+## Usage:
+
+### exerr
+
+ - see **mongoext/builder.go** for full info
+
+Short summary:
+ - An better error package with metadata, listener, api-output and error-traces
+ - Initialize with `exerr.Init()`
+ - *Never* return `err` direct, always use exerr.Wrap(err, "...") - add metadata where applicable
+ - at the end either Print(), Fatal() or Output() your error (print = stdout, fatal = panic, output = json API response)
+ - You can add listeners with exerr.RegisterListener(), and save the full errors to a db or smth
+
+### wmo
+
+ - A typed wrapper around the official mongo-go-driver
+ - Use `wmo.W[...](...)` to wrap the collections and type-ify them
+ - The new collections have all the usual methods, but types
+ - Also they have List() and Paginate() methods for paginated listings (witehr with a cursortoken or page/limit)
+ - Register additional hooks with `WithDecodeFunc`, `WithUnmarshalHook`, `WithMarshalHook`, `WithModifyingPipeline`, `WithModifyingPipelineFunc`
+ - List(), Paginate(), etc support filter interfaces
+   - Rule(s) of thumb: 
+     - filter the results in the filter interface
+     - sort the results in the sort function of the filter interface
+     - add joins ($lookup's) in the `WithModifyingPipelineFunc`/`WithModifyingPipeline`
+
+#### ginext
+
+ - A wrapper around gin-gonic/gin
+ - create the gin engine with `ginext.NewEngine`
+ - Add routes with `engine.Routes()...`
+   - `.Use(..)` adds a middleware
+   - `.Group(..)` adds a group
+   - `.Get().Handle(..)` adds a handler
+ - Handler return values (in contract to ginext) - values implement the `ginext.HTTPResponse` interface
+ - Every handler starts with something like:
+```go 
+func (handler Handler) CommunityMetricsValues(pctx ginext.PreContext) ginext.HTTPResponse {
+    type communityURI struct {
+        Version     string             `uri:"version"`
+        CommunityID models.CommunityID `uri:"cid"`
+    }
+    type body struct {
+        UserID  models.UserID  `json:"userID"`
+        EventID models.EventID `json:"eventID"`
+    }
+
+    var u uri
+    var b body
+    ctx, gctx, httpErr := pctx.URI(&u).Body(&b).Start() // can have more unmarshaller, like header, form, etc
+    if httpErr != nil {
+    	return *httpErr
+    }
+    defer ctx.Cancel()
+
+    // do stuff
+}
+```
+
+#### sq
