+# Fe
+
+#### **`create() → (Fe)`**
+
+Creates a new `Fe` struct with the following defaults.
+
+```solidity
+Fe({
+    compilerPath: "fe",
+    filePath: "",
+    emitOptions: "",
+    outputDir: "",
+    overwrite: false
+});
+```
+
+> Notice: The `filePath` is the only required field, if it is empty, `.build` and `.toCommand`
+> will revert.
+
+#### **`build(Fe self) → (bytes)`**
+
+Builds a binary file from a `.fe` file.
+
+#### **`toCommand(Fe self) → (Command)`**
+
+Converts the `Fe` struct into a `Command` struct.
+
+#### **`setCompilerPath(Fe self, string compilerPath) → (Fe)`**
+
+Overwrites the compiler path.
+
+#### **`setFilePath(Fe self, string filePath) → (Fe)`**
+
+Overwrites the file path.
+
+#### **`setOutputDir(Fe self, string outputDir) → (Fe)`**
+
+Overwrites the default artifacts directory.
+
+#### **`setEmitOptions(Fe memory self, string memory emitOptions) → (Fe)`**
+
+Overwrites the default emit options. `abi,bytecode` is the default value. Use `fe build --help` to
+get all the other possible values.
+
+#### **`setOverwrite(Fe memory self, bool overwrite) → (Fe)`**
+
+Sets the build command overwrite flag. If `true` the contents of `outputDir` will be overwritten.
