 ### Packages
 
@@ -182,16 +190,53 @@ Most people just want to use binaries, you can find those [here](https://github.
 If you really want to build from source, follow these instructions:
 Go 1.17+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed.
 
+Building the binary with **all** the bridges enabled needs about 3GB RAM to compile.
+You can reduce this memory requirement to 0,5GB RAM by adding the `nomsteams` tag if you don't need/use the Microsoft Teams bridge.
+
+Matterbridge can be build without gcc/c-compiler: If you're running on windows first run `set CGO_ENABLED=0` on other platforms you prepend `CGO_ENABLED=0` to the `go build` command. (eg `CGO_ENABLED=0 go install github.com/42wim/matterbridge`)
+
 To install the latest stable run:
 
 ```bash
-go install github.com/42wim/matterbridge@v1.24.1
+go install github.com/42wim/matterbridge
 ```
 
 To install the latest dev run:
 
 ```bash
-go install github.com/42wim/matterbridge@latest
+go install github.com/42wim/matterbridge@master
+```
+
+To install the latest stable run without msteams or zulip bridge:
+
+```bash
+go install -tags nomsteams,nozulip github.com/42wim/matterbridge
+```
+
+You should now have matterbridge binary in the ~/go/bin directory:
+
+```bash
+$ ls ~/go/bin/
+matterbridge
+```
+
+## Building with whatsapp (beta) multidevice support
+
+Because the library we use for Whatsapp multidevice support includes a GPL3 library we can not provide you binaries.
+(as this would require the Matterbridge to change it license to GPL)
+
+Matterbridge can be build without gcc/c-compiler: If you're running on windows first run `set CGO_ENABLED=0` on other platforms you prepend `CGO_ENABLED=0` to the `go build` command. (eg `CGO_ENABLED=0 go install github.com/42wim/matterbridge`)
+
+So this means you have to build it yourself using the instructions below:
+
+```bash
+go install -tags whatsappmulti github.com/42wim/matterbridge@master
+```
+
+If you're low on memory and don't need msteams:

+
+This library implements the edwards25519 elliptic curve, exposing the necessary APIs to build a wide array of higher-level primitives.
+Read the docs at [pkg.go.dev/filippo.io/edwards25519](https://pkg.go.dev/filippo.io/edwards25519).
+
+The code is originally derived from Adam Langley's internal implementation in the Go standard library, and includes George Tankersley's [performance improvements](https://golang.org/cl/71950). It was then further developed by Henry de Valence for use in ristretto255.
+
+Most users don't need this package, and should instead use `crypto/ed25519` for signatures, `golang.org/x/crypto/curve25519` for Diffie-Hellman, or `github.com/gtank/ristretto255` for prime order group logic. However, for anyone currently using a fork of `crypto/ed25519/internal/edwards25519` or `github.com/agl/edwards25519`, this package should be a safer, faster, and more powerful alternative.
+
+Since this package is meant to curb proliferation of edwards25519 implementations in the Go ecosystem, it welcomes requests for new APIs or reviewable performance improvements.

 Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
 
-To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
-
-* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
-* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
-* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
-* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
-* When you're done, you will want to halt or destroy the Vagrant boxes.
-
-Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
-
-Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).

+# graphql-go [![Sourcegraph](https://sourcegraph.com/github.com/graph-gophers/graphql-go/-/badge.svg)](https://sourcegraph.com/github.com/graph-gophers/graphql-go?badge) [![Build Status](https://graph-gophers.semaphoreci.com/badges/graphql-go/branches/master.svg?style=shields)](https://graph-gophers.semaphoreci.com/projects/graphql-go) [![GoDoc](https://godoc.org/github.com/graph-gophers/graphql-go?status.svg)](https://godoc.org/github.com/graph-gophers/graphql-go)
+
+<p align="center"><img src="docs/img/logo.png" width="300"></p>
+
+The goal of this project is to provide full support of the [GraphQL draft specification](https://facebook.github.io/graphql/draft) with a set of idiomatic, easy to use Go packages.
+
+While still under heavy development (`internal` APIs are almost certainly subject to change), this library is
+safe for production use.
+
+## Features
+
+- minimal API
+- support for `context.Context`
+- support for the `OpenTracing` standard
+- schema type-checking against resolvers
+- resolvers are matched to the schema based on method sets (can resolve a GraphQL schema with a Go interface or Go struct).
+- handles panics in resolvers
+- parallel execution of resolvers
+- subscriptions
+   - [sample WS transport](https://github.com/graph-gophers/graphql-transport-ws)
+
+## Roadmap
+
+We're trying out the GitHub Project feature to manage `graphql-go`'s [development roadmap](https://github.com/graph-gophers/graphql-go/projects/1).
+Feedback is welcome and appreciated.
+
+## (Some) Documentation
+
+### Basic Sample
+
+```go
+package main
+
+import (
+        "log"
+        "net/http"
+
+        graphql "github.com/graph-gophers/graphql-go"
+        "github.com/graph-gophers/graphql-go/relay"
+)
+
+type query struct{}
+
+func (_ *query) Hello() string { return "Hello, world!" }
+
+func main() {
+        s := `
+                type Query {
+                        hello: String!
+                }
+        `
+        schema := graphql.MustParseSchema(s, &query{})
+        http.Handle("/query", &relay.Handler{Schema: schema})
+        log.Fatal(http.ListenAndServe(":8080", nil))
+}
+```
+
+To test:
+	    
+```sh
+curl -XPOST -d '{"query": "{ hello }"}' localhost:8080/query
+```
+
+### Resolvers
+
+A resolver must have one method or field for each field of the GraphQL type it resolves. The method or field name has to be [exported](https://golang.org/ref/spec#Exported_identifiers) and match the schema's field's name in a non-case-sensitive way.
+You can use struct fields as resolvers by using `SchemaOpt: UseFieldResolvers()`. For example,
+```
+opts := []graphql.SchemaOpt{graphql.UseFieldResolvers()}
+schema := graphql.MustParseSchema(s, &query{}, opts...)
+```   
+
+When using `UseFieldResolvers` schema option, a struct field will be used *only* when:
+- there is no method for a struct field
+- a struct field does not implement an interface method
+- a struct field does not have arguments
+
+The method has up to two arguments:
+
+- Optional `context.Context` argument.
+- Mandatory `*struct { ... }` argument if the corresponding GraphQL field has arguments. The names of the struct fields have to be [exported](https://golang.org/ref/spec#Exported_identifiers) and have to match the names of the GraphQL arguments in a non-case-sensitive way.
+
+The method has up to two results:
+
+- The GraphQL field's value as determined by the resolver.
+- Optional `error` result.
+
+Example for a simple resolver method:
+
+```go
+func (r *helloWorldResolver) Hello() string {
+	return "Hello world!"
+}
+```
+
+The following signature is also allowed:
+
+```go
+func (r *helloWorldResolver) Hello(ctx context.Context) (string, error) {
+	return "Hello world!", nil
+}
+```
+
+### Schema Options
+
+- `UseStringDescriptions()` enables the usage of double quoted and triple quoted. When this is not enabled, comments are parsed as descriptions instead.
+- `UseFieldResolvers()` specifies whether to use struct field resolvers.
+- `MaxDepth(n int)` specifies the maximum field nesting depth in a query. The default is 0 which disables max depth checking.
+- `MaxParallelism(n int)` specifies the maximum number of resolvers per request allowed to run in parallel. The default is 10.
+- `Tracer(tracer trace.Tracer)` is used to trace queries and fields. It defaults to `trace.OpenTracingTracer`.
+- `ValidationTracer(tracer trace.ValidationTracer)` is used to trace validation errors. It defaults to `trace.NoopValidationTracer`.
+- `Logger(logger log.Logger)` is used to log panics during query execution. It defaults to `exec.DefaultLogger`.
+- `PanicHandler(panicHandler errors.PanicHandler)` is used to transform panics into errors during query execution. It defaults to `errors.DefaultPanicHandler`.
+- `DisableIntrospection()` disables introspection queries.
+
+### Custom Errors
+
+Errors returned by resolvers can include custom extensions by implementing the `ResolverError` interface:
+
+```go
+type ResolverError interface {
+	error
+	Extensions() map[string]interface{}
+}
+```
+
+Example of a simple custom error:
+
+```go
+type droidNotFoundError struct {
+	Code    string `json:"code"`
+	Message string `json:"message"`
+}
+
+func (e droidNotFoundError) Error() string {
+	return fmt.Sprintf("error [%s]: %s", e.Code, e.Message)
+}
+
+func (e droidNotFoundError) Extensions() map[string]interface{} {
+	return map[string]interface{}{
+		"code":    e.Code,
+		"message": e.Message,
+	}
+}
+```
+
+Which could produce a GraphQL error such as:
+
+```go
+{
+  "errors": [
+    {
+      "message": "error [NotFound]: This is not the droid you are looking for",
+      "path": [
+        "droid"
+      ],
+      "extensions": {
+        "code": "NotFound",
+        "message": "This is not the droid you are looking for"
+      }
+    }
+  ],
+  "data": null
+}
+```
