-// Package mapstructure exposes functionality to convert an arbitrary
-// map[string]interface{} into a native Go structure.
+// Package mapstructure exposes functionality to convert one arbitrary
+// Go type into another, typically to convert a map[string]interface{}
+// into a native Go structure.
 //
 // The Go structure can be arbitrarily complex, containing slices,
 // other structs, etc. and the decoder will properly decode nested
 // maps and so on into the proper structures in the native Go struct.
 // See the examples to see what the decoder is capable of.
+//
+// The simplest function to start with is Decode.
+//
+// Field Tags
+//
+// When decoding to a struct, mapstructure will use the field name by
+// default to perform the mapping. For example, if a struct has a field
+// "Username" then mapstructure will look for a key in the source value
+// of "username" (case insensitive).
+//
+//     type User struct {
+//         Username string
+//     }
+//
+// You can change the behavior of mapstructure by using struct tags.
+// The default struct tag that mapstructure looks for is "mapstructure"
+// but you can customize it using DecoderConfig.
+//
+// Renaming Fields
+//
+// To rename the key that mapstructure looks for, use the "mapstructure"
+// tag and set a value directly. For example, to change the "username" example
+// above to "user":
+//
+//     type User struct {
+//         Username string `mapstructure:"user"`
+//     }
+//
+// Embedded Structs and Squashing
+//
+// Embedded structs are treated as if they're another field with that name.
+// By default, the two structs below are equivalent when decoding with
+// mapstructure:
+//
+//     type Person struct {
+//         Name string
+//     }
+//
+//     type Friend struct {
+//         Person
+//     }
+//
+//     type Friend struct {
+//         Person Person
+//     }
+//
+// This would require an input that looks like below:
+//
+//     map[string]interface{}{
+//         "person": map[string]interface{}{"name": "alice"},
+//     }
+//
+// If your "person" value is NOT nested, then you can append ",squash" to
+// your tag value and mapstructure will treat it as if the embedded struct
+// were part of the struct directly. Example:
+//
+//     type Friend struct {
+//         Person `mapstructure:",squash"`
+//     }
+//
+// Now the following input would be accepted:
+//
+//     map[string]interface{}{
+//         "name": "alice",
+//     }
+//
+// When decoding from a struct to a map, the squash tag squashes the struct
+// fields into a single map. Using the example structs from above:
+//
+//     Friend{Person: Person{Name: "alice"}}
+//
+// Will be decoded into a map:
+//
+//     map[string]interface{}{
+//         "name": "alice",
+//     }
+//
+// DecoderConfig has a field that changes the behavior of mapstructure
+// to always squash embedded structs.
+//
+// Remainder Values
+//
+// If there are any unmapped keys in the source value, mapstructure by
+// default will silently ignore them. You can error by setting ErrorUnused
+// in DecoderConfig. If you're using Metadata you can also maintain a slice
+// of the unused keys.
+//
+// You can also use the ",remain" suffix on your tag to collect all unused
+// values in a map. The field with this tag MUST be a map type and should
+// probably be a "map[string]interface{}" or "map[interface{}]interface{}".
+// See example below:
+//
+//     type Friend struct {
+//         Name  string
+//         Other map[string]interface{} `mapstructure:",remain"`
+//     }
+//
+// Given the input below, Other would be populated with the other
+// values that weren't used (everything but "name"):
+//
+//     map[string]interface{}{
+//         "name":    "bob",
+//         "address": "123 Maple St.",
+//     }
+//
+// Omit Empty Values
+//
+// When decoding from a struct to any other value, you may use the
+// ",omitempty" suffix on your tag to omit that value if it equates to
+// the zero value. The zero value of all types is specified in the Go
+// specification.
+//
+// For example, the zero type of a numeric type is zero ("0"). If the struct
+// field value is zero and a numeric type, the field is empty, and it won't
+// be encoded into the destination type.
+//
+//     type Source {
+//         Age int `mapstructure:",omitempty"`

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+## Development status
+
+**ℹ️ Consider go-toml v2!**
+
+The next version of go-toml is in [active development][v2-dev], and
+[nearing completion][v2-map].
+
+Though technically in beta, v2 is already more tested, [fixes bugs][v1-bugs],
+and [much faster][v2-bench]. If you only need reading and writing TOML documents
+(majority of cases), those features are implemented and the API unlikely to
+change.
+
+The remaining features (Document structure editing and tooling) will be added
+shortly. While pull-requests are welcome on v1, no active development is
+expected on it. When v2.0.0 is released, v1 will be deprecated.

+The maximum capacity of a QR Code varies according to the content encoded and the error recovery level. The maximum capacity is 2,953 bytes, 4,296 alphanumeric characters, 7,089 numeric digits, or a combination of these.
+
+## Borderless QR Codes
+
+To aid QR Code reading software, QR codes have a built in whitespace border.
+
+If you know what you're doing, and don't want a border, see https://gist.github.com/skip2/7e3d8a82f5317df9be437f8ec8ec0b7d for how to do it. It's still recommended you include a border manually.

-After executing:

+So instead of doing that let's pass a Viper instance to the constructor that represents a subset of the configuration:

 ## 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.
+
+You can vote for case sensitivity by filling out this feedback form: https://forms.gle/R6faU74qPRPAzchZ9
+
+### Is it safe to concurrently read and write to a viper?
+
+No, you will need to synchronize access to the viper yourself (for example by using the `sync` package). Concurrent reads and writes can cause a panic.
+

+# 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.
