-After executing:
+We could pass the cache name to a module (eg. `NewCache("cache1")`),

-```go
-subv := viper.Sub("app.cache1")
-```
+So instead of doing that let's pass a Viper instance to the constructor that represents a subset of the configuration:
 
-`subv` represents:

+Internally, the `NewCache` function can address `max-items` and `item-size` keys directly:

-
-```go
-cfg1 := viper.Sub("app.cache1")
-cache1 := NewCache(cfg1)
+The resulting code is easy to test, since it's decoupled from the main config structure,
+and easier to reuse (for the same reason).

 ## Q & A
 
-Q: Why is it called “Viper”?
+### Why is it called “Viper”?
 
 A: Viper is designed to be a [companion](http://en.wikipedia.org/wiki/Viper_(G.I._Joe))
 to [Cobra](https://github.com/spf13/cobra). While both can operate completely
 independently, together they make a powerful pair to handle much of your
 application foundation needs.
 
-Q: Why is it called “Cobra”?
+### Why is it called “Cobra”?
+
+Is there a better name for a [commander](http://en.wikipedia.org/wiki/Cobra_Commander)?
+
+### Does Viper support case sensitive keys?
+
+**tl;dr:** No.
+
+Viper merges configuration from various sources, many of which are either case insensitive or uses different casing than the rest of the sources (eg. env vars).
+In order to provide the best experience when using multiple sources, the decision has been made to make all keys case insensitive.
+
+There has been several attempts to implement case sensitivity, but unfortunately it's not that trivial. We might take a stab at implementing it in [Viper v2](https://github.com/spf13/viper/issues/772), but despite the initial noise, it does not seem to be requested that much.

+# Troubleshooting
+
+## Unmarshaling doesn't work
+
+The most common reason for this issue is improper use of struct tags (eg. `yaml` or `json`). Viper uses [github.com/mitchellh/mapstructure](https://github.com/mitchellh/mapstructure) under the hood for unmarshaling values which uses `mapstructure` tags by default. Please refer to the library's documentation for using other struct tags.
+
+## Cannot find package
+
+Viper installation seems to fail a lot lately with the following (or a similar) error:
+
+```
+cannot find package "github.com/hashicorp/hcl/tree/hcl1" in any of:
+/usr/local/Cellar/go/1.15.7_1/libexec/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOROOT)
+/Users/user/go/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOPATH)
+```
+
+As the error message suggests, Go tries to look up dependencies in `GOPATH` mode (as it's commonly called) from the `GOPATH`.
+Viper opted to use [Go Modules](https://github.com/golang/go/wiki/Modules) to manage its dependencies. While in many cases the two methods are interchangeable, once a dependency releases new (major) versions, `GOPATH` mode is no longer able to decide which version to use, so it'll either use one that's already present or pick a version (usually the `master` branch).
+
+The solution is easy: switch to using Go Modules.
+Please refer to the [wiki](https://github.com/golang/go/wiki/Modules) on how to do that.
