 # bin
 Manages bin files downloaded from different sources
 
+## Rationale
+
+`bin` started as an idea given the popularity of single binary releases due to the surge of  languages like 
+Go, Rust, Deno, etc whih can easily produce dynamically and statically compiled binarines. 
+
+I found myself downloading binaries (or tarballs) directly from VCS (Github mostly) and then it was hard
+to keep control and update such dependencies whenever a new version was released. So, with the objective 
+to solve that problem and also looking for something that will allow me to get the latest releases, I created `bin`.
+In addition to that, I was also looking for something that doesn't require `sudo` or `root` privileges to install 
+these binaries as downloading, making them executable and storing it somewhere in your PATH would be sufficient.
+
+After I finished the first MVP, a friend pointed out that [brew](brew.sh) was now supported in linux which almost 
+made me abandon the project. After checking out brew (never been an osx user), I found it a bit bloated and seems
+to be doing way more than what I'm actually needing. So, I've decided to continue `bin` and hopefully add more features
+that could result useful to somewhere else. 
+
+If you find `bin` helpful and you have any ideas or suggestions, please create an issue here or send a PR and I'll 
+be more than happy to brainstrom about possibilities.

 ## Usage
 
 ```
-bin install <repo> [PATH] # Downloads the latest binary and makes it executable 
-bin update [BIN]... # Scans binaries and prompts for update
+bin install <repo> [path] # Downloads the latest binary and makes it executable 
+bin update [bin]... # Scans binaries and prompts for update
 bin ls # List current binaries and it's versions
 bin remove <bin>... # Deletes one or more binaries
+bin purge # Removes from the DB missing binaries
 ```
