 # GoSh!
 A Shell made in Go, for fun  
 ## Features
-At the moment, there isn't much features.  
-I'm planning to add more features later (like syntax hilighting, a history file and a RC file, etc...).  
+- Display Working Directory
+- History file wich you can browse for past commands
+- Some colors
+- Config file
+- PTY support for interactive commands
+I'm planning to add more features later (like syntax hilighting, etc...).  
 I'm also learning Go by doing this project.  
 You can expect breaking changes (or code), the problem has a workaround in the commit message.  
-If not, the issue will be fixed soon (in case of a typo for example)
+If not, the issue will be fixed soon (in case of a typo for example)  
+
+## Installation
+You can grab the binaries for your system and architecture, or build it yourself
+To build it, clone the repository, cd into it and run  
+`go build -o bin/GoSH`  
+To test the shell and see if it suits you.  
+If everything works, then move the binary to a place inside your path.  
+
+To directly install it with the Go toolchain, just use  
+`go install`  
+This will build and place the binary inside your `$HOME/go/bin` folder.  
+Add this folder to your path and you are good to go !  
+
+## Usage
+To use the program, just invoke it with `GoSH`  
+~~If you see a message about a config file, create `~/.config/gosh/gosh_config.toml` and populate it with the defaults written inside this repo -> [here](/defaults.toml).~~  
+To change config parameter on the fly, use the `set` builtin.  
+Currently, `set` has a limited amount of configuration options and need to have a valid config file to write to.  
+To change the color of the prompt use `set color <color>`  
+All the avalable colors :
+  - black
+  - red
+  - purple
+  - cyan
+  - white
+  - green
+  - yellow
+  - blue   
+
+You can change the history size with `set history_size <int>`  
+You can change the prompt with `set prompt <promp>`  
+Here is some exemple of prompts :  
+  - `[{dir}] > `
+  - `["Hello World"] $ `
+  - `"Hello" `  
+You can use all "console colors", listed [here](https://gist.github.com/kamito/704813)  
+
+## Know Issues
+Currently there is a number of known or unkwown issues.  
+We can list the fact that interactive programs, like SSH or VIM work partialy.  
+The config has to be manualy created and populated.  
+Also pipes aren't supported yet, so no `ls | grep "thing"`  
+PTY currently don't support signals like 'Ctrl+C' so don't use vim, nano nor nvim for exemple.  
+
+## ToDo
+- Tab completion (for cd)
