 ## Adding a dependency ##

-rclone uses the [go
-modules](https://tip.golang.org/cmd/go/#hdr-Modules__module_versions__and_more)
-support in go1.11 and later to manage its dependencies.
+rclone uses the [dep](https://github.com/golang/dep) tool to manage
+its dependencies.  All code that rclone needs for building is stored
+in the `vendor` directory for perfectly reproducable builds.

-**NB** you must be using go1.11 or above to add a dependency to
-rclone.  Rclone will still build with older versions of go, but we use
-the `go mod` command for dependencies which is only in go1.11 and
-above.
+The `vendor` directory is entirely managed by the `dep` tool.

-rclone can be built with modules outside of the GOPATH, but for
-backwards compatibility with older go versions, rclone also maintains
-a `vendor` directory with all the external code rclone needs for
-building.
+To add a new dependency, run `dep ensure` and `dep` will pull in the
+new dependency to the `vendor` directory and update the `Gopkg.lock`
+file.

-The `vendor` directory is entirely managed by the `go mod` tool, do
-not add things manually.
+You can add constraints on that package in the `Gopkg.toml` file (see
+the `dep` documentation), but don't unless you really need to.

-To add a dependency `github.com/ncw/new_dependency` see the
-instructions below.  These will fetch the dependency, add it to
-`go.mod` and `go.sum` and vendor it for older go versions.
-
-    GO111MODULE=on go get github.com/ncw/new_dependency
-    GO111MODULE=on go mod vendor
-
-You can add constraints on that package when doing `go get` (see the
-go docs linked above), but don't unless you really need to.
-
-Please check in the changes generated by `go mod` including the
-`vendor` directory and `go.mod` and `go.sum` in a single commit
-separate from any other code changes with the title "vendor: add
-github.com/ncw/new_dependency".  Remember to `git add` any new files
-in `vendor`.
+Please check in the changes generated by `dep` including the `vendor`
+directory and `Godep.toml` and `Godep.lock` in a single commit

 ## Updating a dependency ##

 If you need to update a dependency then run

-    GO111MODULE=on go get -u github.com/pkg/errors

-## Writing a plugin ##
-
-New features (backends, commands) can also be added "out-of-tree", through Go plugins.
-Changes will be kept in a dynamically loaded file instead of being compiled into the main binary.
-This is useful if you can't merge your changes upstream or don't want to maintain a fork of rclone.
-
-Usage
-
- - Naming
-   - Plugins names must have the pattern `librcloneplugin_KIND_NAME.so`.
-   - `KIND` should be one of `backend`, `command` or `bundle`.
-   - Example: A plugin with backend support for PiFS would be called
-     `librcloneplugin_backend_pifs.so`.
- - Loading
-   - Supported on macOS & Linux as of now. ([Go issue for Windows support](https://github.com/golang/go/issues/19282))
-   - Supported on rclone v1.50 or greater.
-   - All plugins in the folder specified by variable `$RCLONE_PLUGIN_PATH` are loaded.
-   - If this variable doesn't exist, plugin support is disabled.
-   - Plugins must be compiled against the exact version of rclone to work.
-     (The rclone used during building the plugin must be the same as the source of rclone)
-     
-Building
-
-To turn your existing additions into a Go plugin, move them to an external repository
-and change the top-level package name to `main`.
-
-Check `rclone --version` and make sure that the plugin's rclone dependency and host Go version match.
-
-Then, run `go build -buildmode=plugin -o PLUGIN_NAME.so .` to build the plugin.

+
+Hi!
+
+We understand you are having a problem with rclone or have an idea for an improvement - we want to help you with that!
+
+If you've just got a question or aren't sure if you've found a bug then please use the rclone forum
+
+    https://forum.rclone.org/
+
+instead of filing an issue.  We'll reply quickly and it won't increase our massive issue backlog.
+
+If you think you might have found a bug, please can you try to replicate it with the latest beta?
+
+    https://beta.rclone.org/
+    
+If you can still replicate it with the latest beta, then please fill in the info below which makes our lives much easier.  A log with -vv will make our day :-)
+
+If you have an idea for an improvement, then please search the old issues first and if you don't find your idea, make a new issue.
+
+Thanks
+
+The Rclone Developers
+
+-->
+
+#### What is the problem you are having with rclone?
+
+
+#### What is your rclone version (eg output from `rclone -V`)
+
+
+#### Which OS you are using and how many bits (eg Windows 7, 64 bit)
+
+
+####  Which cloud storage system are you using? (eg Google Drive)

-## Making a manual build of docker
-
-The rclone docker image should autobuild on docker hub.  If it doesn't
-or needs to be updated then rebuild like this.
-
-```
-docker build -t rclone/rclone:1.49.1 -t rclone/rclone:1.49 -t rclone/rclone:1 -t rclone/rclone:latest .
-docker push rclone/rclone:1.49.1
-docker push rclone/rclone:1.49
-docker push rclone/rclone:1
-docker push rclone/rclone:latest
