+These templates are used with [abi-gen](https://github.com/0xProject/0x-monorepo/tree/development/packages/abi-gen).
+
+To successfully compile the generated TypeScript contract wrappers, you must:
+
+*   Install the packages on which the main contract template directly depends: `yarn add @0x/base-contract @0x/sol-compiler @0x/utils @0x/web3-wrapper ethereum-types ethers lodash`
+*   Install the packages on which the main contract template *in*directly depends: `yarn add @types/lodash`
+*   Ensure that your TypeScript configuration includes the following:
+
+```
+"compilerOptions": {
+  "lib": ["ES2015"],
+  "typeRoots": [
+    "node_modules/@0x/typescript-typings/types",
