+### Location
+
+Location syntax is similar to [Nginx](https://nginx.org/r/location), but here you provide a list of location pattern.
+
+Matching is after decoding the text encoded in the “%XX” form.
+
+Syntax: `[ = | ^ | ~ ] URI`.
+
+There are three type: `=`(equal), `^`(startsWith) and `~`(regex).
+
+**There is a space between type and URI.**
+
+When no type is provided and uri is starts with `/`, type will be `^`(startsWith).
+
+*Why the hell a URI will start without `/`??*
+
+For example:
+
+```toml
+location = ["/public", "~ /static/*.(gif|jpg|jpeg)"]
+```
+
+### Rewrite
+
+Rewrite syntax is similar to [Nginx](https://nginx.org/r/rewrite), but here you provide a list of rewrite pattern.
+
+Matching is after decoding the text encoded in the “%XX” form.
+
+Syntax: `rewrite-regex URI [flag]`.
+
+An optional `flag` parameter can be one of:
+- `last`: The default one, stops processing the current set of rewrite and starts a search for a new location matching the changed URI;
+- `break`: stops processing the current rewrite rule and start to search next.
+
+For example:
+
+```toml
+rewrite = ["^/(.*) /service2/$1 last"]
+```
