands`, `subcommands/default`, and `subcommands/<command-name>`.
 
 ### `commands`
+
 Primarily used to supply the plugin's usage/help output. (i.e. [plugin help](https://github.com/dokku/dokku/tree/master/plugins/plugin/commands)).
 
 ### `subcommands/default`
+
 Implements the plugin's default command behavior. (i.e. [`dokku plugin`](https://github.com/dokku/dokku/tree/master/plugins/plugin/subcommands/default)).
 
 ### `subcommands/<command-name>`
+
 Implements the additional command interface and will translate to `dokku plugin:cmd` on the command line. (i.e. [`dokku plugin:install`](https://github.com/dokku/dokku/tree/master/plugins/plugin/subcommands/install)).
 
+# Plugin Building Tips
+
+## Always create a `plugin.toml`
+
+The `plugin.toml` file is used to describe the plugin in help output, and helps users understand the purpose of the plugin. This _must_ have a description and a version. The version _should_ be bumped at every plugin release.
+
+```toml
+[plugin]
+description = "dokku example plugin"
+version = "0.1.0"
+[plugin.config]
+```
+
+## Files should be executable
+
+Commands, subcommands, triggers and source shell scripts should all be executable. On a Unix-like machine, the following command can be used to make them executable:
+
+```shell
+chmod +x path/to/file
+```
+
+Non-executable commands, subcommands, and triggers will be ignored.
+
+## Use the `pipefail` bash option
+
+Consider whether to include the `set -eo pipefail` option. Look at the following example:
+
+```shell
+IMAGE=$(docker images | grep "user/repo" | awk '{print $3}')
+if [[ -z $IMAGE ]]; then
+  dokku_log_fail "user/repo image not found... Did you run 'dokku plugin:install'?"
+fi
+```
+
+If `user/repo` doesn't exist, Dokku exits just before the `awk` command and the `dokku_log_fail` message will never go to `STDOUT`. printed with echo. The `set -e` option should be used in this case.
+
+Here is the `help` entry for `set`:
+
+```
+help set
+Options:
+  -e  Exit immediately if a command exits with a non-zero status.
+  -o option-name
+      pipefail     the return value of a pipeline is the status of
+                   the last command to exit with a non-zero status,
+                   or zero if no command exited with a non-zero status
+```
+
+## Support trace mode
+
+Trace mode is useful for getting debugging output from plugins when the `--trace` flag is specified or `dokku trace:on` is triggered. This should be done at the top of each shell script:
+
+```shell
+#!/usr/bin/env bash
+set -eo pipefail
+[[ $DOKKU_TRACE ]] && set -x
+```
+
+In the above example, the third line enables bash's debug mode, which prints command traces before executing command.
+
+## Verify the existence of dependencies
+
+If a plugin depends on a specific command-line tool, check whether that tool exists before utilizing it. Either `command -v` or `which` may be used to do so:
+
+```shell
+# `command -v` example
+if ! command -v "nginx" &>/dev/null; then
+  log-fail "Missing nginx, install it"
+fi
+
+# `which` example
+if ! which nginx >/dev/null 2>&1; then
+  log-fail "Missing nginx, install it"
+fi
+```
+
+In cases where a dependency should be installed before the plugin can be used at all, use the `dependencies` plugin trigger to install the dependency.
+
+## Implement a help command
+
+For plugins which expose commands, implement a `help` command. This may be empty, but should contain a listing of all available commands.
+
+Commas - `,` - are used in the help output for columnizing output. Verify that the plugin conforms to the spec by running `dokku help --all` and manually verifying the output.
+
+See the sample plugin below for an example.
+
+## Namespace commands
+
+All commands *should* be namespaced. In cases where a core plugin is overriden, the plugin _may_ utilize the a namespace in use by the core, but generally this should be avoided to reduce confusion as to where the command is implemented.
+
+## Implement a proper catch-all command
+
+As of 0.3.3, a catch-all should be implemented that exits with a `DOKKU_NOT_IMPLEMENTED_EXIT` code. This allows Dokku to output a `command not found` message.
+
+See the sample plugin below for an example.
+
+## Set app config without restarting
+
+In the case that a plugin needs to set app configuration settings and a restart should be avoided (default Heroku-style behavior) these "internal" commands provide this functionality:

+
+## Expose functionality in a `functions` file
+
+To allow other plugins access to (some of) a plugin's functionality, functions can expose by including a `functions` file in the plugin for others to source. All functions in that file should be considered publicly accessible by other plugins.
+
+Any functions that must be kept private should reside in the plugin's `trigger/` or `commands/` directories. Other files may also be used to hide private functions; the official convention for hiding private functions is to place them an `internal-functions` file.
+
+## Use helper functions to fetch app images
+
+> New as of 0.4.0
+
+Dokku allows image tagging and deployment of tagged images. This means hard-coding the `$IMAGE` as `dokku/$APP` is no longer sufficient.
+
+Plugins should use `get_running_image_tag()` and `get_app_image_name()` as sourced from `common/functions`. See the [plugin triggers](/docs/development/plugin-triggers.md) doc for examples.
+
+> **Note:** This is only for plugins that are not `pre/post-build-*` plugins
+
+## Use `$DOCKER_BIN` instead of `docker` directly
+
+> New as of 0.17.5
+
+Certain systems may require a wrapper function around the `docker` binary for proper execution. Utilizing the `$DOCKER_BIN` environment variable when calling docker for those functions is preferred.
+
+```shell
+# good
+"$DOCKER_BIN" container run -d $IMAGE /bin/bash -e -c "$COMMAND"
+
+# bad
+docker run -d $IMAGE /bin/bash -e -c "$COMMAND"
+```
+
+## Include labels for all temporary containers and images
+
+> New as of 0.5.0
+
+As of 0.5.0, labels are used to help cleanup intermediate containers with `dokku cleanup`. Plugins that create containers and images should add the correct labels to the `build`, `commit`, and `run` docker commands.
+
+Note that where possible, a label `com.dokku.app-name=$APP` - where `$APP` is the name of the app - should also be included. This enables `dokku cleanup APP` to cleanup the specific containers for a given app.
+
+```shell
+# `docker build` example
+"$DOCKER_BIN" image build "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_BUILD_ARGS ...
+
+# `docker commit` example
+# Note that the arguments must be set as a local array
+# as arrays cannot be exported in shell
+local DOKKU_COMMIT_ARGS=("--change" "LABEL org.label-schema.schema-version=1.0" "--change" "LABEL org.label-schema.vendor=dokku" "--change" "LABEL $DOKKU_CONTAINER_LABEL=")
+"$DOCKER_BIN" container commit --change "LABEL com.dokku.app-name=$APP" "${DOKKU_COMMIT_ARGS[@]}" ...
+
+# `docker run` example
+"$DOCKER_BIN" container run "--label=com.dokku.app-name=${APP}" $DOKKU_GLOBAL_RUN_ARGS ...
+```
+
+## Copy files from the built image using `copy_from_image`
+
+Avoid copying files from running containers as these files may change over time. Instead copy files from the image built during the deploy process. This can be done via the `copy_from_image` helper function. This will correctly handle various corner cases in copying files from an image.
+
+```shell
+source "$PLUGIN_CORE_AVAILABLE_PATH/common/functions"
+
+local TMP_FILE=$(mktemp "/tmp/dokku-${DOKKU_PID}-${FUNCNAME[0]}.XXXXXX")
+trap "rm -rf '$TMP_FILE' >/dev/null" RETURN INT TERM
+
+local IMAGE_TAG="$(get_running_image_tag "$APP")"
+local IMAGE=$(get_deploying_app_image_name "$APP" "$IMAGE_TAG")
+copy_from_image "$IMAGE" "file-being-copied" "$TMP_FILE" 2>/dev/null
+```
+
+Files are copied from the `/app` directory - for images built via buildpacks - or `WORKDIR` - for images built via Dockerfile.
+
+## Avoid calling the `dokku` binary directly
+
+> New as of 0.6.0
+
+Plugins should **not** call the `dokku` binary directly from within plugins because clients using the `--app` argument are potentially broken when doing so.
+
+Plugins should instead source the `functions` file for a given plugin when attempting to call Dokku internal functions.

-# A few notes:
-
-- Remember to `chmod +x` your executable files
-- Always support `DOKKU_TRACE` as per the 2nd line of the above example
-- If your command depends on an application, include a check for whether that application exists (see the above example)
-- You must implement a `help` command, though you may leave it empty. Also, you must use commas (`,`) in the command syntax to support output in columns
-- Commands **should** be namespaced
-- As of 0.3.3, a catch-all should be implemented that exits with a `DOKKU_NOT_IMPLEMENTED_EXIT` code. This allows Dokku to output a `command not found` message.
-- Consider whether you want to include the `set -eo pipefail` option. Look at the following example :
-
-    ```shell
-    IMAGE=$(docker images | grep "user/repo" | awk '{print $3}')
-    if [[ -z $IMAGE ]]; then
-        dokku_log_fail "user/repo image not found... Did you run 'dokku plugin:install'?"
-    fi
-    ```
-
-  If `user/repo` doesn't exist, Dokku exits just before the `awk` command and the `dokku_log_fail` message will never go to   `STDOUT`. printed with echo. You would want to use `set -e` in this case.
-
-  Here is the `help` entry for `set`:
-  ```
-  help set
-    Options:
-      -e  Exit immediately if a command exits with a non-zero status.
-      -o option-name
-          pipefail     the return value of a pipeline is the status of
-                       the last command to exit with a non-zero status,
-                       or zero if no command exited with a non-zero status
-  ```
-- In the case that your plugin needs to set application configuration settings and you want to avoid having to restart (default Heroku-style behavior) these "internal" commands provide this functionality:
-
-  ```shell
-  dokku config:set --no-restart node-js-app KEY1=VALUE1 [KEY2=VALUE2 ...]
-  dokku config:unset --no-restart node-js-app KEY1 [KEY2 ...]

+Pull the dokku/dokku image:
+
+```shell
+docker pull dokku/dokku:0.19.2
+```
+
+Next, run the image.
+
+```shell
+docker run \

+  --volume /var/run/docker.sock:/var/run/docker.sock \
+  dokku/dokku:0.19.2
+```
+
+Dokku is run with the following options:
+
+- The global hostname is set to `dokku.me` on boot.
+- The container name is dokku.
+- Container SSH port 22 is exposed on the host as 3022.
+- Container HTTP port 80 is exposed on the host as 8080.
+- Container HTTPS port 443 is exposed on the host as 8443.
+- Data within the container is stored on the host within the `/var/lib/dokku` directory.
+- The docker socket is mounted into container
+
+Application repositories, plugin config, and plugin data is persisted to disk within the specified host directory for `/var/lib/dokku`.
+
+To install custom plugins, create a `plugin-list` file in the host's `/var/lib/dokku` directory. The plugins listed herein will be automatically installed by Dokku on container boot. This file should be the following format:
+
+```yaml
+plugin_name: repository_url
+```
+
+An example for installing the postgres and redis plugins follows:
+
+```yaml
+postgres: https://github.com/dokku/dokku-postgres.git
+redis: https://github.com/dokku/dokku-redis.git
+```
+
+To initialize ssh-keys within the container, use `docker exec` to enter the container and run the appropriate ssh-keys commands.
+
+```shell
+docker exec -it dokku bash
+```
+
+Please see the [user management documentation](/docs/deployment/user-management.md) for more information.
