+The CI config files for rclone have taken care of forks of the project, so you can enable CI for your fork repo easily.

+rclone currently uses [Travis CI](https://travis-ci.org/), [AppVeyor](https://ci.appveyor.com/), and
+[Circle CI](https://circleci.com/) to build the project. To enable them for your fork, simply go into their

 ## Adding a dependency ##
 
-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.
+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.
 
-The `vendor` directory is entirely managed by the `dep` tool.
+**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.
 
-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.
+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.
 
-You can add constraints on that package in the `Gopkg.toml` file (see
-the `dep` documentation), but don't unless you really need to.
+The `vendor` directory is entirely managed by the `go mod` tool, do
+not add things manually.
 
-Please check in the changes generated by `dep` including the `vendor`
-directory and `Godep.toml` and `Godep.lock` in a single commit
-separate from any other code changes.  Watch out for new files in
-`vendor`.
+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.

+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`.
 
 ## Updating a dependency ##
 
 If you need to update a dependency then run
 
-    dep ensure -update github.com/pkg/errors
+    GO111MODULE=on go get -u github.com/pkg/errors

+
+```
+docker build -t rclone/rclone:1.49.1 -t rclone/rclone:1.49 -t rclone/rclone:1 -t rclone/rclone:latest .

+
+Sometimes Amazon Drive gives an error when a file has been fully

+happens sometimes for files over 1GB in size and nearly every time for
+files bigger than 10GB. This parameter controls the time rclone waits
+for the file to appear.
+
+The default value for this parameter is 3 minutes per GB, so by
+default it will wait 3 minutes for every GB uploaded to see if the
+file appears.
+
+You can disable this feature by setting it to 0. This may cause
+conflict errors as rclone retries the failed upload but the file will
+most likely appear correctly eventually.
+

+of big files for a range of file sizes.
