 A small program that allows writing rules to determine which browser to lauch based on the URL
 
-Tested on an Ubuntu and Pop_OS! system but should work on anything that supports xdg
+This is tested on an Ubuntu system but should work on anything that supports xdg
 
 ## Configuration
 
-When launched, configuration will be read first from the `-config` option, if provided, then from `$XDG_CONFIG_HOME/browser-ruler/config.hcl`, if found, and then from `$HOME/.browser-ruler.hcl`. If none of these are found, it will panic and ask you to provide it some configuration.
+There is no configuration, persay. Intead, the code must be updated.
 
-Config files are in the HCL config language with a schema defined below.
+Edit `rules.go` and edit the list of `BrowserRules` in a similar fashion as the example and then run `make install` again.
 
-```hcl
+You can use any rule functions found in `main.go` and any browsers found in `browsers.go`.
-default_browser_cmd = list(string)
 
-rule [label] {
+There is also a Python version as `browser_ruler.py`. To use that instead, you can edit that and then update the Makefile to make the `BIN` variable `BIN = browser_ruler.py`.
-    browser_cmd = list(string)
-    match = string
-}
-```
-
-To see some detailed samples, check out `sample-config.hcl`.
-
-### Writing a MatchFunc
-
-The `match` expression in the config should be a `MatchFunc`. This can done by using any of the helper methods available:
-
-```go
-// accepts any number of hostnames and returns a match function that matches the hostname against any of them
-matchHostname(...string) MatchFunc
-// accepts any number of regexps and returns a match function that matches the hostname against any of them
-matchHostRegexp(...string) MatchFunc
-// accepts any number of regexps and returns a match function that matches the full url string against any of them
-matchRegexp(...string) MatchFunc
-// accepts any number of MatchFuncs and returns a new match function that matches against any of them
-matchAny(...MatchFunc) MatchFunc
-```
-
-If you want more flexibility, you can write your own using the [`expr`](https://github.com/antonmedv/expr) language. Generally, this language gives you the power to write an expression that evaluates to a boolean using exposed variables. Additonally, a helper exists to convert a `bool` value into a `MatchFunc`. For example:
-
-```
-MatchFunc(hostname endsWith "google.com")
-```
-
-The following variables are avaiable for building custom match expressions.
-
-```
-hostname: the requested URL hostname
-fullUrl: the full string of the requested URL
-url: the Go url.URL struct requested URL
-MatchFunc(bool) MatchFunc: constructs a match function from a bool value
-```
