+## load
+
+Load and evaluate a file, resetting repl state beforehand if optional RESET is
+true.
+
+
+### Basic syntax
+
+To load a separate pact or repl file, call
+
+```pact
+(load "my-file.pact")
+```
+
+If the load requires resetting repl state, use
+
+```pact
+(load "my-file.pact" true)
+```
+
+
+## Arguments
+
+Use the following argument when using the `load` Pact function.
+
+| Argument | Type     | Description                                                  |
+|----------|----------|--------------------------------------------------------------|
+| File     | string   | The file to load                                             |
+| Reset    | bool     | (Optional) Reset the repl state before loading               |
+
+### Return value
+
+`load` returns the unit value `()`
+
+### Example
+
+The following example demonstrates how to use the `load` function to set "my-key" and "admin-key" as the current transaction signing keys in a Pact REPL:
+
+```pact
+pact> (load "hello-world.repl")
+"Hello pact!"
+```
