+### Verifying Dependency Version
+
+Some project requirements need to respect a version constraint. This can be enforced in a recipe by accessing the [`deps_cpp_info`](https://docs.conan.io/en/latest/reference/conanfile/attributes.html#deps-cpp-info) attribute. 
+An exaple of this can be found in the [spdlog recipe](https://github.com/conan-io/conan-center-index/blob/9618f31c4d9b4da5d06f905befe9691cf105a1fc/recipes/spdlog/all/conanfile.py#L92-L94).
+
+```py
+if tools.Version(self.deps_cpp_info["liba"].version) < "7":
+    raise ConanInvalidConfiguration(f"The project {self.name}/{self.version} requires liba > 7.x")
+```
+
+In Conan version 1.x this needs to be done in the `build` method, in future release is should be done in the `validate` method.
+
+### Verifying Dependency Options
+
+Certain projects are dependant on the configuration (a.k.a options) of a dependency. This can be enforced in a recipe by accessing the [`options`](https://docs.conan.io/en/latest/reference/conanfile/attributes.html#options) attribute.
+An example of this can be found in the [kealib recipe](https://github.com/conan-io/conan-center-index/blob/9618f31c4d9b4da5d06f905befe9691cf105a1fc/recipes/kealib/all/conanfile.py#L44-L46).
+
+```py
+    def validate(self):
+        if not self.options["liba"].enable_feature:
+            raise ConanInvalidConfiguration(f"The project {self.name}/{self.version} requires liba.enable_feature=True.")
+```
