 Routers can be configured via options. The following options are available for the `reitit.core/router`:
 
-| key          | description
-|--------------|-------------
-| `:path`          | Base-path for routes
-| `:routes`        | Initial resolved routes (default `[]`)
-| `:data`          | Initial route data (default `{}`)
-| `:spec`          | clojure.spec definition for a route data, see `reitit.spec` on how to use this
-| `:syntax`        | Path-parameter syntax as keyword or set of keywords (default #{:bracket :colon})
-| `:expand`        | Function of `arg opts => data` to expand route arg to route data (default `reitit.core/expand`)
-| `:coerce`        | Function of `route opts => route` to coerce resolved route, can throw or return `nil`
-| `:meta-merge-fn` | Function which follows the signature of `meta-merge.core/meta-merge`, useful for when you want to have more control over the meta merging
-| `:compile`       | Function of `route opts => result` to compile a route handler
-| `:validate`      | Function of `routes opts => ()` to validate route (data) via side-effects
-| `:conflicts`     | Function of `{route #{route}} => ()` to handle conflicting routes
-| `:exception`     | Function of `Exception => Exception ` to handle creation time exceptions (default `reitit.exception/exception`)
-| `:router`        | Function of `routes opts => router` to override the actual router implementation
