+Todo.sh add-ons let you add new todo.sh actions or change (override) default actions.  Visit the [[Todo.sh Add-on Directory]] to find browse available add-ons.
+
+## Installing Add-ons
+
+Add-ons can be installed into the `$HOME/.todo.actions.d` directory or any other directory configured via `$TODO_ACTIONS_DIR`.
+
+Create this directory with the following bash shell commands:
+
+```bash
+$ mkdir -p ~/.todo.actions.d
+```
+
+You must name add-ons after the action you want to add or override. For example, create a new "review" action by installing an add-on to `.todo.actions.d/review`.
+
+After installing the add-on, you must make it executable.
+
+For example:
+
+```bash
+$ chmod +x ~/.todo.actions.d/review
+```
+
+Use the new or overridden action the normal todo.sh way.
+
+For example:
+
+```bash
+$ todo.sh review
+```
+
+You can force todo.sh to use a default action instead of an overridden action by prefixing the action's name with the word, "command".
+
+For example:
+
+```bash
+$ todo.sh command ls
+```
+
+## Creating Add-ons
+
+Add-ons may be written in any programming language your operating system supports. The first command-line argument to the add-on will be the action called or the word "usage"; the remaining arguments, if any, will be those provided by the user. For example:
+
+```bash
+$ todo.sh _dummy_action foo bar
+First argument: _dummy_action
+Remaining arguments:
+	* foo
+	* bar
+```
+
+If the first argument is _usage_, you should provide a short usage message that will be displayed when the user calls `todo.sh -h`.
+
+Todo.sh will also provide your script with several environmental variables including the following documented in todo.sh's usage message:
+
+* `TODOTXT_PRESERVE_LINE_NUMBERS`
+* `TODOTXT_VERBOSE`
+* `TODOTXT_PLAIN`
+* `TODOTXT_AUTO_ARCHIVE`
+* `TODOTXT_FORCE`
+* `TODOTXT_DATE_ON_ADD`
+
+and the following environmental variables not documented in the usage message:
+
+* `TODO_SH` - name of the todo.sh script, use in the usage message
+* `TODO_FULL_SH` - complete path to calling todo.sh script, use for invoking todo.sh
+* `TODOTXT_CFG_FILE` - complete path to user's todo.sh configuration file
+* `TODO_DIR` - complete path to the todo.txt file
+
+## [[Creating Add-ons: Examples]]
+
+## Aliasing Add-ons
+
+You may want to allow short aliases for those new commands (e.g. "pv" as alias for "projectview")
+
+There is a small issue if you simply duplicate or symlink the add-on file: the corresponding help snippet will be duplicated as well in the output of the todo.sh help command. To avoid that, you can create aliases by creating short add-ons such as this example (replace `projectview` by the command you want to call with your alias):
+
+```bash
+#!/bin/bash
+[ "$1" = "usage" ] && exit 0
+shift
+"$TODO_FULL_SH" projectview "$@"
+```
