+# Command-Line Interface Basics
+
+CLI is the primary method of **inrecacting with Gradle**.
+Executing Gradle on the command line conforms to the following structure:
+```bash
+gradle [taskName...] [--option-name...]
+```
+
+Options are allowed _before_ and _after_ task names:
+```bash
+gradle [--option-name...] [taskName...]
+```
+
+Multiple tasks should be separated by space:
+```bash
+gradle [taskName1 taskName2...] [--option-name...]
+```
+
+Options that enable behavior have long-form options with inverses specified with `--no-`:
+```bash
+gradle [...] --build-cache
+gradle [...] --no-build-cache
+```
+
+Some long-form options have short-options equivalents:
+```bash
+gradle --help
+gradle -h
+```
+
+## Command-Line usage
+
+### Executing tasks
+
+To execute a task called `taskName` on the root project:
+```bash
+$ gradle :taskName
+```
+This will run the single task `taskName` and all of its dependencies.
+
+### Specify options for tasks
+
+To pass an option to a task, prefix the option with `--` after the task name:
+```bash
+$ gradle taskName --exampleOption=exampleValue
+```
+
