 	Nette HTTP client
 </h1>
 
+<h2>ABANDONED</h2>
+
+<p>
+     Over time I found the PSR HTTP client really annoying to work with.
+     Lot of interfaces where one would be enough. Lot of boilerplate.
+     No way of configuring transport and certificates for various services which do not
+     work well with default config. Just use symfony/http-client directly.
+     I will eventually add http debug panel to Tracy which will work universally.
