 ## 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:
+
+```shell
+config_set --no-restart node-js-app KEY1=VALUE1 [KEY2=VALUE2 ...]
+config_unset --no-restart node-js-app KEY1 [KEY2 ...]
+```
+
+## 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" 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
+"$DOCKER_BIN" build "--label=com.dokku.app-name=${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" commit --change "LABEL com.dokku.app-name=$APP" "${DOKKU_COMMIT_ARGS[@]}" ...
+
+# `docker run` example
+"$DOCKER_BIN" run "--label=com.dokku.app-name=${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 ...]
-  ```
-- If you want to allow other plugins access to (some of) your plugin's functionality, you can expose this by including a `functions` file in your plugin for others to source
-  - You should consider all functions in that file to be publicly accessible by other plugins
-  - Any functions you want to keep private should reside in your plugin's `trigger/` or `commands/` directories
-- As of 0.4.0, Dokku allows image tagging and deployment of tagged images

+Pull the dokku/dokku image:
+
+```shell
+docker pull dokku/dokku:0.18.2
+```
+
+Next, run the image.
+
+```shell
+docker run \
+  --env DOKKU_HOSTNAME=dokku.me \
+  --name dokku \
+  --publish 3022:22 \

+  --volume /var/run/docker.sock:/var/run/docker.sock \
+  dokku/dokku:0.18.2
+```
+
+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.

+
+## Trace Mode
+
+By default, Dokku will constrain the amount of output displayed for any given command run. The verbosity of output can be increased by enabling trace mode. Trace mode will turn on the `set -x` flag for bash plugins, while other plugins are free to respect the environment variable `DOKKU_TRACE` and log differently as approprate. Trace mode can be useful to see _where_ plugins are running commands that would otherwise be unexpected.

 In Dokku 0.5.0, port proxying was decoupled from the `nginx-vhosts` plugin into the proxy plugin. Dokku 0.6.0 introduced the ability to map host ports to specific container ports. In the future this will allow other proxy software - such as HAProxy or Caddy - to be used in place of nginx.
 
 ## Usage
 
+> Warning: Mapping alternative ports may conflict with the active firewall installed on your server or hosting provider. Such software includes - but is not limited to - AWS Security Groups, iptables, and UFW. Please consult the documentation for those softwares as applicable.
